I was able to scope out the conflicting item - a legacy extension that was perpetuated but wouldn't load - and since I trashed it, my clones have all booted successfully.īefore learning that I could create bootable clones, I tried to install Monterey on my external following Mike Bombich's instructions, and it hung, although I suspect that it would have booted had I known to trash that extension.Īs far as maintaining bootable clones going forward, they still serve their intended purpose with Intel Macs, but they aren't especially useful with M-1 Macs. After a couple of back and forths with Dave Nanian, he opined that it sounded like I was running into some sort of conflict, and suggested a safe boot which, lo and behold, was successful.


Unless there is a lot of interest on FineTunedMac I will in all probability abandon the project.I've got three CCC clones - 2 in separate containers on my internal drive and 1 on my external drive - and although I normally just ASSume that they're all bootable, I just experimented and successfully booted into all three.Īt first, I didn't realize that CCC could turn the trick, and I got involved with SuperDuper!, which claimed to have successfully created bootable clones, but I experienced the same dead-end hangs as you when I tried to boot into them. so I thought I would take a shortcut and ask you all.ĬONFESSION: To be honest, I am having trouble justifying a lot of effort on something that my past history indicates will seldom if ever, be necessary or used other than as a curiosity.

Has anyone been able to INSTALL a bootable copy of Monterey on an external drive?ĬONFESSION: To be honest, I am having trouble justifying a lot of effort on something that my past history indicates will seldom if ever, be necessary or used other than as a curiosity.Have you had any success creating a bootable Monterey CLONE using CCC or SuperDuper?.I have formulated a testing plan to isolate the cause of the failure, but it would take a lot of time and energy, both of which are in short supply at the moment, so I thought I would take a shortcut and ask you all. I have used CCC to create bootable external clones of Catalina and Big Sur in the past, but although I know that I created a Monterey clone before, I don’t recall if i ever actually booted it. I tried booting from the external drive three times with the same results. The boot process appeared to go normally up to a point - and then hung and never continued. Everything went according to plan until I attempted to boot from the clone. As a part of the CCC testing, I attempted creating a bootable clone using and the "legacy cloning" process, which I had done successfully several times in the past. To make a long story short, during the process, I downloaded the latest Carbon Copy Cloner update, CCC 6.1.1 (7323), and re-ran all my various CCC tasks to be sure the drive configurations were recognized and working. As part of the process I re-configured my various external drives and devices and I have been testing various applications mostly to be sure the various registrations, etc. I am almost finished transferring to a new Apple Studio and updating it to macOS 12.4.
