So just recently my mac mini has acted up. I restarted it one day and it to aaaaaaaggggeeees to boot up. And I mean ages. After it booted I couldn't start any programs and was basically getting the spinning wheel. After this I restarted and am now stuck on the grey screen. I've tried everything, read everything, basically researched the Sh@t out of this. Another problem I have is the hotkey shortcuts on start up are not working. The only think I can do is press menu on an apple remote to get to the recovery disk. 20 minutes later it boots into recovery, ran verify disk, all good, ran repair disk, crashed. Rebooted again into recovery mode and chose to reinstall Mavericks. Downloaded and now hanging on 0 Seconds to Finish for the past hour. In my past experiences, I would imagine this is the HD almost dead. I've made an apointment with the genius bar for Monday as it's earliest I can get in. But I don't want to get there and have them flick a switch, fix my machine and charge me $150 as it's out of warranty. I should note that I have not done anything different. Nothing new plugged in, no changes in hardware. Just one day decided to crap itself. Any insights? I'm happy to buy a new HD and put it in myself, but just want to make sure that's the actual problem and it's not something more.
