Suggested January 2024 How To Create A Os X El Capitan Boot Installer Usb Flash Drive
Many Mac users like to make a bootable installer drive for installing OS X El Capitan, whether for performing a clean install, or for making it easier to install OS X 10.11 onto multiple Macs. We will walk through creating a bootable install flash drive from OS X El Capitan with the final public version.
Before getting started, know the requirements necessary to make a bootable OS X El Capitan installer drive are as follows:
An 8GB or larger USB Flash Drive like these, this will be formatted and turn into the OS X El Capitan bootable installer
The OS X El Capitan installer application must be on the Mac and in the /Applications/ folder, download OS X El Capitan here if you haven’t done so yet (yes. you can re-download it)
Presumably you have already made the USB flash drive into a Mac compatible format with Disk Utility, if not you can follow the directions here to format a drive for Mac OS X compatibility HFS+.
When you’re ready, plug the USB / flash drive into the Mac with the OS X El Capitan installer application on it.1: Rename the USB Flash Drive to Become the OS X El Capitan Bootable Installer
The next thing you’ll want to do is rename the target volume that you wish to turn into a bootable installer drive, in this case an external USB flash drive. To avoid any confusion, we’re naming the USB drive to “ElCapInstaller” (without the quotations), though you can name it whatever you want as long as you adjust the command line syntax to match.
You can do this through the Terminal or the Finder as shown above.2: Make the OS X El Capitan Bootable Installer Drive with a Terminal Command
Launch the Terminal application, found in /Applications/Utilities/ and enter the following command exactly (unless you changed the target volume name from ElCapInstaller to something else) onto a single line, the text will wrap because it is long, but it’s important to have proper syntax:
sudo /Applications/Install OS X El chúng tôi --volume /Volumes/ElCapInstaller --applicationpath /Applications/Install OS X El chúng tôi --nointeraction
Hit the Return key and enter the administrator password when requested.
You’ll then see the following screen text in the Terminal:
The target USB disk or flash drive will be erased first and then copy the files to it so that it will become a bootable OS X El Capitan installer. This can take a while to complete, so wait for the “Done” message before continuing.
When you see “Done”, that’s it, your OS X El Capitan installer drive has been created, it’s bootable, and you can use it to update as many Macs as you want to with OS X 10.11.
To boot from the installer drive, hold down the Option key during Mac system start, and select it from the startup volume menu.
Otherwise, you can insert the installer USB disk / flash drive into any Mac and launch the installer directly from the drive.Can you show me how to make an Install OS X El Capitan boot drive?

Apple has officially released OS X El Capitan for the Mac, adding some new improvements as well as bringing parity with changes in iOS 9, released two weeks ago. OS X El Capitan (version 10.11), can be installed on any Mac that runs OS X Yosemite: simply download the free update from the Mac App Store. The release does not feature anything radically new — like the major visual overhaul that came last year — but there are new features as well as a strong focus on overall performance and stability improvements.
Here’s what’s new in Apple’s latest version of the Mac operating system …
Apple has made some significant to changes to Spotlight, the system search function that pops up in the center of the display when you hit Command+Space. First off, in El Capitan, it doesn’t have to be in the center. As silly as it sounds, you can now freely resize and position the Spotlight box to match your own preferences for the first time. Apple has also bolstered the library of possible search terms to include more transient and informational data, like weather, sports scores or even YouTube and Vimeo video results. You can also make your search queries a lot more casual and Spotlight will understand what you mean. Rather than typing with obtuse filter syntax, you can use natural language queries like ‘email from Joshua last year’ or ‘presentations from last week’. These queries work great, are easy to remember and formulate, and work in apps like Finder and Mail as well as the Spotlight search bar.
Crucially, once you upgrade Notes to use iCloud Drive, El Capitan is required to sync with iOS 9. Yosemite users have no choice but to upgrade their Macs if they want to retain cross-platform harmony. Also keep in mind that sketches can only be created and edited on iOS 9 devices — they are only viewable on OS X.
Matching Chrome from three years ago, Safari 9 adds Pinned Tabs. Essentially, you can put your favorite websites permanently in your URL bar as ‘small buttons’ on the left side of the tab bar. The websites stay loaded, so you can quickly switch to them at any time. Another appreciated addition in Safari 9 is revamped AirPlay support: rather than streaming your entire Mac desktop to the Apple TV, you can stream just specific videos embedded in pages. This doesn’t work on all websites, unfortunately, but popular websites like YouTube are supported.
Full-Screen Split View
A common workflow in El Capitan will be to use the new windowing features to put Safari at about 2/3rds width, with a smaller utility or social networking app filing the rest of the space. This is thanks to the addition of Split View for full-screen apps.
Hold down on the green zoom button on any window to activate Split View. Drag the window to either the left or right side of the screen to snap it as a ‘full screen’ app, even though that name is a bit of a misnomer because it isn’t actually filling the whole width of the screen. You can then choose another full-screen app for the other side of the screen. This now mirrors Split View multitasking on iPad, although you can drag the divider to any arbitrary ratio of content and drag files between windows. It adds a lot more flexibility to workflows and is especially useful on larger-screen iMacs … where having just one app dominate the display was comical. The combined Split View appears as its own space in Mission Control and can be dragged around like a normal full-screen app. Most apps adapt beautifully to the split-screen layout but there are some exceptions; Notes refuses to lose its left-hand column so isn’t really suitable as a skinny-width app unless you’re using a single note window.
It’s also worth noting that the new Mission Control drops window labels and hides desktop previews until you slide your mouse towards the top of the screen, which I personally think is a regression. Text labels show temporarily on hover but you lose the glanceable nature of the old behavior.
Updates to Mail in OS X El Capitan heavily respect the adoption of full screen. In earlier versions of OS X, Mail was not a good Full Screen citizen. Composing a new mail message would open a window outside of the Full Screen space. Yosemite added an integrated compose window and El Capitan builds on this further by adding a tab bar, so you can compose multiple messages at once. Similar to iOS, you can also slide the compose window down to refer to other messages before you finish sending your message.
For graphics, Apple has implemented Metal, its high-performance drawing framework, at the core of El Capitan so that it powers all system-level graphics operations. This should provide better frame rates and snappier transitions across the OS — it’s particularly noticeable for the full-screen sliding animation when switching between maximized windows and desktop spaces. Metal is also available to third-party developers, so game creators will be able to use it to push more performance out of the hardware. Apple also claims it has improved the foundations of OS X in other ways to make everything feel faster. The company claims speed improvements from 4x faster PDF rendering to 1.4x faster app launching. Naturally, real-word gains will vary based on a multitude of factors.
Like any operating system update, there’s a bunch of minor improvements and refinements across the system. Following iOS 9 and watchOS, OS X gets the San Fransisco font makeover. There are also minor redesigns to many of the stock interface elements, including some moderate shadowing. It’s personal preference of course, but I think it looks way better than the buttons and controls used in Yosemite. Maps gets Transit directions, Photos finally lets you geotag pictures and supports third-party editing extensions, and there’s even a Find My Friends widget in Notification Center. You can even shake the mouse cursor to enlarge it in case you lose track of what you are doing. There also some welcomed additions for Chinese and Japanese users, including a special system font for Traditional and Simplified Chinese characters (which is apparently better for readability), improved trackpad OCR and as-you-type translation of Hiragana into Japanese.
In summary, El Capitan is not the biggest update in Mac history, but that doesn’t mean there aren’t a variety of changes and improvements to enjoy. It’s expected for a maturing platform to have less major additions and it doesn’t really matter when the updates are free.

Many Mac users running a modern version of OS X El Capitan have noticed the Secure Erase Free Space feature has gone missing from Disk Utility. What the “Erase Free Space” feature did (and still does in prior versions of Mac OS X) was overwrite the free space on a drive to prevent file recovery, adding a layer of security and privacy to file removal, much in the way that Secure Empty Trash performed a similar function of overwriting data after removal.
For those wondering, these features were removed from the modern version of Disk Utility in Mac OS X because they do not work on SSD volumes, which are becoming more commonplace and nearly all Mac laptops ship with them by default now. But not everyone has an SSD drive, and thus some users may still wish to perform a secure erase of free space on their Mac hard disk. To achieve the same secure erase in modern versions of Mac OS X you’ll need to turn to the command line. And yes, this works to erase free space on older versions of Mac OS X too, but since they can do the same task with Disk Utility it’s perhaps a bit less relevant to the prior releases.How to Secure Erase Free Space on Mac OS X El Capitan Drives via Command Line, Without Disk Utility
Back up your Mac before attempting to use these commands. The command line requires precise syntax and is unforgiving, improper commands could lead to the unintended removal of data you do not want to delete, permanently, as this is a secure erase function. You have been warned, so backup your Mac data first, then proceed at your own risk.
To get started, launch the Terminal (found in /Applications/Utilities/) and use the following general syntax, replacing level and drive name as appropriate:
diskutil secureErase freespace (level 0-4) /Volumes/(Drive Name)
(level 0-4) is a number indicating the number of passes to write to the free space, ‘freespace’ indicates you are erasing only the free space and not the entire drive itself – a critically important difference – and (Drive Name) is self explanatory. Users can also choose the disk identifier if desired. If you aren’t sure of the name of the drive, using diskutil list will show you all mounted drives and partitions. If the drive in question has a space in the name, you should place it in quotes or escape it with backslashes.
For example, to perform a secure erase with 35 passes on free space on a drive named “Macintosh HD” you could use the following command string:
diskutil secureErase freespace 3 "/Volumes/Macintosh HD"
Hitting return will instantly begin the secure erase of any free space. This is irreversible, so as we’ve mentioned a dozen times already, be sure the syntax is exact.
verbs. Ownership of the affected disk is required.
Level should be one of the following:
o 0 – Single-pass zero-fill erase.
o 1 – Single-pass random-fill erase.
o 2 – US DoD 7-pass secure erase.
o 3 – Gutmann algorithm 35-pass secure erase.
o 4 – US DoE algorithm 3-pass secure erase.
That’s all there is to it, and this is how you can continue to erase free disk space on a Mac running OS X El Capitan or later with the newly limited Disk Utility. Another option is to use an old version of Disk Utility in modern versions of Mac OS X, either from a boot drive or recovery mode, of an older Mac OS release, or with the application itself, but that is generally not recommended.
And yes, this works on both standard hard disk drives with spinning platters, and modern SSD disks, though with an SSD drive the feature is less relevant as TRIM / garbage collection should handle the file removal on it’s own. For SSD volumes, a better option is to enable and use FileVault disk encryption on the Mac, which encrypts data on the drive making it unrecoverable without the FileVault key, thus obviating the need to securely erase free space on the volume.
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.
Casual Mac users don’t really care to join OS X’s Developer program, which can set you back $99 a year. Neither are they interested in Beta versions or have that kind of money to spend on something they know they won’t be using. However, Apple has now introduced a new OS X Beta Seed Program, in which users can download and test new beta versions of OS X, by simply signing up with an Apple ID. The best part? It’s entirely free.
This free status of that OS X Beta Seed Program will potentially mean that many developers may uptake the pre-release versions of OS X. This way, a lot of bugs and mistakes can be easily ironed out with some feedback, and in truth, this should benefit both Apple and the consumer. Apple has finally realised that charging a fee for pre-release versions of the final free GM isn’t quite right, and for us, the move to introduce the Beta Seed Program is inarguably a step in the right direction.
So, if you want to get involved, follow the simple steps below:
2. Once entered, agree to the “Terms and Conditions.”
Once you’re signed up, any pre-release beta builds or updates will be seen through the Mac App Store. Rumours are that Apple will be revamping its OS X interface this year at WWDC, and if they indeed do introduce a iOS 7-style OS X design, we think many users will enroll to try the beta version.

In the recent version of Mac OS X, the web server is one of the component that is built-in by default. Prior to Mountain Lion, users can easily turn on the web server via the “Web Sharing” option in the Sharing Preference pane. That component was removed in Mountain Lion. In this tutorial, we will show you how to activate the web server in Mountain Lion, as well as setting up PHP, MySQL and PhpMyAdmin. At the end of this tutorial, you will have a MAMP (Mac, Apache, MySQL, Php) server running on your Mac.Starting the Apache server
Apache server is pre-installed in Mac OS X, so there is no need to install it. However, to start the Apache server, we will have to use command line in the Terminal.
2. Type the following command:
To restart the Apache server, use the command:
To stop the Apache server, use the command:
apachectl stopActivating the PHP module
The Apache server is only good enough for you to run static HTML files. If you want to run a more complicated setup, like installing WordPress, you will need to activate the PHP module.
PHP is pre-installed in Mac OS X as well, but it is not included by default.
1. In the terminal, type:
2. Remove down the list until you see the line:
#LoadModule php5_module libexec
Remove the “#” in front of the line, so it becomes:
3. Save the changes (using shortcut key “Ctrl + o”) and exit (using shortcut key “Ctrl + x”). Restart Apache.
The PHP module is now activated.Configuring Sites folder
1. Open the Finder and go to your Home folder (the folder with a Home icon and your username). Create a new folder “Sites” if it is not available.
2. Back to the Terminal, type the command:
Replace the “username” with your login username. In my case, it will be “sudo nano /etc/apache2/users/damienoh.conf“.
3. Copy and paste the following code to the conf file.
Options Indexes MultiViews AllowOverride All Order allow,deny Allow from all
4. Next, type the command:
and paste the line:
Restart Apache serverSetting up MySQL
MySQL is not included in Mountain Lion, so you will need to download and install it manually.
1. Go to MySQL Download site and download the MySQL installer for Mac. For easier installation, you might want to grab the .DMG image than the one in chúng tôi format.
2. Once the download is completed, open up the installer, you should see two .pkg files and one .prefPane file. Install all three of them.Setting upi MySQL root password
In the Terminal, type the command:
Replace the “yourpasswordhere” with your own password.
Note: Do not confuse this password with your Mac login account. They are not the same. This is the password for the script to access your database.
Note: Removing MySQL is not as straightforward. Run the commands, line by line, in the terminal:
Open the file “hostconfig” with the command “sudo nano /etc/hostconfig” and remove the line MYSQLCOM=-YES-.Installing PhpMyAdmin
PhpMyAdmin is basically a bunch of PHP files, so installing them is a breeze.
1. Download PhpMyAdmin from its website.
2. Extract the compressed file to your Sites folder and rename it as “phpmyadmin”.
3. Open the “phpmyadmin” folder and create a new folder call “config”. Change its permission with the command:
6. Go to the “Authentication” tab and enter MySQL root password in the “Password for config auth” field.
7. Lastly, enter the following commands in the terminal:
It will probably be easier if you install a third party tool like MAMP, but that will add duplicate features to what is already available in your Mac. With a little tinkering, you can easily get your Mac to be a web server for all your web hosting needs.
