Installed Sonoma on a MacPro 4.1 (Early 2009) - everthing looks good. Today when I was configuring update in the system setting the system stopped for some time until I finally was able to quit system settings. After a reboot the system behaves very strange - during startup the sonoma landscape increased brightness in slow steps. After startup the desktop was in white with very bad readability / poor contrast (instead of the sonoma landscape shown before) and reacts slow and stuttering to mouse movements. It was impossible to change display settings. The system is nearly not usable anymore.
I had this issue before - tried to reinstall the system using the same installer stick I used to do the first install but get an error message that the system is newer than the installer. Then used Carbon Copy Cloner to transfer the SSD to another one, but the copy does not start. But on the copy I was able to reinstall the system using the same installer stick and install Open Core Patcher again and got it working untill todays problem occured again.
My question - does anybody observed similar issues ? Any Idea to avoid that ? A better fix instead of CCC / reinstall .. ? Already tried the usual things like resetting PRAM ..
