iMac Not Liking 4 Port USB Hub
So I've been using an Amazon 4 port hub for over a year with not problems. Recently my iMac has been restarting only to get stuck on the grey screen. I did some research and found out that if I unplug it, it should restart normally, I did, and it started up fine. So is there a specific hub that I should use? Should I not use one? My iMac is a late 2012 model, running of an external SSD hard drive, because my internal drive is shot. Thanks.
iMac 21.5″, macOS 10.15
