High Sierra works on Apple's latest file system called APFS.

Apple support states that you should choose macOS extended when formatting your drive, and not the new file system, APFS.

Create an BackUp
Create a backup of everything you will/may need in a future. Use Time Machine or another application to backup your system. We recommend that you make two cloud and two physical (local or remote) backups. Also consider using drive cloning apps such as Carbon Copy Cloner, Super Duper, ChronoSync, or similar. These create an identical copy of your drive and, unlike Time Machine, are bootable backups (i.e. if your computer ever stops working, you can boot your computer directly from these copies).
Disable FileVault
FileVault encrypts the entire disk to protect against unauthorized access to data stored on your startup disk. People rarely use this feature, but you may need to check it out, especially if you log in in with your account password (FileVault requires password secured log in).

Your content will not be deleted from your device when you deauthorize it - you will simply deny permission to access protected content (which can be recovered anytime by re-authorizing the same device). Do not skip the deauthorize step, since if you sell your authorized device and later decide you wish to deauthorize it, you will be forced to deauthorize all of your devices and then re-authorize all usable devices again. This will be time-consuming and inconvenient.
How to deauthorize your Mac:
Open iTunes (login with your Apple ID if required). From the menu bar at the top left of your screen, choose Account, select Authorizations, and finally click on 'Deauthorize This Computer.' If required, enter your Apple ID and password and click Deauthorize.
Deactivate programs and remove authorizations
Many third-party applications require machine authorization and activation, especially image, audio/video editing, and software design packages. For example, most Adobe programs require activation. To activate an application, log in with a valid user licence. Deactivation dissociates an application from a valid user licence, so if you need to use the same application on another device, you do not need to uninstall - simply deactivate and use the licence on the other machine. Look up your programs list to find and deactivate programs.
