Hello everyone. I will try to keep this as short as I can but I'm having a weird issue that I can't resolve. The problem: So, I'm getting stuck on boot. Apple logo comes up, loading bar is moving, gets up to 50-60% then stops. Once that happens, I get the spinning thing that gets animated for a while before it freezes completely. Sometimes, the apple logo and loading bar disappear and I can see the mouse cursor along with the spinning animation, but I can't move it. Unfortunately, somehow I managed to back up after the issue happened so I can't really restore. I can boot into recovery just fine. Things I've tried: Boot in Safe Mode Reset PRAM Re-seat memory Removed all PCI-Express cards and USB peripherals Ran fsck from single user mode, also repaired disk from disk utility. No errors. Some background: I had a GPU failure suspiciously the same period this problem happened. I replaced the GPU and while video seems to be working fine (e.g recovery environment) I'm curious if something regarding the drivers is now messed up. This machine had been kept running headless (no monitor attached) and I used VNC to log in. It has a static IP configured and shares two drives over the network. Weirdly enough, even at this stuck state the drives are still accessible on the same IP and I can still log in via VNC but only get a black screen. Conclusion: I really need to try and fix this without resorting on a clean install. I have configured many, many things on the system level and it would take weeks of work to get it back to where it was. I have not thought about doing a verbose boot and will do so very soon (not home atm) and hopefully get a better idea of the problem. Does anyone have any ideas about what to troubleshoot next?
