Hi all, panicking here!!! My 2012 Mac mini will not start, it's been running GREAT for a year nearly... I have installed a Samsung 830 SSD and vengeance RAM. It's been working flawlessly with this in since it arrived. It worked great this morning and I've just turned it on now and get the grey screen of death with apple logo and the forever spinning wheel.... Tried booting up in safe mode and recovery mode and these don't seem to be doing ANYTHING. This is a work computer (recording) so I rely on this!! I need help as to what it could be... I could take it to the Genius Bar and send it off as I have apple care but will they look at it as I have an after bought SSD? Really in a panic here and could do with some sound advice!!
