What's the best method for you to get rid of your M1-powered Mac? What should you do with the device if you still have personal data on a Mac? We're here to assist, so don't worry.

All of your personal information is saved on your computer and any external storage devices you may have. The computer's hard disk will store all of your emails, contacts, files, and other sensitive information that you don't want to share it with others.

Hackers are especially interested in obtaining data that may be used to get access to passwords or your identity. To guarantee that your old computer's data cannot be read by anyone else, it's a good idea to have it safely deleted from your hard drive before you throw it away or sell it.

The steps to wipe internal HDD/SSD on M1 chip Mac

Make a backup of your Mac data

Make a copy of your Mac or do a backup on it first. In order to reset a Mac back to factory settings, all of the data on the system is wiped off. Stay away from the trap that we were sucked into.

It wasn't until after we'd deleted the Mac that we discovered that the data for one non-Apple program we used wasn't in the cloud, even though we use iCloud to sync everything across all of our Apple devices, so we figured we could simply restore everything from the cloud.

Unfortunately, iCloud does not currently allow you to back up your whole Mac to the cloud. Fortunately, backing up your Mac is simple if you have an external hard disk to utilize. To accomplish this, just use Apple's Time Machine backup utility.

Apple's free Time Machine software or an application like AweClone for Mac or SuperDuper may be used to produce a clone of the whole hard disk.

Log out of everything

Apps that need an account may be found on several platforms, including Facebook and Twitter. Take iMessage and iCloud as two examples: they're both free. Log out of all of your applications. Reselling or getting rid of your Mac is very important. Each app uniquely implements this. The procedure for iCloud is as follows:

  • Go to the top-left corner of your screen and choose the Apple icon.
  • Select the System Preferences option.
  • To access iCloud, choose Internet Accounts from the drop-down menu.
  • Turn off "Find My Mac" in the Finder.
  • In the side panel, click Overview.
  • Upon completion of the procedure, choose Log Out to exit.
