I don't know really specific details of what it is but it's a MacBook pro and only a few months old with os snow loeoard. I've been sitting here for about an hour and it's still on that screen with the apple and the swirly loading thingy which usually only lasts a few seconds. Last night I did some kind of updates from apple (not sure what they were but I don't think it was anything major) but I restarted it between then and now and it worked fine so maybe it's not that... I don't know. I also downloaded a virus check thing from the apple website last night. I ran a scan and didn't get any viruses but a few warnings and put them in the vault or whatever they call it. After I finished it it wouldn't close or even force quit so I just shut down. it took ages to shut down and I wanted to go to bed and I probably did the wrong thing but I held down the power button to hurry it up like you do on pc and it shut down (that was my last shutdown).
