Using Clover Configurator successfully clones the EFI from one drive to another but the problem I discovered is that what you get is identically named EFI drives on the startup and its confusing. It should be intelligent enough to recognize the target drive's unique name?

Using Disk Utilities, I was able to delete this unwanted blank partition and then I rebooted and all appears well? Thank you so much! This is so technical I have to be careful how to proceed. Brand new to MacOS Ventura too! I had no knowledge of what is a Preboot prior to this! Thanks!

I mounted the partition/volume and it appears to be... empty? I realized that I've never actually looked inside before? it just suddenly appeared in Disk Utilities when I was trying to work with another volume at the time. As since I'm currently using that volume I hope it will be safe to...

here's the terminal readout?

Well, yes, it's currently unmounted but I am pretty sure it will show up again if I reboot?

Although I'm aware of a 2018 discussion thread on this topic with various solutions, it's so technical! And I'm not sure if it applies to my situation, which is... A preboot partition has been accidentally revealed on the desktop via Disk Utility on a backup Monterey drive I wasn’t using (I was...

Thank you so much for all your words! I did succeed going from Mojave to Monterey but avoiding Migration Assistant by doing it as an MacOS Installer upgrade. But in this circumstance I'm not going "up" to another OS, all apps and settings after using Migration Assistant will be the SAME, so I'll...

Thank you so much for replying. This is a brand new Samsung 970 Pro that I bought so that it would become the primary drive. I am working off an brand new Samsung SATA that is supposed to become the backup drive. I did have previous "standard backups" from previous efforts with SuperDuper and...

Just attempted my first CCC Legacy Bootable Copy of an erased NVMe inside an PCI-E card and after just 13 seconds, it FAILS for reasons I don't immediately understand. The troubleshooting suggests that the drive must be a Thunderbolt or USB connecting drive. Is that important? Can't it be an...

Although I did succeed adding an EFI file (I ended up just building and installing OC to the drive, and using Clover Configurator I could SEE that the files are there) what I've now discovered is that my backup drive is not (yet) bootable. It's not recognized in Startup Disk as an OS drive...

yes, I'm using SD 3.8 and it's Monterey 12.7.1 I'm using OC 1.30 and yes, I'm using your latest EFIClone.sh I've just done an new erase of the backup drive (to become primary) and a new CLONING with SD without the script, I attempted to build and install OC into that drive and it hasn't worked...

Sorry, you've lost me -- I'm on a Mac Pro 2012 also known as Mac Pro 5,1 and I have to use OpenCore Legacy Patcher because this machine can only officially be run on Mojave without OC and I can't stay in Mojave as certain software already "knows" it's old and being deprecated, so I have upgraded...

yes, indeed I use a PCI-e card to mount the NVMe -- that's what I want to run from (I did it via Mojave) and currently I'm using a PCI-e Samsung SATA running the same OS...

I have the Mac 5,1 3.33 Ghz 6 Core Intel Xenon, running Monterey 12.7.1, I don't have a built in USB 3.0 -- I'm using that via an PCI-e Card (StarTech) which has 4 ports. No, Mojave is the OLD OS that I upgraded from and TO Monterey. I opted not to go Sonoma for now. I cloned Mojave, and ran...

How can I just ADD an EFI file to the backup drive as since I’m not successful (yet). I know there are tools where I can just mount the EFI and copy over to the other one but I don’t want to make mistakes. I actually made this attempt and when I rebooted with the Option key down, what I saw was...

I ran Carbon Copy and this was the error result: **** Task: CCC Backup Task Start time: 2023-12-17 17:13:55-0800 Error codes: 3195 : 0 : 0 Error: The postflight shell script exited with a non-zero exit status Advice: Verify that you can run the script manually without errors, and that...

This is becoming an epic! LOL! I moved the clone drive to the internal PCI-e card so there's no longer an external source. The error result is... | 04:38:32 PM | Info | EFIClone Script | 04:38:32 PM | Info | SuperDuper | 04:38:32 PM | Info | Dry Run (Y) | 04:38:36 PM |...

Presumably if I tried to use CCC to do the EFI cloning with my external USB/NVMe drive, that may fail too? It really has to be internal? I'll go that route and mount it to my PCI-e Card and do it properly!

Oh okay, I see what's happening. In all these attempts at cloning, I decided to use an external USB drive that contains my Samsung NVMe SSD and it's connected to the back of the Mac Pro via my USB 3.0 PCI-e card. I opted to do it this way because my (old Mojave OS) is currently using the PCI-e...
