What to do before you sell, give away, or trade in your Mac
Factory reset of your Mac - Apple Support
If the model you own is from Late-2011 or later, then you can use Network Recovery:
Internet/Network Recovery of El Capitan or Later on a Clean Disk
If possible, back up your files before proceeding.
You will need a fast, working Internet connection, preferably, Ethernet. If you must use Wi-Fi, you will be asked to select your network and enter the network password. This procedure will install the original version of macOS that came pre-installed from the factory.
