I got help from here when I was installing Ventura on my Pro earlier this month, so I figured I should return an input. After installing, my macbook with 8 GB of RAM and 2.7 GHz Intel Core i5 got too slow, although it could now install many softwares that only supported newer mac os's. I tried booting in safe mode, resetting NVMe, etc., but the Activity Monitor showed that WindowServer was using too much CPU whatever I do. So I just erased the disk again and installed High Ventura (OS 10.13) via internet recovery. Now, it's fast and I am only installing softwares that support my OS. I'm much happier about it than when I had Ventura. I might have done something wrong but I failed to debug and I could not stand the slow-down. Hope this helps anyone who is looking to use OpenCore Legacy Patcher to install later OS's.
