Here’s How To Fix It
By booting macOS from a USB flash drive, users can repair the system as well as upgrade to the most recent version of the OS.
If you can’t boot macOS from a USB drive, the option might be disabled by default. This can also happen if the bootable media is not properly created or the USB drive has a problem. It is also probable that the bootable media’s Disk partition and file system are incompatible with the system.
In today’s article, We’ll go over how to deal with all of these different factors and get the Mac to boot from the USB.
First, ensure the USB flash drive is properly connected and functional. You can connect a spare flash drive to check the USB port’s functionality. If you use the latest generation USB drives on an older Mac device, the system may not recognize them. So, use the appropriate USB drive in accordance with the support offered by the ports on your device.
As a further precaution, make sure the USB drive you’re using is not formatted with the MBR partition type, which is typically the default one on a new USB. Follow these steps to format the USB flash drive with the specified file system.
Note: This process will erase all the contents of the USB drive. Back up the data before attempting this process.
Users must follow the precise steps very carefully in order to create a bootable drive. If the procedure is interrupted or is not carried out correctly, the Bootable USB drive won’t function as intended.
Here is a detailed process for creating a bootable Mac OS (Ventura) USB drive.
Note: The USB flash drive must have a minimum storage capacity of 14 GB and be formatted with a GUID partition along with a Mac extended (journaled) format.
As a security feature, macOS disables the ability to boot from any external or removable media by default. Fortunately, you can enable this option from the Startup Security Utility. Here’s how to do it.
Older Mac devices running on OSX Snow leopard or prior do not have a recovery partition. And in case you are booting Mac using a USB flash drive for recovery purposes on such devices, and it does not work, internet recovery is the only option for you.
Also, this feature comes in handy for the newer mac devices that have the recovery partition damaged. This feature lets users install macOS from Apple servers.
Here’s how to use this on the Intel Based Mac.
Restart your Mac device.
As soon as the device boots up, press
Command + Option + R to reinstall the compatible version of macOS.
Command + Option + Shift + R to reinstall the already installed version of MacOS
For the newer Mac devices with M1, M1 Pro, M1 Max chipsets
Resetting NVRAM, PRAM, and SMC are the go-to solutions while troubleshooting common issues of Mac. Performing this solves most of the issues associated with the system configuration of Mac devices. This is one of the recommended fixes for the Mac that won’t boot.
The new generation Macs with Silicon chipsets perform this process automatically when the device restarts.
On older Macs, here’s how to reset the NVRAM or the PRAM.
Shut down your device and press the power button for some time.
Before you see the grey screens, press the Command + Option + P + R keys for a few seconds until you hear a beep sound.
This resets most of the settings on your Mac device. Finally, try booting MacOS from the USB.
To reset the SMC for different Mac devices, you can follow this thorough guide from our Website.

When your SD card doesn’t format, there’s usually an issue with your access to the card or an issue with your device preventing you from formatting it. While using another device is always an option, it’s best to know the reasons why your SD card won’t format.
Depending on the device you’re using and the way the SD card is connected, there are a few different causes and fixes that may or may not apply to your situation.
There are a few reasons that a person might want to format an SD card. For example:
You should format a new SD card to ensure that it’s error-free and set up for the device you’re using. This is why devices like cameras, phones, and others can format. They prepare the card for use by that specific device.
Formatting a card can erase the data and leave space for new information to be saved to the card.
Formatting an older SD card can help remove any errors or mistakes on the card. That enables you to prevent problems with saving files in the future.
Formatting an SD card on a computer also gives you many options about exactly how you want it formatted. That’s why it’s so important to know which device you’re going to use the card on and what file system it prefers.
Your SD card might not format because of a problem with your device or because the card is protected. Many SD cards can have multiple kinds of write protection to ensure no valuable data is deleted.
You can usually fix problems that prevent your SD card from formatting. If you’re unable to format a card multiple times after trying each solution, the card itself might have an error. At that point, it’s time to start considering replacement SD cards.
Start by checking that the SD card is ready to format. After that, address issues with the device on which you’re trying to format the card.
Before you start, you must back up any data on the disk. Not only does formatting delete the data on the SD card, but some of the solutions can make it harder to retrieve the data later if the drive is damaged or corrupted. Before starting any drive troubleshooting, the best thing to do is to be sure anything on the drive is saved elsewhere.
Two kinds of write protection can be applied to SD cards. One is a physical write-protection that you have to manually take off with the card in your hands. The other is software protection applied from a computer.
If your card is write-protected, you won’t be able to format it. Check for physical write protection first and then check using your computer.
If your card has a notch on the side, you may need a piece of tape to complete the process. That notch can prevent some devices from accessing the SD card.
If it works this time, the physical write protection was the issue. If it doesn’t, check for software-based write protection next.
Use the Diskpart utility to change permissions for your SD card.
Doing these should remove any write protection from your card. Try to format it again to see whether the problem is solved.
If you still can’t format your card – even if you’re using a device other than a computer to complete the format – try formatting it on a PC so that you can use Disk Management. Sometimes, after you complete a format in Disk Management, you can reformat the card in the device that will use it.
If the card still doesn’t format, you can try using Diskpart again to clean it.
When you use the Clean command in Diskpart, you’re telling the program to wipe all the data from the SD card and turn it into unused space. You can create new partitions on it once it’s clean and set it up for future use as well.
You should end up with a freshly formatted NTFS SD card. You can also choose to replace NTFS with FAT32 if you prefer to format it for devices that use the FAT32 file system.
Sometimes changing the drive letter of the SD card will help your device format it. You can choose any unused letter on your system.
If you can format it in Windows after changing the drive letter, try doing it again in the device the card is destined for. CHKDSK
The CHKDSK utility on Windows scans drives for errors and tries to fix them. As long as the card is connected to your computer, it’s treated as a drive. This means you can use utilities like CHKDSK to find problems on the SD card that prevent it from undergoing a format.
If CHKDSK finds problems but cannot repair them, you might need to consider purchasing a new card.
If you’re only having trouble resetting it on a specific device – like a phone or a camera – try resetting the device to default settings. It could be a problem with the device itself that prevents the card from formatting.
This is a last-ditch resort that might help – but often, if you come to this point, the card simply doesn’t work.
Unfortunately, an SD card that can’t be removed from read-only mode and won’t format is often a dead SD card. It saves the data on the card and warns you not to use it anymore when it doesn’t work any longer and has damage or unfixable errors.
If your SD card has reached this point, check out other options. It’s better to buy something new than risk losing your data with a dead card. Also, don’t forget to check your warranty. Sometimes you might be able to get it replaced for free.
When you are on an online conference app like Microsoft Teams, video sharing is a must. And we know how frustrating it can be when you have to give a presentation but can’t share your screen.
Although there are many reasons why screen sharing can fail, this happens quite a lot due to the internet connection. When the attendee who is trying to screen share has a poor internet connection, Microsoft Teams lags.
We have mentioned a few fixes to Teams Screen Sharing not working so you don’t have to get embarrassed while trying to give a presentation.Why Is My Teams Screen Sharing Not Working?
Before we move on to the fixes, let’s look for the cause of the issue. If one of these reasons apply to you, you can move on to its fix and try to use screen sharing on Teams.
Internet Connection: Your interconnection is very slow if your screen keeps on buffering and won’t connect you to screen share. The internet connection plays a vital role on apps like Microsoft teams.
Using Other Browsers: If you use Microsoft Teams on browsers, make sure it is from Google Chrome or Microsoft Edge. You can not use other browsers like Mozilla Firefox, Opera because screen sharing will not work on these browsers.
Permissions Not Granted: Certain permissions need to be granted if you are an attendee trying to share your screen. A message that says can’t share your screen will show if the permissions are not granted. You can ask the host to allow you permissions for sharing screen.
Many Activities in the Background: Your CPU gets strained when there are many apps running in the background. The CPU will not be able to reach every app you are using and hence the performance speed will be low.
You are Using Linux: This is sad news for Linux users because the Microsoft Teams app is available in Linux but screen sharing is not. You cannot share your screen if you are a linux user but use other features of Microsoft Teams.How Do I Fix Teams Screen Sharing Not Working?
Below are a few solutions you can try out to fix screen sharing not working. Make sure to check out the causes before going for the solutions. Start by logging off the call and joining it again and see if that works for you. If not, follow the steps given below.Check Internet Connection
Make sure to have good internet speed when you are trying to share screen on Teams. Screen sharing requires a high-speed internet connection for its smooth performance. If you have low internet speed you will face issues like not being able to share screen at all or glitching while sharing screen.
Sometimes restarting your router by turning it off and on also works. You can also give a call to your ISP if there’s any issues with the server.Close Background Apps
When too many apps are opened in the background, it consumes your CPU. This can make your device slow down and will increase the chances of lags. Close those background apps and activities so your CPU can have a rest and work in peace. Here’s how to do itCheck for Permissions
If you are a participant who is having issues on screen sharing, it might have been due to permissions. The permission to share screen needs to be granted by the host so the participants can share their screen. Ask for permissions to the host if you are a participant.
If you are the host/admin you need to grant permission to the participants so they can share their screens. Here’s how to do it:
If you use a Mac, you need to grant screen recording permissions from the settings. Here’s how to locate and turn the screen recording on:Lower Display Resolution
When your device is working on a higher resolution display and you try to screen share, it puts a burden on teams. Due to this screen sharing on teams becomes an issue. You can lower the display resolution and try to share the screen again. Follow these steps to choose display settings.Clear Teams Cache
If you have been using Microsoft Teams for a long time but do not clear its cache then there’s a high possibility of your device piling up that cache. Clear the piled-up cache so it does not create issues with the app.Update Microsoft Teams
There might be available updates of Microsoft Teams where the previous bugs and issues are fixed. Do not ignore these updates and keep your Teams up-to-date. If the current version of your app is having issues then go for the updates. Here’s how to do it:
Sony’s consoles are robust and reliable but come with odd errors. Perhaps the most strange is when the PlayStation turns on by itself. Is there a way to fix it?
Perhaps you don’t remember turning on a PS4 or a PS5, but it’s still there, ready to play in your living room. If it happens a couple of times, you know it’s not your error. It’s the device, as this is an error that exists.
The PlayStation can turn itself on because of random system glitches or hardware errors. The problem is most likely easy to fix, but if you’ve been experiencing other errors on the console, you may need to perform a reset.
Although we’re looking at an alarming problem, we know some of its possible causes.
If you identify the culprit, you can fix the issue faster. So, here’re the potential enemies:
The “HDMI Device Link,” which connects the TV to the PS4 or PS5, is malfunctioning. That’s because both the TV and the PlayStation have the technologies, and both may be activating simultaneously.
A Rest Mode feature turns on the console if certain conditions are met.
The console is out of date, which causes some compatibility issues.
There’s a random bug in the system. Fortunately, PlayStation consoles offer various ways to clean it.
There’s a random bug in the software. Likely, there’re easy ways to clean the PlayStation.
Your controller has some gunk or clunky buttons. Because the controller can turn on the console with its PS button, this might be the case.
There’s internal damage to the console. If you believe this is the case, it needs repairs.
We’re dealing with software bugs, system bugs, or hardware bugs.
We’re going through a series of easy fixes, and you can try them one by one until you find a solution that works for you.
The HDMI Device Link is a feature that enables multiple HDMI devices to work together with the PlayStation. It’s part of the CEC (Consumer Electronics Control) specifications. Its purpose is to make different devices compatible with each other. For example, you can make a TV and an Xbox turn on and turn off together.
One of its intended results is making the PS5 or PS4 turn on when your turn on a TV system and choose the PlayStation’s input. You may also customize your TV’s remote to turn it on.
As you see, it has all the ingredients to be the culprit of this particular problem. Perhaps your console is connected to a SmartTV, an audio system, a speaker, a recorder, and similar. And then, when you turn one of these systems off, so does the console.
Go to Settings.
Disable HDMI Link.
Go to Settings.
Go to System.
Uncheck the “Enable HDMI Device Link” box.
Like so, the PlayStation should be independent of your display and any other system that’s part of your entertainment center. It also won’t turn on when you swap the HDMI channels on your monitor and go past the PlayStation’s input.
If you keep it on, two things will happen:
When you press the controller’s PS button, the PlayStation and the monitor will turn on as long as the HDMI cable connects these two devices.
When you turn on the TV and go to the PlayStation’s HDMI input, the console will turn on automatically.
Now that you know, it’s up to you to leave the feature on or off.
Rest Mode is a standby mode that saves power. However, it can download games when you prompt the action from the PlayStation app. Like so, the PlayStation turns on by itself. So, you can turn the feature off altogether.
Go to Settings
Select Power Saving Settings
Select Set Features Available in Rest Mode.
Uncheck “Enable Turning On of PS4 from Network.” Also, uncheck “Stay Connected to the Internet.” As you see, even Spotify could turn on the console if it’s linked to the PS4.
Go to Settings.
Select Power Saving on the left side menu.
Select Features Available in Rest Mode on the right side.
Disable “Stay Connected to the Internet” and “Turning On PS5 from Network.”
A power cycle is a soft reset that helps erase bugs and random errors. We’re using it to make the update process easier. If the console needs an update (but your internet is unreliable), checking for manual updates is a good idea.
An update can heal a lot of compatibility issues. For example, your console may have problems with a new smart TV.
Let’s start with the power cycle:
Turn off the console by pressing and holding the power button.
Unplug all of its cables for one minute.
Plug the cables back.
Turn the console back up.
Now, let’s update the consoles via the interface:
Go to Settings.
Select System Software Update.
If there’s an update available, select it. It will download in the background.
Select System Software on the left side menu.
Select System Software Update and Settings on the right-side menu.
Select Update System Software if you see an available update.
Toggle on the two options on the menu to ensure the PS5 updates automatically. These options are: “Download Update Files Automatically” and “Install Update Files Automatically.”
The last solution we’re listing is resetting the console. It will erase any system and software bug affecting its normal functions.
Go to Settings.
Go to Initialization. It’s the option at the bottom.
Select Initialize PS4.
You can choose to reset and keep your data or delete everything.
Select System Software on the left side.
Select Reset Options on the right side.
Select Reset your console. Then, select to keep or erase your data and confirm.
If you came all this way, and the troubleshooting didn’t work, it probably means the console’s hardware is malfunctioning. Most likely, you’d have to take the console for repairs.
Still, let’s review what could be failing and whether you can fix it at home.
The PlayStation controller is dirty. Often, you can play as you eat and drink, and some of it may have spilled into the controller. You can use a microfibre cloth, plus a bit of Isopropyl alcohol, to clean it deeply.
The disk drive on the PS4 may be spinning out of control. There’s a screw that holds it in place, and you can find it to screw it back. It’s behind a plastic tray, and you need a Phillips #0 cross-head screwdriver for the job.
On the PS5, though, the storage is an internal SSD. If it fails, you may see this error as well.
The console may be overheating because of dust and rust accumulation. Cleaning the console is lengthy, but you can check our separate PS5 guides for the tasks. And if you don’t feel confident enough to clean it yourself, take it for repairs -you’d know this is the issue if the console feels hot on touch or because the console gets too loud when you play.
Other pieces that may fail include the CMOS chip, the CPU, the optical sensor, and others.
Can’t delete VPN connection? Here’s how to fix it quickly
A VPN can be your trustworthy ally when it comes to online privacy, but sometimes even VPNs can trigger some annoying issues.
For instance, you might find it difficult to remove VPN profiles completely from your computer. But you shouldn’t worry; we got you covered.

We can all agree and acknowledge that a VPN can save you from a lot of hassle. From a connection’s privacy and security standpoint, of course.
The VPN client should handle every other step so that you can enjoy a clean, secure, and private browsing experience without putting too much time and effort into it.
But things might not be so great all the time, since VPN, like any other software, is prone to occasional errors. Not errors per se, but issues.
Either way, sometimes certain VPN events might hinder your ability to enjoy this type of service as you should.
For instance, you might discover that you can’t delete a VPN connection from your PC.
Note that this is not the same as not being able to disconnect from your VPN, which we previously covered. Turns out there are a few steps you can take if you discover you’re suddenly unable to pull the plug on your connection.
However, not being able to remove a VPN connection profile from your computer has some different implications. And naturally, it can be solved in a different manner.How to delete a VPN connection? 1. Uninstall the VPN app
Hit the Win key on your keyboard
Type Add or remove
Select the Add or remove programs option
Locate the VPN app you wish to remove from your PC
Select the VPN app
Follow the on-screen instructions to proceed with the removal
Once the uninstall process comes to an end, you shouldn’t be able to see a VPN profile any longer.
Reliable VPNs such as Private Internet Access treat privacy seriously and keep a clean shop, whether it’s installation or removal we’re talking about.2. Remove the VPN connection manually
On Windows 10, open the Settings app
Head to the Network & Internet section
Locate your VPN connection profile
Select Delete from the context menu
That should’ve removed any old connection profile that still lingered after you’ve uninstalled the client. Note that attempting to delete an active connection won’t work.
Thus, make sure you’ve uninstalled the app before you attempt to delete the VPN connection profile. If a connection is active, or the VPN client still installed/service still running, the Delete option will be greyed-out.
On Windows 10, hit the Win key on your keyboard
Type Device on your keyboard
Select Device Manager from the Start Menu
Expand the Network adapters section in the manager
Select Uninstall from the combo menu
Confirm its removal
That’s it, you’ve managed to delete a VPN connection from your computer entirely. Not only have you removed the client, but also made sure that there’s no residual connection profile or TAP driver associated with the VPN on your computer.
Sometimes it’s necessary to perform these seemingly useless operations, as many VPN providers intentionally leave these files behind.
The reason why they do this is that if you change your mind one day and reinstall their service, the process will be less complicated.
However, multiple TAP drivers and/or connection profiles that are no longer used or working might impede another VPN’s ability to run as intended. This type of situation creates conflicts between VPN software and should be avoided.Deleting a VPN connection is not a complicated task
All things considered, removing a VPN connection from your computer entirely is not exactly rocket science.
The bottom line is that some VPN clients will intentionally leave some residual files behind. The reason why they resort to this is that you might want to reinstall their service later on, and if you do, the service can simply pick up where it left.
However, if you’re pondering on removing your VPN to replace it with another service, it would be a wise thing to perform the steps we’ve described above.
Keeping old configuration files, connection profiles and TAP drivers can seriously affect your new VPN’s ability to perform as intended.

The whole premise that Snapchat is built on is disappearing snaps and messages. While they kinda dropped the ball on the ‘messages’ front, snaps are still supposed to disappear right? However, if the Snapchat Stories are not going away for you, it may be a bug or something. Let’s see how we can fix the issue.
What are Snapchat Stories?
Snapchat lets you upload ‘stories’ which are basically snaps that everyone in your friends list can view. Quite similar to Instagram stories (which came after the Snapchat counterpart), these stories stay visible on your account for 24 hours.
Snapchat also lets you customize the audience for your stories. With private stories, you can choose the users that you would like to have access to view your stories. On the other hand, public stories and those from verified accounts can be visible to anyone in the world. These stories may appear as ‘Subscriptions’, under your friends’ stories on the ‘Story page’.
Why are Snapchat stories not going away?
Well, once you view a Snapchat story, whether it is your friend’s or a subscription, it is supposed to disappear, so that you do not view it again by mistake. While this is not that much of a problem for users that only have a few subscriptions, it definitely makes a difference when you are subscribed to hundreds of them. You definitely do not want to keep watching the same user’s story pop up.
Recently, users have noticed that watched stories are not disappearing. While these stories do not actually disappear but move to the end of the queue, they now seem to reappear when you refresh the page (or exit the app and come back).
This seems to be a bug resulting from the last update of the app. Users have noticed that no matter how many times you refresh the page, the stories keep coming back as ‘not yet viewed’. This also seems to affect your own Snapchat story. Even after you view your story, the indicator shows that you haven’t.
How to fix the issue on Android?
Well, seeing as this is a bug, there is little you can do from your end to fix it. The bug does not seem to keep stories on the account longer than 24 hours though. It just seems to not mark viewed stories. This means you do not know which stories you have already viewed. Additionally, you cannot tell if a user has uploaded a new story since the indicator stays the same.
The easiest way to fix this bug is to wait for the Snapchat team to send out an update for it. Snapchat is usually quite prompt when it comes to fixing bugs on their app.
All you can do in this case is keep an eye out on the App Store for an update to the Snapchat app. If you have Auto-update enabled for your app, you need not even worry about this.
2. Rollback to a previous version of the app
Another thing you can do is to roll back your Snapchat app to a version before this bug. It should be noted, however, that in order to roll back an app you will have to prevent it from accessing future updates. Use the guide below to disable Auto-updates on the Google Play Store.
Now you need to uninstall the latest version of the app that you have on your device. To do so, simply tap and hold on the app icon and select ‘Uninstall’.
The last step is to install an older version of the app. You can use the APK in the link below.
Download: Snapchat 10.86.5.61 (APK)
Download the APK from the link above and install it (here’s a guide to installing an APK file on Android). You will need to allow the installation of third-party apps that will pop up when you try to install it.
Tip: Now go ahead and launch the app as you normally would. Once you know there is a new update to the app, you can uninstall this older version, and reinstall the app from the Google Play Store.
In order to prevent the Snapchat app from updating itself, you need to prevent Auto updates. The Google Play Store gives you an option to disable Auto-update on selected apps.
To do so, launch the Google Play Store app, and locate the Snapchat app. Now tap the three dots in the top right corner and untick ‘Enable auto-update’.
How to fix the issue on iPhone and iPad?
Unfortunately, there is no easy way to sideload an app on iOS devices. For iOS devices, you can try this simple fix below, or simply wait for the next update from Snapchat.
Open the app and log out.
Uninstall the Snapchat app on your Apple device.
Restart your device.
Reinstall the app from the App Store.
Log back in.
This should fix any glitches from your end. If the bug continues, you will have to wait for the official update from Snapchat.
