Performing a factory reset on any of your technological equipment is sometimes advised as a fix for a variety of potential problems. This activity can be carried out to improve performance and return your MacBook Air to its former splendor.
A factory reset will make sure that all of your private and personal information is erased from your MacBook Air if you decide to sell it to someone else. In order to maintain good seller ratings and avoid the inconvenience of having to erase your information after the transaction is through, be sure that someone else can log in and start using your old MacBook Air.
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.
Resetting a MacBook Air or MacBook Pro
1. To start the Mac, hold down the Command and R buttons on the keyboard. When the Apple logo appears, let go.
2. Choose a language, then proceed.
3. Click Continue after selecting Disk Utility.
4. From the sidebar, select your startup disc, which is by default called Macintosh HD, and then click the Erase option.
5. Select Mac iOS Extended (Journaled) from the dropdown menu and then click Erase after deciding on a name for the disc once it has been erased. (Select “Journaled, Encrypted” if you want to encrypt your disc for added protection. You will be asked to set up a password.) Consider using GUID Partition Map.
6. Click Done and then Exit to close the window.
7. If you haven’t already, connect to WiFi in the top right corner of the screen the same way you would on a Mac.
8. Select Reinstall macOS from the main menu, then click Continue.
9. Click on Continue. There will be a pop-up window; select Continue there as well.
10 Click Agree after reading the software license agreement.
11. Click Install after deciding on your boot disc.
12. Attend the installation’s opening phase. (Now would be an excellent time to stop and stretch your legs. Sandwiches are recommended but not required.)
13. After restarting, the computer, installation will resume.
Establish a Backup
Make a backup of the MacBook Air before you start, particularly if you intend to use it again or transfer your information and documents to a new Mac.
Time Machine, a preinstalled Apple tool that backs up your stuff, including music, images, and apps, to an external drive, is a popular method of securing your data. Here’s how to use Time Machine to make a backup:
- Connect a Mac to an external storage device.
- In the top-left corner of the screen, click the Apple icon.
- Select System Preferences.
- Press Time Machine.
- Select Backup Disk by clicking.
- a picture of the settings for Time Machine
- Select your external drive, then select Use Disk and Encrypt Backups.
- If the ON button in the Time Machine window’s left column is not already selected, click it.
A backup of your MacBook Air is started by Time Machine after you click Use Disk or ON. You can later restore this backup by connecting your external hard drive to the Mac and following the on-screen directions after your MacBook Air has been returned to its factory settings.
Most MacBook Air users are often advised to utilize Time Machine, however, it is limited in what it can do. A bootable clone of your MacBook Air is something you’ll need if you want your MacBook (or another MacBook Air) to function exactly as it did before, even though it copies your files and apps.
As a result, you may want to think about using a free backup tool from a third party, like SuperDuper or Carbon Copy Cleaner.
