Installed on my 2018 MBP without issue. Installed on my 2020 BTO i7 27" iMac, and appeared to install fine but on reboot.... nothing. Eventually goes to internet recovery endless loop.
- Tried safe mode: didn't work
- Tried target disk mode: acted normally, but no volumes show up
- Tried Revive: Acted like it worked, but just went into endless internet recovery loop
Appears that there is no Mac disks at all now - no main partition, no recovery partition, nothing. Interesting that in revive mode with configurator, I can see the boot camp partition which still works fine (and is how I'm typing this) but the Mac side seems to have been obliterated. I wouldn't be too concerned, but there's a couple files I'd really like to recover. Any way to at least access or restore the file system at least to recover my stuff? Any chance that internet recovery mode will get fixed to address this? (Curious as to root cause of this issue too - especially since both the regular and restore partitions are not visible)
