Hi everyone. I'm new here. I have just installed dosdude1's High Sierra Patcher on my 2008 Mac Pro 3,1. The Patcher installed fine, I managed to run the installer, then that completed and went to reboot (as it should have). My issue is that now the machine seems to try to boot up, but shuts off half way through. Before the startup chime.
I have never experienced this issue before and the machine has only had a month of use since I purchased it from Macbank on eBay.
I have tried cmnd-option-p-r and cmnd-r. These get me as far as the chime sound, but it ***** off shortly after, without my Acer monitor detecting a signal.
Is there anything I can do to fix this? Please help!
