Hmmm, I'm having some weird issues, and I wonder if I am the only one?
Based on what i've been reading, people have been updating to 12.6.1 without issue, but I have not been so lucky...
Today I updated my OC ver to 0.8.5, after confirming that it was fully stable and working fine, I decided to take the plunge and go for 12.6.1.
After Monterey was done downloading and doing the initial install, I clicked "reboot" -- the initial reboot didn't work, sadly, and every time I clicked "macOS Installer" (I tried 4-5 times) it just kernel panicked, so I decided "what the hell, 2nd time's the charm"
Re-ran the Monterey installer, then rebooted. Apple logo actually filled up! (very slowly, but it filled!) Then my cMP rebooted automatically, and I was met with the OC boot picker without seeing any macOS Installer -- which told me that Monterey successfully installed!
So I chose "macOS" and then..... Kernel Panic a few seconds into apple logo loading...
I decided to see if I could maybe reinstall it, so on the OC boot menu, pressed Space to bring up the recovery options, and there I saw it "Recovery 12.6.1 dmg" so I clicked, but unfortunately, now I am stuck with KP reboots.
I have a solid, fully working 0.8.5 config.plist, and I made sure to use AVXpel.
Typing this from Windows, since I'm unable to boot into macOS or the recovery.
I don't know if this is of any importance -- but I am due to reflash my bootROM. Was going to do it earlier today but decided to put it off to tomorrow, as I also want to take the time to clean the inside of the cMP, when I take out the 6800 and put in the 580 to use Mojave.
The method I used for updating to Monterey was #2 from the macOS section of the guide -- since I normally run OC with SecureBootModel = Default, I use hybridization, and my FirmwareFeatures are updated. Also, when I updated BigSur all the way up to 11.6.5 previously, it all worked fine.
I don't think there is any way to salvage what I currently have since I am instantly met with KP, but I think I will try doing a deep NVRAM reset tomorrow (highly doubt that will do anything).
Any thoughts or help is highly welcome
Thanks!
