I've got a 2015 era MacBook Air and want to wipe it and install the latest available Mac operating system on it. Can you help?
Sure, to wipe your MacBook Air and install the latest available Mac operating system, you will need to follow these steps:
Back up all of your important data and files to an external hard drive or cloud storage service.
Start up your MacBook Air in Recovery Mode by restarting it and holding down the Command + R keys.
Select "Disk Utility" from the Utilities menu, then select your startup disk (usually named "Macintosh HD") and click the "Erase" button.
Exit Disk Utility and return to the main Recovery Mode menu.
Select "Reinstall macOS" and follow the prompts to download and install the latest version of macOS.
Once the installation is complete, your MacBook Air will restart and you'll be prompted to set up your computer as if it were new.
Please note that your Macbook Air 2015 will only support up to macOS High Sierra 10.13.6, and that you can't install the latest versions of MacOS (Catalina, Big Sur) on that device.
