Back up your Mac
From the very beginning, you'd better create a backup of the old Mac. If you find some important files on the old Mac lose, a backup gives a chance to restore it. Indeed, backup is the best way to avoid data loss.
Time Machine is Apple's built-in program. It is reliable and safe to use. To back up Mac with Time Machine, you need to prepare an external drive with compatible files system to store the backup data. It also helps to restore files from Time Machine when necessary.
Besides, you can use iCloud to sync your important data. Head to Apple menu > System Preferences > Apple ID, and enable iCloud for the desired app such as notes, contacts, and more. Or sign in to iCloud.com in a browser, then upload important files from the Mac to iCloud.
Sign out all accounts
Apple ID keeps your settings and Apple services up to date on all of your devices. To keep your personal information safe when you prepare Mac for sale, you need to sign out all the accounts with Apple ID signed in to deauthorize the computer before you sell your Mac to others, including iTunes, iMessage, Music app, iTunes Store, Apple Store, etc.
NVRAM is a small amount of memory in Intel Mac, storing all the Mac settings' information. Resetting NVRAM will clear user settings from memory and restore certain security features that might have been altered.
To reset the NVRAM of Mac, you just need to shut down the Mac, press the power button and simultaneously hold down the Option + Command + P + R keys for about 20 seconds, then release all the keys.
Note: If you have an Apple M1 Mac, you don't need to reset NVRAM by hand as it auto-resets if necessary at every time your Mac startup.
Unpair Bluetooth devices
This is an optional step. If you sell your Mac to a roommate or someone living within the range of Bluetooth, you should unpair all Bluetooth devices before that. In this way, you can avoid the Mac accidentally connecting to the devices that you are keeping.
It's easy to unpair your Bluetooth devices such as keyboard, mouse, trackpad, AirPods, etc. Navigate to Apple Menu > System Preferences > Bluetooth, and click the remove (x) button behind the names of paired devices, then click Forget Device to make a confirmation.
