Hmm, on the backup disk try changing SecureBootModel to Disabled and see if it will boot.

Thanks again for your help Casey. Unfortunately it’s already set to disabled.

Just for clarity’s sake:

M.2 Boot drive contains EFI, and macOS
USB-C External is an exact clone made with CCC and EFIclone.sh

I press F12 at boot and the following happens:

  • Choose M.2 partition, I can boot macOS from original M.2 or backup with no problem
  • Choose the EFI on the cloned drive, I can boot the original M.2 but not the clone
So for some reason, the cloned EFI will not boot the cloned drive. But every other permutation works flawlessly. So there doesn’t seem to be anything wrong with the EFI (as it boots the original M.2) nor the backup (boots fine from the original EFI)

Which version of macOS is this?

On Big Sur and Monterey we have to allow CCC to erase the destination disk as follows:

Just tried again with identical results. The EFI on the cloned drive will not boot the backup. I guess that's not really a problem as I have other backups of my EFI - As long as I can use one of those to boot the backup, then I guess it's ok.

I just did the same thing, but it works fine. Namely:
  • Connected Samsung EVO 850 2.5" SATA SSD to this Sabrent USB 3.0 Enclosure
  • Connected Sabrent enclosure to front panel USB 3.0 port on Z490 Vision D
  • Formatted Samsung EVO 850 SATA SSD in Disk Utility with:
    • Format: APFS
    • Scheme: GUID Partition Map
  • Cloned Monterey public beta #8 using latest build of Carbon Copy Cloner 6.0.3
    • Legacy Bootable Backup Assistant (uses Apple's APFS Replicator)
  • After CCC was done, manually mounted source and destination EFI partitions and copied EFI folder to the backup disk
    • Uses OpenCore 0.7.4 EFI configuration from this thread
    • This installation has System and Home folders on the same disk.
  • Rebooted
  • Pressed F12 at Gigabyte splash screen and selected external Sabrent disk
  • At OpenCanopy Picker, selected the external Monterey SSD
  • System booted up -- everything okay (but not as fast, of course)

Inspired by your choice of USB port, I plugged into the front USB port instead of the rear TB3 port and it worked just fine. Same with the USB-C (I have an extension to the back of the case as mine doesn’t have a front USB-C). Is there an obvious reason that i’ve overlooked why it wouldn’t work from one of the TB3 ports?

Try setting:
  • BIOS --> Thunderbolt Boot Support --> Boot Once

CaseySJ to the rescue once again. That did the trick! I’ve bought an M.2 and the Sabrent TB3 enclosure so that setting will definitely come in handy in the future. Don’t know why I didn’t think to try it. Thanks again Casey!
 
Speaking of Thunderbolt NVMe enclosures, I use the Acasis enclosure. It has Titan Ridge inside (jhl7440). So it can also function in non-Thunderbolt USB3.1 USB-c ports, albeit at 10Gbps not 32Ggbps. This is better than Alpine Ridge enclosures which in my experience are limited to functioning only in Thunderbolt ports.

I’m getting 2900 MB/sec read write via the Thunderbolt bus...with a bunch of other devices hanging off the bus as well via a hub. Not bad. I like the externalization of the PCIe bus via Thunderbolt.


There are various NVMe enclosures on the market, some cheaper than this, so choose whatever suits you. But having USB 3.2 functionality as a backup is a good thing too.

It claims to be USB4, so does it have Maple Ridge (JHL8540) or still Titan Ridge?
