I just recently sold my 2008 MacBook and purchased a 2010 revision Mac mini on Craigslist. When I tested it out, everything worked great. The guy had not reinstalled OSX, so it still had all his info. So obviously the first thing I did was reinstall the OS and it's been nothing but problems. The first thing I noticed is that there is no start up chime like my MacBook had. Second right after the grey start up screen with the apple logo appears, it goes to a light blue screen and stays there. I have to start it up in safe mode. Once there, a log in screen appears. Once I'm in safe mode, everything looks the same. However there are no options for multitouch gestures for my trackpad. The OS just feels slow. I can't figure out how to get the app store to run lion. The icon is faded with a question mark and it says I need 10.7 to use the app store. I have a feeling this is purely a software issue. Anyone know what to do? Please help!
