Monterey update on unsupported Mac with OCLP - some questions

Monterey update on unsupported Mac with OCLP

I ran into some questions/issues with my update of macOS Catalina on a Late 2013 27” iMac (14,2) to Monterey 12.3.1 using OCLP 0.4.3. I’m not sure if the ‘’Nvidia Kepler’ post-install patch’ worked properly and I’m not sure if my display needs some correcting. I’ll list my questions at the end.


I carefully followed a combination of different YouTube tutorials since no one tutorial dealt with that exact combination. Everything seemed to go fine, although during the many reboots of my Mac during the Monterey install the on-screen icon options only appeared briefly and automatically moved on to the next booting stage without any intervention from me. Nonetheless the installation proceeded without any alerts and I ended up with Monterey and all my folders, files and apps. So the OCLP 0.4.3 seems to automatically handle the selection options during the various reboots.


I installed OCLP to my Mac’s Boot Drive EFI partition and ran the ‘Post Install Root Patch’ which only showed a single ’Nvidia Kepler’ patch. I installed that patch and rebooted. My iMac seemed sluggish on boot up but I put that down to Spotlight indexing etc. Once everything settled down it seemed snappy enough.


But my Menu Bar is not transparent, although it does seem to vary in colour across the bar that seemed to match the Monterey default Desktop and the Dock follows a similar pattern. Not being familiar with Monterey I opened OCLP again and ran the Post Install Patch which again showed the ‘Nvidia Kepler’ option, which I presumed would have disappeared following the root patch install. So I took some advice from a YouTube tutorial and ran the ‘Nvidia Kepler’ patch again. On a reboot nothing seemed to have changed and running OCLP again showed the same ‘Nvidia Kepler’ post install patch listed and not greyed out.


My Questions:

1. Is that display I described consistent with a successful ‘Post Install Patch’?
2. Should the ‘Nvidia Kepler’ patch remain in the OCLP options even after the patch installation?
3. Is there a definitive test to confirm successful installation of the Post Install Patch(es)?
4. ‘Universal Control’ does not work for me even though my iPad OS is 15.4.1. I know it’s listed by Apple as for use with iMacs 2015 onward, so could this be a hardware issue?
5. My Login Screen icon seems much bigger than in Catalina. Is there a way to modify that?

Thanks!
