I just got my iMac on Christmas and everything is perfect. But i'm trying to go on GarageBand. I click on the 'Eye' icon in the bottom left hand corner to check out some of the beats and add them to the time line. I click on the Electric and then it comes up with some beats on the right, but they're all greyed out. I clicked on one anyway, and it came up that I need to install recent updates, I clicked on 'Download Now' and a pop up come up saying "Checking For New Updates" after a few minutes it basically said there were no updates that i haven't got aka. Everythings up to date. I went back into GarageBand and tried again but then it came up with 'Updates Are Currently Being Downloaded' so i left it for 4 hours whilst i went out, went back to GarageBand and it still said the same thing. I restarted my iMac and when back to garageband and it said that i needed to install updates again...it does the same thing everytime. No one has a clue what is going on. Please help me as, GarageBand was the main reason I wanted an iMac! Any help is gratefully appreciated. Thank you.
