[QUOTE="IWT, post: 1660251, member: 83420"] OK. So you are running 10.10.x (Yosemite) on a 5 year old Mac. First critical question: do you have a Time Machine backup? Or any other form of BU? I ask because I fear your Mac's HD may be on the way out. What you could just try is: turn off your Mac if it's still hanging. Disconnect the power cable. Wait 15 minutes, reconnect the power and try to boot. This action resets the SMC. I'm not very hopeful, I admit, but it can do no harm and might just get things going. Now that we've established as much as we can about your Mac in the circumstances, more senior members of the Forum may have further suggestions. Ian [/QUOTE]
