If you need to reinstall the operating system follow "How to install macOS" from the Apple Support documentation.
- Following this guide from Apple reboot into the system utilities and completely wipe the hard drive and reinstall the operating system. This guide use this step:
On an Intel-based Mac, if you use Shift-Option-Command-R during startup, you're offered the macOS that came with your Mac, or the closest version still available. If you use Option-Command-R during startup, in most cases you're offered the latest macOS that is compatible with your Mac. Otherwise you're offered the macOS that came with your Mac, or the closest version still available.
- When the format utility for erasing the hard drive prompts for name for the drive, I name it
MACHD
during the reformat process, and the format isAPFS
. Please note, I turn on filevault after the full reformat to keep the drive key synced with iCloud, and SSD type drives do not have the option to zero out like older drives. - Once the drive is reformatted, reinstall macOS using your home network, and iCloud account. I also allow my Apple ID to reset my workstation password.
- Under

andAllow my iCloud account to unlock my disk
. - Open the disc utility and if you notice an internal volume named
Update
delete it via this guide from Apple, then restart the computer. Please note, this may also cause a warningIncompatible Disc
to be displayed. If this occurs, you will need repeat steps 1 through 5 following this video walkthrough. Once these steps have been completed you should be successfully connected to your wifi. - Under the

are both checked. - Click
Show Updates
and run all pending updates. - Install the full
Xcode
developer package from the Apple App Store. I use the full package because it comes with both the gcc compiler and emulators for iOS devices. These come in handy for testing responsive websites and applications. Please note, this will require the latest version of the osx operating system, and ifFileVault
has not finished encrypting the hard drive you will have to wait for that to finish. The status can be located underSettings and Privacy
