iMAC 2020 does not boot successfully from Acronis TrueImage 2021 Bootable Rescue Media
I am required to restore a unbootable Catalina based iMac 2020/2021.
When trying to boot the "broken" iMac from the newly built Resue Media(USB), I am asked to perform a software update ("a software update is required to use this startup disk").
This does mean connecting the Mac in question to the internet and waiting quite a long time.
After this unexpected update was applied, I tried to boot (Command-R) the "brocken" iMAC with the ATI Bootable Rescue Media (USB), but ATI is never successully loaded (only the Apple logo is shown and a never ending progress bar)
What am I doing wrong?
Thank you very much for any feedback!
The original USB-stick with the ATI Bootable Rescue Media was erased after making the first backup-image, and the actual ATI Bootable Rescue Media USB stick was built on an different MAC.
Yes, booting from external sources is enabled on this T2 based iMac :)
