I just updated my Mac Pro 5.1 from Sequoia 15.7.3 to 15.7.7, using OCLP 2.4.1.
I started the update from the system (Software Update).
At that point, OCLP launched and downloaded something.
Then the restart took a while, and I was a bit worried because my Mac seemed to get stuck at the beginning of the progress bar…
🙂 But after about 10-15 minutes, it continued!
So don't panic, just wait!
Once I got to the session log, the colors were off because macOS had cleaned up the graphics files.
OCLP offered to redownload them, and everything is working perfectly now.
Voilà !
