I installed dosdude1’s catalina patcher and it was working fine. Updated to catalina 10.15.5 which was working fine up to a few days ago. I have tried resetting the smc/pmu and zapping the pram. The 1st one doesn’t do much and the second not much either. By holding down apple +r keys on startup I can get to the recovery partition( dosdude’s version of it) . When I try and reinstall the os it gives me some message about certain components not being able to be downloaded, so reinstall of the os is not possible. I can’t seem to get into safe mode either. I have a 5,1 Mac pro, late 2010, 12 core, 48 megs ram and a sapphire radeon hd 7950 video card which has a switch on it, which is in position 2. Please help me... I’m lost and I’m stumped and for right now I’m up shhh.... creek without a paddle.. thx for any help/replies... John b
