Choosing The Right Format

When erasing your MacBook Air 2015, it’s important to choose the right format for your needs. The two most common formats for Macs are Mac OS Extended (Journaled) and APFS.

Mac OS Extended (Journaled)

Mac OS Extended (Journaled) is the older format and is compatible with all versions of macOS. It’s a good choice if you need to use your hard drive with older Macs or with other devices that don’t support APFS.

This format is also a good choice if you need to store large files, such as video or audio files. However, it can be slower than APFS when it comes to copying files or performing other disk operations.

APFS

APFS is the newer format and is only compatible with macOS High Sierra and later versions. It’s a good choice if you have a newer Mac and want to take advantage of the performance improvements that APFS offers.

One of the biggest advantages of APFS is that it’s optimized for solid-state drives (SSDs). This means that it can perform faster than Mac OS Extended (Journaled) when it comes to copying files or performing other disk operations.

However, APFS may not be the best choice if you need to use your hard drive with older Macs or with other devices that don’t support APFS.

Which Format Should You Choose?

When choosing the right format for your needs, consider the following:

  • Compatibility: Will you need to use your hard drive with older Macs or with other devices that don’t support APFS?
  • Performance: Do you need the fastest possible performance when copying files or performing other disk operations?
  • File Size: Will you be storing large files, such as video or audio files?
  • Once you’ve considered these factors, you should be able to choose the right format for your needs.

Reinstalling macOS

If you have decided to erase your MacBook Air 2015, you will need to reinstall macOS to start using it again. Here are the steps to follow:

  • Restart your MacBook Air and hold down the Command and R keys simultaneously until you see the Apple logo. This will launch the macOS Recovery mode.
  • In the macOS Utilities window, select the “Reinstall macOS” option and click “Continue.”
  • Follow the on-screen instructions to reinstall macOS. You will need to select the disk where you want to install macOS and agree to the terms and conditions.
  • Once the installation is complete, your MacBook Air will restart automatically. You can then set up your MacBook Air as a new device or restore it from a Time Machine backup.

It is important to note that if you are using macOS Monterey or later, you may be prompted to enter your Apple ID during the installation process.

This is to verify your identity and ensure that you have permission to install macOS on your MacBook Air.

If you encounter any issues during the reinstallation process, you can check the Apple Support website for troubleshooting tips or contact Apple Support for assistance.
