This guide is for upgrading to a new SSD, restoring from Time Machine and keeping your Recovery Partition.
The first time I tried to install a new SSD I just installed the SSD and didn't format anything. I figured the format would be chosen by MacOS but it wasn't and the recovery partition didn't copy over to the new disk. If you don't have a Recovery Partition you can't use Disk Encryption or Find My Mac.
Note: you may have to disable/remove disk encryption but my Disk wasn't encrypted so I don't have steps for that
- Do a Time Machine Backup and make sure you're not excluding anything you need
- Shut down your Mac and go through the process of removing the old drive
