Restoring a Time Machine Backup on an Ecrypted Drive in Recovery Mode
Hello
2018 15" Macbook Pro
Mojave 10.14.2
I have done a Time Machine Backup to an external hard drive.
My Macbook Pro is being taken for repair soon and so the internal hard drive may be erased during the repair process and I want the ability to restore to the Macbook from the Time Machine backup on my external hard drive.
I know that to do this, you must enter recovery mode and choose to restore from the Time Machine external drive.
The issue is this: before I created the Time Machine backup on this external drive, I formatted the drive as "Mac OS Extended (Journaled, Encrypted)" and encrypted the drive with a password for security reasons.
This means that any time you plug the drive in, the computer asks you to enter a password to unlock the drive.
NOTE: I don't just mean that I encrypted the Time Machine backups. I mean actually encrypted the drive itself using Disk Utility. I did also encrypt the Time Machine backups however (by selecting "encrypt backups" within Time Machine)
My concern is about how this password encryption might affect the ability to access/restore from the external drive when I am in recovery mode. In recovery mode, I have never seen a Mac system prompt the user to enter a password to access an external drive and I wonder is that because recovery mode does not have the ability to access encrypted drives. If that is the case, then I might not be able to restore from the Time Machine backup on this external drive.
If anyone has experience with this, I would be grateful for your advice
Thanks
