I installed Monterey on my imac a year ago. Imac 27, 2011, mod Nvidia Kepler. And it runs flawlessly, until two days ago, I updated to Monterey 12.6.3. After the update and reboot, was trying to post install patch with OCLP 0.4.7. And then a message popped up says new version of OCLP (0.5.3). So, downloaded 0.5.3, build opencore to my efi, and reboot. And, it won't reboot like how it was.
So, ended up trying new fresh install of Monterey, and no luck at all. The installation keep failing.
This is how:
press option key while boot, got into efi on USB, and install. The installation progress go until 10 minutes remaining, it goes to first reboot. After first reboot, select efi with grey HDD logo, installation continue and says 29 minutes remaining.
When the progress go until 12 minutes remaining, the second reboot came. After reboot, it automatically select the efi with grey HDD again, and the progress bar stuck at about 1 third, and then reboot again, go back to progress bar stuck at 1 third, and reboot again. Repeat and repeat.
I tried different USB sticks, different version of Monterey, and different version of OCLP, still no luck.
Any thing that I missed? It was working for a year, the latest Monterey I had before this was 12.6.2.
