Hi, longtime Mac user, since iiE. I am really stuck! My mini is a 2012 refurbished, running Lion. it's been great all this time, suddenly, it only goes to the apple screen. having dealt with years of macs' eccentricities, I zapped the PRAM, I booted from the recovery partition and verified and repaired - it said it's fine, no repairs needed. I unplugged everything, made sure connections were good, replugged only a keyboard and mouse. I started in safe mode - it had a loading bar below the apple, when it finished loading it froze again. by freeze I mean, I walk away and come back hours later and it's still stuck. (macs sometimes just mysteriously fix themselves so I've learned to leave them overnight.) I know how to start in both single-user and verbose mode, but I haven't found info on what to do in those modes. I would at least like to diagnose the problem! any ideas? I've added no RAM, not modified it in any way. the Mac was a gift, I won't be able to afford repairs, so I have to work this out. the local computer store that does macs *sucks* and they want $100 just to look at it. my daughter needs the computer for school! thanks for any advice you have.
