Hi guys, I just bought a new mac mini to get some exposure to the world of macs and I'm having a little trouble updating to the newest software update. When I first logged in to my computer I saw a 10.8.2 update but then it disappeared. I tried looking for the update in the app store and by the check updates button and I cant find anything. Another problem I have is that my external hdd dock keeps disconnecting if I leave it idle and I have to unplug, turn it off, plug it back and then turn it on again. Its a real pain. Can anyone help me on these 2 issues?
