Your computer will feel as though you just took it out of the box by executing a factory reset after making a Time Machine backup and backing up your MacBook Air.
Now that macOS Mojave is out, now is the ideal moment to update your computer once more. Your Air will continue to function properly for many years to come thanks to the numerous new improvements and system modifications in Mojave.
However, keep in mind that only MacBook Airs produced after mid-2012 are compatible with macOS Mojave. To make sure that all of your data is backed up and the reset is done correctly if you’re not familiar with how to perform a factory reset on your MacBook Air, follow the steps listed below.
Backing up Your Data with Time Machine
On a MacBook Air, Apple makes data backup quite simple. You can back up all of your files, programs, and other crucial data with a Time Machine and an external hard drive.
It’s a fantastic opportunity to purchase an external hard drive if you don’t already have one. Built exclusively for Time Machine backups, Apple offers the AirPort Time Capsule.
In addition, there are many 1 and 2-terabyte drives on Amazon for under $100. If you’re looking for a recommendation, look at the Seagate Backup Plus drive or the Western Digital MyPassport drive, both of which are built to function with macOS right out of the box.
1 Connect your external drive to your computer and launch the Mac’s Time Machine program (this is accessible either through Launchpad or in System Preferences).
2 Select your external hard drive by clicking Select Backup Disk.
3 Choose Use Disk, and your hard disc will be used as a time machine backup drive.
4 From the Time Machine menu, pick Back Up Now.
5 Select the Options option under System Preferences in the Time Machine menu to manage what is and isn’t being backed up (If this is your first time doing a Time Machine backup, it may take a while).
Once your backup is complete, please be sure to carefully remove the drive from your MacBook Air before unplugging it.
Open Finder and tap on the name of the drive to properly eject your external hard drive. Select the “Eject” button (an arrow with a line underneath). If your MacBook won’t let you do this, your external hard disc is probably still being used by another program or the backup isn’t complete.
Factory Resetting Your Mac Book Air
It’s time to factory reset your MacBook Air once you’ve backed up your user data to Time Machine or the backup program of your choice. You can use this procedure to fix the majority of defects and issues with your MacBook, such as slowdowns and frozen applications.
Resetting your computer will usually increase its speed to the level it was when you initially received it. To completely erase any user data still present on your MacBook Air before selling it, you must do a factory reset.
Redownloading MacOS from inside the boot display on your computer will enable you to wipe and reinstall the operating system using the built-in recovery disc utility.
As an alternative, you can decide to download macOS Mojave to your device from the Mac App Store and turn the downloaded file into a bootable USB drive. For that, you may find instructions here.
But for the time being, we’ll focus on how to restart your MacBook Air from the device’s boot screen. Please be aware that a working internet connection is necessary for this.
1 Click the Apple icon in the upper-left portion of your MacBook’s screen.
2 Select Restart from the drop-down option, then has your keyboard ready to start typing.
3 Press and hold down Command + R on your keyboard until the Apple logo reappears on your MacBook Air’s display. Hold on to the mouse until the macOS utility window appears on the screen.

4 However, click Disk Utility at the bottom of the list to factory reset your device.
5 Locate and pick your MacBook Air’s Startup Disk on the left side of Disk Utility when it has launched. This is the primary and only disc listed for the majority of users.
Inside Disk Utility, click the Erase button.
Choose Mac OS Extended from the Format pop-up window.
You can confirm your erasure by clicking Erase after giving your reformatted disc a name.
A display will now start to delete the drive and data on your MacBook Air. Your disc will be successfully wiped when this process is finished, but you are not finished yet.

How to Reinstall macOS on a MacBook Air
1 Start by exiting Disk Utility on your recently reset MacBook Air by choosing Disk Utility, then Quit.
2 To reinstall the most recent version of macOS, choose Reinstall macOS from the list of macOS Utilities and follow the on-screen instructions.
3 Select the default drive when prompted to select the disc you wish to install, as most MacBook Airs only come with one storage drive pre-installed unless you add another yourself.
4 Your computer will start downloading macOS when you click Install, following which you might be prompted to grant some rights. It will take some time for this download to complete, especially if your internet connection is sluggish. Wait patiently for the reinstall to finish. Be cautious to give yourself enough time to reset the system and resume working because this could take many hours.
5 You might need to manually begin the installation of macOS after the download is complete by agreeing to the installation on your machine. The macOS Welcome page will immediately boot up after your laptop has finished installing your operating system, asking you to create a new account and set up your system.
