Good evening I'm having a problem with my iMac. A while ago, I used Open Core to install a newer version of macOS. It seemed to work, but then one day I got stuck on the Apple logo and the Start menu. I then realized I was in a kernel panic. Now I've also created a target disk to format the internal drive, because otherwise, even USB drives won't boot. With Open Core and installing Sonoma, I managed to install, but with problems. When I press EFI Boot, the USB drive goes black and reverts to the previous state. I install everything, but It freezes immediately. I read that you should install the latest supported version first. I create the USB stick but it doesn't work. It crashes in verbose with btex code, like "cpu/gpu unsupported." It tells me... What can I do? Because I'd hate to throw it away. submitted by /u/Icy-Requirement-3540 [link] [comments] [► Source]
