I just finished updating a rMBP10,1 mid-2012 from Sonoma 14.0 (23A344) + OCLP 1.2.0 to Sonoma 14.1 (23B74) + OCLP 1.2.0
I used the OCLP options to load up a 32GB USB key with Sonoma 14.1 installer and also installed OCLP 1.2.0 onto it. At the end of making the USB key I took the OCLP option to install macOS from the USB drive to the internal SSD
It all worked out OK. But I did get one occurrence of the progress bar stalling at about 30%. I think I groaned out loud at that point after recent experiences. Forced reboot and pressed the shift key to try going through safe mode. I didn't see any signs that safe mode was active. But the good news was no 30% progress stall occurred this time.
The m/c is running quietly (no fans) and all is looking good so far. And I didn't have to reinstall the root patches, it all "just works".
Another thing I did: Before updating I downloaded the KDK for Sonoma 14.1 (23B74) from the
Dortania Github page and pre-installed it into the /Library/Developer/KDKs folder. I dunno if that was necessary or not; I think I saw something about OCLP doing that for you when running the build step.
