Procedure to create bootable backup :-
- Erase/Format Target drive using Disk Utility, ensure you use GPT partition scheme, select HFS or APFS
- Clone existing MacOS partition to Target drive using Carbon Copy Cloner or Super Duper
- Mount Source EFI partition
- Mount Target EFI Partition
- Copy EFI folder form Source to Target using Finder
I believe I correctly followed these steps (used Super Duper), but when I open EFI Mounter, it does not give me an option to mount my target drive's EFI partition - the app doesn't see it?
Target drive is 1 of 3 partitions on a 2TB External USB SSD. The partition container disk is an APFS Container (disk5), and the partition itself is an APFS Volume (disk5s1).
No disk5s1 showing in EFI Mounter:
Where did I go wrong?
UPDATE:
Okay, so EFI Mounter still does not see my target EFI partition . . . but I see a new EFI partition mounted on my desktop and showing up in finder.
I copied contents of one EFI partition to the target partition and I was able to select my USB drive's UEFI partition at bootup and get into Clover! . . . but how do I know which one is my external drive's Mac OS?:
This took me to a screen that looks like when you are installing the OS and you want to use disk utility.
This one didn't work - got the black screen with the white circle with a cross through it (no bootable drive).
Haven't tried this one, but doesn't seem right.
Boot macOS from Mojave is my primary SSD drive hackintosh - not the backup.
Also haven't tried this one but also doesn't seem right.
I'm getting to this Clover screen by booting off my external USB drive, but which one is the bootable backup on my external usb drive? None seem to be the obvious choice. The only ones I haven't tried are the second and third from left to right - is the firevault prebooter or install prebooter my backup?
