I just got my first mac ever (24" iMac) today. First of all, I love it, and feel like I have been really missing out! When my computer goes to sleep, a light on the bottom right of the white panel goes on and off. What is this? Another thing is that in the remote thing, when I look at pictures, it starts to play some song, but then cuts out until I press a button, is this a software glitch. Should I update the computer to the newest version? Right now it is 10.4.6 Also, is there anyway to use the iSight to caputure short videos? I am sure I will be back with other questions (if anyone has a complete guide of shortcut keys I would much appreciate it!) Thanks.
