Google is rolling out Memory Saver mode over the next several weeks, but not everyone will see it yet. Fortunately, if the new Settings -> Performance menu is not visible for you, you can activate it manually by using the experimental features in Chrome Flags.

Before you proceed, be sure to bookmark any important tabs and save anything important that you're working on in Chrome, then update the browser to the latest version available (109.0.5414.119 as of writing).

• Launch Chrome and paste the following into the address bar: chrome://flags/#high-efficiency-mode-available

• Next to "Enable the high efficiency mode feature in the settings", change the Default setting to Enabled, then restart Chrome

• Now paste the following into the address bar: chrome://settings/performance

• In the new "Performance" menu, toggle the switch next to Memory Saver to enable it

• Restart Chrome for the changes to take effect

Apart from Memory Saver, Google is also rolling out an Energy Saver mode that makes Chrome automatically limit battery draining tasks when the battery hits 20 percent. It does this by reducing its image capture rate and other background tasks, so you may notice changes in gaming and video performance.

The mode can be toggled on or off in the same "Performance" page in Settings. If you don't see it (this setting is only visible on portable computers) and don't want to wait for it to roll out to you, simply follow the same steps as above, but replace the address with chrome://flags/#battery-saver-mode-available and select Enabled next to "Enable the battery saver mode feature in the settings", then restart the browser.

Whether you’re wanting to stop receiving inbound AirDrop requests for files, trying to avoid a networking conflict, troubleshooting, or just limit your network footprint, it’s easy to turn off AirDrop on MacOS.

Turning off AirDrop in MacOS is the same in all versions of macOS and Mac OS X, regardless of system software version. Here’s how:

• Open the Finder on Mac

• Go to “AirDrop” in the Finder window sidebar, or pull down the Go menu and choose AirDrop from there

• Click the small blue text at the bottom of the AirDrop window that says “Allow me to be discovered by:” and select “No One” to turn AirDrop off

With AirDrop turned off you will not be discoverable by other devices that are looking for AirDrop destinations. This means you won’t be able to receive any files or data sharing requests from anyone via AirDrop.

If you’d like to enable AirDrop at any time, simply switch the AirDrop allowing options to either Contacts Only or Everyone, like so:

• Open the Finder on Mac

• Go to “AirDrop” in the Finder window sidebar, or pull down the Go menu and choose AirDrop
• Click the “Allow me to be discovered by:” text at the bottom of the window and choose “Contacts Only” or “Everyone”

This turns on AirDrop again and allows the Mac to be available for AirDrop requests. You will also need to make sure you have Bluetooth enabled on the Mac to be able to use AirDrop successfully.

Renaming a Mac is simple enough in macOS Ventura, but it is not obvious, here’s how it works:

• Go to the  Apple menu and choose “System Settings”

• Choose the “General” system settings from the side menu
• Click on “About”
• Look for “Name” and click on the text to the right of that to edit the computer name of the Mac, then hit Return or click away when finished

And there you go, you have changed the name of your computer in macOS Ventura. The change in the Mac computer name will reflect not only locally on the Mac, but also as it is identified to you and others through AirDrop, networking, and the computers hostname.

Apple has increasingly made it hard to mess with macOS system files. That’s true whether you intentionally want to extend macOS’s functionality or if a malicious party is trying to install and activate a virus.

However, many system components and all Apple and third-party apps rely on preferences and other files to store your custom settings, caches for work in progress, and other data. If those files corrupt, macOS may be perfectly fine, but you can’t get anything done in an app or your account.

Once you’ve gone through troubleshooting your Mac within your account that doesn’t seem to improve matters, the next big leap before reinstalling macOS is to set up a fresh macOS user account. From this account, you can test hardware, like your Wi-Fi or ethernet adapter; add printers and scanners; or run third-party software that keeps crashing on launch.

Because a fresh account typically contains nothing that would already be corrupted, you can isolate whether a problem is in your everyday user account or a system-wide issue–maybe even hardware related.

Here’s how to set up a fresh, new user account in macOS Ventura:

• Go to System Settings > Users & Groups.

• Click the Add Account button.

• Enter your password if prompted.

Here’s how to set up a fresh, new user account in macOS Monterey and earlier versions of macOS:

• Go to System Preferences > Users & Groups.

• Click the lock icon and enter your administrator password.

• Click the + sign at the bottom-left corner of the user list.

Then, after those first three steps in any version of macOS:

• Choose whether to create a Standard or Administrator account. Give it a name, password, and hint, and click Create. When making the account, what kind should it be?

Create a Standard account if you want to test a problem from the perspective of a user without any extra privileges.

Create an Administrator if that’s your normal account type–that’s typical–and you’re trying to perform an apples-to-apples comparison.

• Choose  > Log Out [name].

• At the login screen, select the new account, enter the password, and click the arrow to log in.

Now you can check if your problem persists. For instance, if you can’t get a Wi-Fi adapter to show up in your regular account, this new one should have a fresh set of adapters that represent all the hardware your Mac recognizes. It should pull those into the System Preferences > Network pane (macOS Monterey or earlier) or System Settings > Network view (macOS Ventura). If Wi-Fi doesn’t show up as an adapter in the list, it’s likely a hardware problem, though reinstalling macOS is the next step before a repair shop just in case.

When you’ve debugged your problem, you can get rid of the account. You must be logged in using an Administrator account to do this. (Warning! These steps are irreversible. Choose “Don’t change the home folder” to retain it.)

In Ventura, go to System Settings > Users & Groups, click the i info button next to the account, click Delete Account, enter your administrator password, and click Unlock. Now select “Delete the home folder,” click Delete Account, and confirm.

In Monterey, go to System Preferences > Users & Groups, click the Lock icon to authenticate, select the account you create to debug macOS, click the – sign at the bottom-left corner, choose “Delete the home folder,” click Delete User, and confirm.

AppleInternal is apparently used by Apple for internal development purposes, and thus likely has no benefit or reason to be installed on an average users Mac. Why it is included on some macOS installations with new Macs (and apparently some reinstalls too) is a bit of a mystery, since these are not Apple employee computers.

To delete AppleInternal from the Mac, you can open the Terminal application and issue the following command at the command line:

sudo rmdir /System/Volumes/Data/AppleInternal

Enter your administrator password and press Enter.

Then, you should reboot your Mac and the /AppleInternal directory will no longer be there.
