I recently had an issue where my iMac would get stuck on the gray screen with the spinning thing whenever I had to restart. I couldn't even boot into safe mode. So I did the first thing you're supposed to do in situations like this I shut down the iMac and unplugged all external peripherals except for my keyboard and mouse then tried restarting again. The computer restarted fine after that and also seemed to be operating smoother then recently. So I then proceeded to plug in all my external peripherals one by one in hopes of identifying which one was causing the problem. I have a six port USB hub plugged into one of my USB ports which itself has three devices plugged into it. Ultimately I wasn't able to identify which peripheral is causing the problem and was suddenly able to successfully restart my iMac with everything plugged in. However I had changed which ports I was using on the USD hub.
So my question is could the problem have stemmed from one of the ports on the USB hub that I'm no longer using? Can ports on USB hubs start to go bad and cause problems like that without the whole hub being ruined?
My first guess was one of the three external hard drives I have connected to my iMac but that doesn't seem to be the case so this is the only thing left that I can think of. Any help would be greatly appreciated.
