Installation: Format NVMe drive.
- The Catalina installer should boot up and give you a menu of options.
- Select Disk Utility
- Format the NVMe drive by “View > Show All Devices,” select the drive (not the partition)
- Give your boot volume a name
- Select APFS format
- Specify GUID Partition Map
- After it is formatted, quit and go back to the Installer Menu.
Installation: Install Catalina
- Select Install mac OS, select your volume to install upon, agree to everything you’re supposed to agree to, then allow the installer to do its thing. The computer will restart.
- The USB Installer stick should still be inserted, and when the Clover bootloader appears, select “Boot macOS Install Prebooter from Preboot” and hit enter. Let the installer continue. The computer will restart.
- When the Clover bootloader appears, select “Boot Filevault Prebooter from Preboot” and hit enter. Installation will finalize, and you should enter the Catalina welcome process.
- During all the options, it is best not to sign into iCloud yet. You can do this later. I think it’s best if you get everything running, then once you are satisfied everything is OK, then you can set that up.
- Once all the options are selected, you should emerge on the other side into the Finder.
