Hey guys, I know this is a basic question, but for some reason i just can't seem to figure out how to use my 24" Apple cinema display with my 13" MBP as a second screen. I obviously want to use the 24" display as my main screen (when connected to my 13" macbook) but for the life of me I can't seem to figure out how to use my MBP as a secondary iTunes, etc. screen. I typically use my macbook in "clamshell" mode with my 24" display and when I open the lid of the macbook, it's just black as if the computer was asleep but it fails to wake up when I press any buttons on the keyboard . When I unplug the mini display cable, the external monitor goes black and I'm reverted to using just my macbook. I know this can be done. Does anyone have any experience with the 24" Apple cinema display and MBP? Any help/advice/answer would be greatly appreciated and I thank you in advance!
