Suggested January 2024 How To Use Energy Saver Settings On Mac For Better Battery & Power Management
If you’re using a desktop Mac, like an iMac or Mac Pro, you’re probably less concerned about power management than someone using something like a MacBook. But there are still chances to reduce your home electricity bill, too. You’d be surprised the difference tweaking a few macOS settings can make, especially if you’re someone who leaves their computer and display on 24/7. Here, we’re going to go through some of the settings you might want to take a look at for improving power management on the Mac.
All of these settings live in the Energy Saver area of your Mac’s Preferences app, and the options you see will vary depending on what computer you are using. The screenshot was taken on a 2023 MacBook Air, and the other on a 2023 Mac mini, but if you’re using a MacBook, MacBook Pro, or MacBook Air you’ll see different settings for battery power. Notably, you’ll have two panes – one will be for when your computer is running on battery, the other for when it’s on power.
With that said, here is generally what a Mac’s energy-saving options look like, the screenshot is from a desktop Mac, but further below you’ll see a screenshot for a Mac laptop. We’ll also run through what all the options do.
Now let’s take a look at the options and what they do.
“Turn the display off after” – This tells your Mac when to turn off the display. If that’s an internal display it will be turned off completely. If you’re using an external display it will likely enter low-power mode. You can wake it up by pressing a key on the keyboard or by moving the mouse.
“Prevent the display from sleeping automatically when the display is off” – This is a way to ensure your Mac stays powered on and awake, even if your Mac puts its display to sleep.
“Slightly dim the display on battery power” – This will automatically reduce display brightness when the Mac is running on battery power. This is limited to Mac laptops, of course.
“Put hard disks to sleep when possible” – This option is left over from when all Macs had spinning hard disks in them. That isn’t really the case anymore, but if you’re using an external hard disk or have a Mac Pro with internal spinning disks, this option will turn them off when they aren’t being used.
“Wake for network access” – Most people will not need this, but if you have a media library or other shared resource – like a printer – this checkbox enables another computer to wake your Mac up if it’s needed.
“Enable Power Nap” – Power Nap allows your Mac to be woken from sleep to carry out some functions, like running a Time Machine backup or sending and receiving email. The display won’t be turned on when this happens and Power Nap only wakes a computer if it is plugged in, too.
“Start up automatically after a power failure” – This instructs your Mac to automatically power back on once power is restored if it wasn’t correctly shut down. It’s great for those with flakey power but also need their computer to be on 24/7.
Making use of energy-saving options is still a good idea even if you’re using a Mac that is always plugged in. Apart from saving money, turning your display off when not being used will hopefully make it last longer and the same definitely goes for things like spinning hard disks, too.
This guide is based on macOS Catalina and the latest and greatest versions of macOS at the time of writing.
If you are new to macOS Catalina 10.15 and later you might need to learn a few things like how to back up an iPhone or iPad, for example. Sidecar is also a big addition to macOS Catalina and you absolutely should be making use of it.

Energy Efficiency refers to using less energy to produce the same results, which is nothing but eliminating wastage. Energy efficiency can be achieved using technology that performs the same task with comparatively less energy.
IoT can be used to obtain both Energy Sustainability & Efficiency, the trending technology. IoT, along with AI, cloud computing, data transfer systems, data analysis, communication, and other technologies, makes energy conservation possible.
Following are the applications of IoT in the energy sector −IoT-based Energy Monitoring Systems
IoT devices connected to energy systems use Machine Learning to predict energy consumption in the future. This allows energy companies to develop product strategies and helps utilities improve their demand-based pricing models. So, IoT, along with Machine Learning(ML), avoids outages and wastage. Hence, IoT-based Energy Monitoring Systems(EMS) present insights for energy conservation.Smart Home Smart HVAC device
HVAC refers to Heating, Ventilation, and Air-Conditioning. HVAC systems consume a lot of energy, about 60% of the total in residential and commercial buildings. So, reducing energy consumption at this level is highly important, and IoT can achieve this!
Installing IoT devices makes it easy to monitor the system’s performance, turning them on/of automatically, changing the temperatures using data of user’s behaviour at different weather conditions(by using a smart thermostat), etc.
Smart HVAC components include – a smart thermostat, motion sensors, a remote controller, and a hub that stores and analyzes the data. We can reduce electricity bills, address performance issues and prevent downtime, provide better conditions for residents, lower carbon emissions, etc.Smart lighting
Almost 20% of energy is consumed for lighting, which results in 6% of CO2 emissions. So there is a lot to fight against with the energy crisis in this area. Though our government is introducing LED lamps which use 85% less energy than incandescent lamps, many need to come forward to accept this LED technology. Also, there is a wastage of energy due to manual switching systems, so it’s high time to move towards smart lighting systems. This system uses different kinds of lighting control sensors like motion, occupancy, voice, IR, Ultrasonic, temperature, etc. Using IoT, one can manage the lighting with their smartphone.Improving Insulation
Similarly, in hotter countries, improper insulation makes tenants turn on Air Conditioners quite often. Here IoT is used to identify areas where temperatures rise above the optimum.Smart Grids
The energy grid is a network for electricity delivery to various locations. Smart grids, unlike traditional grids, use technologies such as sensors, smart meters, and networks to increase intelligence and efficient energy usage. Smart meters provide real-time data about energy consumption using IoT and allow operators to understand energy requirements. Smart grids can also be integrated with renewable energy sources like hydro, solar, wind, etc.
The meter across the grid must be upheld by two principles – cybersecurity and connectivity.Connectivity
To share the data continuously with the operator, reliable connectivity must be maintained, without which there will be no efficient supply.Cybersecurity
While the robust connectivity enables smart grids to share accurate data with the operators, it also exposes them to the risk of hacking. This attack threatens consumers, government agencies, operators, etc. So having a unique digital identity for a smart grid would reduce the risk.Equipment monitoring and Maintenance
Equipment in industries sometimes fails to perform as intended due to faults, resulting in low performance and low operational efficiencies. IoT devices installed in critical areas help monitor the environment around them, find equipment errors, understand the uptimes and downtimes, etc. Monitoring the issues using IoT devices helps reduce energy wastage, lower the cost of damage, and identify parts that need to be replaced or repaired.
Using a digital twin, a digital representation of a physical object, we can easily monitor the system and make changes after testing on the digital twin. This helps in reducing the possible failures in the system. This digital twin is constructed by gathering information from physical objects through 3D lasers, drones, cameras, sensors, and IoT devices.Conclusion
IoT is highly important in obtaining energy sustainability and efficiency, whose main goal is optimizing production, distribution, and consumption. IoT contributes to reducing the carbon footprint.
Greenpeace has often been critical of big data-center operators like Facebook for their impact on the environment, but on Wednesday it said some online firms are improving their practices and may even be the vanguard for renewable energy use.
Facebook, Google, Apple, and some other tech firms have been investing heavily in renewable energy sources such as wind, hydro and solar. While cautioning that they have more work to do, Greenpeace said the companies are showing how big organizations can use their buying power to reduce dependence on fossil fuels.

“The changes I’m seeing from the companies in the room here are giving me big hope,” said Gary Cook, a senior IT policy analyst at Greenpeace, at an event in San Francisco attended by Facebook, Google, Rackspace, Yahoo and other companies that have made commitments to renewable energy.
It’s a big change from two years ago, when Greenpeace was running its “Tell Facebook to Unfriend Coal” campaign. At the time, it slammed the social network for building two giant data centers in Prineville, Oregon, where the main source of power is coal-fired plants.
Under pressure to improve, Facebook is locating its next data centers in Iowa and Sweden, where renewable energy is plentiful. On Wednesday, Facebook announced that the Iowa data center will be powered entirely by a nearby wind farm when it begins operations in 2023. The data center in Sweden will use 100 percent hydro power, Facebook has said.
What’s encouraging, according to Cook, is that Facebook’s move in Iowa encouraged the local utility, MidAmerican Energy, to increase its own investment in renewables. “It shows the ability of a big company like Facebook to leverage their buying power to drive change,” he said.
Facebook, Apple and Google have also pushed for wider availability of renewables in North Carolina, where they each operate data centers. Google worked with the local utility, Duke Energy, to introduce a new tariff for companies that are willing to pay a higher rate for renewable energy.
The paperwork to introduce the tariff isn’t complete yet but Google is hopeful it will be filed soon, said Gary Demasi, who’s in charge of Google’s data center location strategy.
Greenpeace isn’t suddenly heralding online firms as saviors of the environment. “You have a big part of the sector that’s still focused on growing as fast as they can, and not necessarily looking at how they are growing,” Cook said in an interview.
Nor are all cloud providers on board. Amazon Web Services is one of the world’s biggest cloud providers, but “you’d be hard-pressed as a customer to get any information about how much energy they’re using or what type of energy they’re using,” Cook said. And Amazon provides the computing infrastructure for a lot of other online brands, he noted.
But the environmental group is recognizing that some firms have taken meaningful steps to reduce their dependence on fossil fuels.
Energy regulations make it harder to consume renewables than it should be, and there’s not yet a “cookie cutter” approach that can be applied from one project to the next, said Bill Weihl, who runs Facebook’s sustainability efforts and previously had the same job at Google. But utilities are becoming more open to partnerships with data center operators, he said.
It helps when you’re as big as Facebook and Google, who can apply pressure in return for the promise of their business.
“If we’re going to bring you millions of dollars in revenue, we really think we should get the product we want,” Google’s Demasi said.
The imperative to make cloud services greener is great. Almost half the world’s population will be connected to the Internet by 2023, according to research from Cisco. And if the cloud computing industry were a country, it would already be the sixth-largest consumer of electricity, just behind Russia, Cook said.
Efforts like the one to create a new energy tariff in North Carolina could pave the way for other utilities to take similar steps, Cook said, but the work is far from complete.
“The story’s not yet been written; it’s being written now,” he said.
Learn how to set up Touch ID on a MacBook or Magic Keyboard, enroll your fingerprints in the system, and use it to quickly unlock your computer, make purchases on websites with Apple Pay, and much more.
Since October 2023, Touch ID has been available on MacBook Pro and MacBook Air. The Touch ID doubles as the Power button, too. Besides that, you can get the Magic Keyboard with Touch ID and use it on any Apple silicon Mac like Mac mini, Mac Studio, iMac, etc.
What you can do with Touch ID on your Mac
Unlock your Mac
Authorize Apple Pay purchases on the web
Make purchases in App and iTunes stores
Unlock certain System Preferences panes that require a password
Open password-protected notes in the Notes app
Access the Passwords section in Safari preferences
Use fast user switching
Authenticate compatible third-party apps, like 1Password
Note: While you can press and hold down the Touch ID button for a few seconds to put the Mac to sleep, Apple recommends choosing Sleep from the Apple menu.
macOS may ask you to enter your account password instead of using Touch ID:
If you’ve just restarted your Mac
If you’ve logged out of your user account
If your fingerprint isn’t recognized five times in a row
If you haven’t unlocked your Mac in more than 48 hours
If you’ve just enrolled or deleted fingerprints
So, just how secure is Touch ID on the Mac?
Touch ID and your security
Touch ID on the Mac provides the same strong security and privacy that iOS users have grown accustomed to. That’s because your Mac comes with a special chip that has the so-called Secure Enclave, which keeps mathematical representations of your saved prints, as well as Apple Pay tokens, safely encrypted. All communications between the Touch ID sensor and the rest of the system go through that chip.
The main processor, the operating system, and any first or third-party apps cannot access the Touch ID sensor directly. All they get from the Touch ID subsystem is a simple confirmation upon a successful match. Apple does not save your fingerprints into the cloud, nor does it synchronize saved prints between devices via iCloud.
How to set up Touch ID on Mac
While setting up your new or erased Mac, you’re asked if you would like to use Touch ID. This is true even when you set up your Mac mini, Mac Studio, or iMac using the Magic Keyboard with Touch ID.
However, if you didn’t set up Touch ID then or want to add more fingerprints, follow these easy instructions:
Launch System Settings on your Mac.
Select Touch ID & Password from the left side.
Enter your Mac’s password and hit Unlock.
Now, repeatedly place (not press) and lift your finger on the Touch ID sensor of your MacBook or Magic Keyboard until all the patterns are filled with red-pink lines. Make small adjustments to the position of your finger each time so that the system captures the edges of your print.
You can now unlock your Mac using your fingerprint and do everything else that Touch ID supports.
You can register up to three fingerprints with Touch ID on your Mac versus five on your iPhone or iPad.
What to do after setting up Touch ID
You can select to use Touch ID for:
Unlocking your Mac: Bypass typing your Mac account’s password on the login screen and unlock the computer with your fingerprint.
Apple Pay: Use your fingerprint to make purchases with Apple Pay.
iTunes, App Store, and Apple Books: Use Touch ID to authorize purchases made on the Mac App Store, iTunes Store, and Books Store.
Autofill passwords: Confirm using Touch ID to fill saved passwords from iCloud Keychain.
User switching: If you have created multiple users for your Mac, you can switch between them using Touch ID.
Like with your iPhone and iPad, macOS lets you name any saved fingerprint (i.e., Middle Finger, Right Thumb, and so forth) so that it’s easier to identify in the list. However, you cannot place your finger on the Touch ID sensor to have System Settings highlight a matched print in the list, as you can on iOS.
Keep in mind that you may be asked to enter your administrative password if you’ve made changes to the fingerprints that you’ve enrolled in Touch ID.
Using Touch ID on Mac
For unlocking and user switching
Touch ID can save you from typing your account password on the Login screen.
After the initial password-based login, you can authenticate with Touch ID instead of your password. As mentioned in the opening section of this article, Touch ID can be used to open locked System Settings features, the Passwords section in Safari preferences, and any password-protected notes in the Notes app.
And if your computer is set up for multiple users and each user account has Touch ID set up, you can use the fingerprint sensor to quickly switch to any logged-in user accounts via the Fast User Switching feature.
On the App Store and iTunes Store
For security reasons, your Mac may ask you to enter your password on your first store purchase or if you’ve made changes to the fingerprints that you’ve enrolled in Touch ID.

For Apple Pay on websites in Safari
Authorize your purchase by placing one of the registered fingers on the Touch ID sensor when a prompt appears on the Touch Bar. A check mark followed by “Done” appears when the purchase is completed.
Your bank may only display the transactions made from your computer, or you might see all transactions made from your credit or debit card account, including those made from all Apple Pay devices and your plastic cards.
Keep in mind that you might see different transaction amounts from locations such as restaurants, gas service stations, hotels, and car rental companies because some banks provide only initial authorization amounts to Wallet.
Touch ID troubleshooting tips
Your Mac’s fingerprint sensor does not work well with wet or oily fingers because moisture, lotions, sweat, oils, cuts, or dry skin might affect fingerprint recognition. Due to these technological restrictions, you’re likely to experience temporary hiccups with Touch ID after activities like exercising, showering, swimming, or cooking, including any other conditions or changes that affect your fingerprint.
You can clean your Mac’s Touch ID sensor the same way you would clean the display: either use a microfiber cloth to remove finger oils and residue or dampen a soft, lint-free cloth with water only, then use it to clean the Touch ID sensor.
Shut down your Mac and unplug the power adaptor before cleaning the sensor.

Delete enrolled fingerprints on Mac
As mentioned, your Mac can remember up to three different fingerprints. You can easily remove one of the enrolled fingerprints via these steps:
Enter Mac’s password and hit Unlock.
To use this fingerprint later, you’ll need to add it again there.
If your work is confined to being at home and the only way you’re able to interact with your colleagues and superiors is through video conferencing software, then your webcam is your best buddy during these tough times. However, unlike other tools of technology, webcams haven’t really made huge strides in quality.
But what if you already have a GoPro camera? Can you use it as a webcam for your meetings? The answer is yes, thanks to GoPro’s recent attempt to make its cameras work as your default webcam.
What do you need
In order to set up your GoPro Camera as a webcam for video conferencing, you will need to have the following items in check:
GoPro HERO8 Black camera
USB-C cable that came with your GoPro
A macOS machine (MacBook, Mac, or Mac mini)
A USB adapter/dongle if your Mac system doesn’t have a USB-C port
Your camera’s microSD card, adapter and card reader
How to enable a GoPro camera as your virtual camera on a Mac
Once you have made sure that you have all the items listed above, you can proceed to enable the GoPro Camera as your default webcam on a Mac.
Since the ability to use the GoPro as a webcam arrives through the latest beta firmware, you first need to update your camera software to get the functionality. To update to the latest beta build, download the GoPro Webcam Beta Firmware on your Mac and unzip the file which will create a folder in the name of the .zip file.
Now, insert your camera’s SD card to your Mac by placing it inside its SD card adapter and then inserting it into the native SD card reader. If your Mac doesn’t have an inbuilt SD card reader, you will need an external SD card reader to plug into the USB port. Once your micro SD is detected on the Mac, copy the extracted folder (extracted from the .ZIP file) onto the SD card using Finder.
To install the GoPro beta firmware, power OFF your camera, insert the micro SD card into the camera and then power it back ON. The camera will be able to update its software automatically and will beep during the installation process. Once the software is installed, you will be able to see a checkmark on the GoPro screen.
Note: In case the update failed, remove and re-insert the battery and then power ON the camera for allowing it to install the firmware again. Follow this support page for more details on the installation.
Download and install GoPro Webcam Desktop Utility on your Mac
After the beta firmware on your Go Pro is installed, you can now install the GoPro Webcam Desktop Utility on your Mac. You first need to download the GoPro Webcam Desktop Utility, open the “.PKG” file and follow the on-screen instructions to install the GoPro tool for your Mac.
Once the installation is complete, a new GoPro icon will appear in the Menu bar.
Setting up your GoPro webcam
Before you connect your GoPro Camera to the Mac, it’s important that you set it up right, so that it’s perfect for being used as your default webcam. Since a GoPro is known to have a wider field of view than most cameras, you can set it up nearer to you than your regular webcam. You can position it in front of Mac’s screen like on a desk or mount it on top of Mac’s screen using your existing GoPro mounts.
Additionally, you can purchase and use GoPro’s own accessories like the Jaws Flex Clamp, Magnetic Swivel Clip, Suction Cup, and Gooseneck to mount your GoPro in different angles and creative point-of-views.
Connecting your GoPro to the Mac
Now that you have set up your GoPro in position to be used as a webcam, you can connect it to your Mac using the USB-C cable that came with your Go Pro. After connecting the two devices, power ON your GoPro.
The GoPro icon in your Mac’s Menu bar will now display a blue dot to indicate that it has successfully established a connection with the GoPro.
At the same time, the display on your GoPro will also show the USB icon, indicating that it is currently in USB Mode.
Enable GoPro camera inside your video conference app
Now that you have enabled the GoPro as your webcam, it’s time to set it as your default video source inside the video conference app you use.
Here are steps to enable the GoPro camera as your default webcam in some of the popular video calling apps:
The above guide was for those of you who wanted an easy and simple setup solution of the GoPro Webcam on a Mac. You can also follow the tips mentioned below to make the most of your GoPro inside meetings and video conferences.
Change video resolution
Adjusting the Field of View using Digital Lens
The GoPro Webcam Desktop Utility comes with a Digital Lens feature which lets you change the Field of View of your webcam. The Digital Lens option will only be visible when your GoPro is being actively used as a webcam.
GoPro camera as webcam a Windows PC
Well, GoPro’s software supports only macOS right now. Hence, if you got a Windows PC, or any other OS, you can use your GoPro camera as a virtual camera on that.
