I have a Late 2012 Mac mini (quad core i7; 16GB; 500GB SSD), running OCLP 1.1.0 and Sonoma 14.0. I never tried betas, nor the nightly builds. My goal was to do the OTA upgrade to 14.1 in place. At first I tried reverting root patches, but couldn’t download the update (not via Ethernet nor wifi) so I reapplied the root patches and was able to download and install.
I got to the reboot phase of the installation, and (having Verbose mode on), things seemed to go into an endless loop with a failed Setting BTCoex Config. This is a wifi module failure, so I guess the existing patch hadn’t carried forward and somehow it got stuck in the loop.
I let it run for quite a while since sometimes the screen would flash a longer message, but eventually gave up and powered off (hard reboot via power switch). A quick power on reboot showed the same behaviour.
So I next did a power cycle reboot, pressing Shift key to boot into Safe Mode. That took a while, but it finished booting. The About This Mac showed 14.1 so I figured the installation was finished. I then used OCLP to re-do the post-install root patches and that showed that there were two things waiting, including the wifi and graphics. I ran that, rebooted and things seem to be working again.
I created this account to share my experience, which is related to yours, but also to thank the Devs for a really amazing thing. I have been playing around with this on my old Mac mini for the past few weeks, first getting Sonoma running under 0.6.8 and then following through with the updates. Incredible effort, and a great job. Much appreciated and thank you. I hope my experience report is useful to others.
