Hi I was told I could use my IMAC 27" late 2009 as a external monitor for my Mac Book Pro I just got. I bought a thunderbolt cable but it doesnt work. Is there a command I need to use on the imac to act as a external monitor ?
iMac, Mac OS X (10.7.4)
Hi, not sure a TB cable works or not...
To use an iMac (27-inch, Mid 2010) or iMac (27-inch, Late 2009) in Target Display mode with another computer as the source:
- Make sure both computers are turned on and awake.
- Connect a male-to-male Mini DisplayPort cable to the Mini DisplayPort on each computer. The 27-inch iMac will enter Target Display mode and display content from the source computer.
Note: If you are connecting two 27-inch iMacs, connect a Mini DisplayPort cable to each computer and press Command + F2 on the 27-inch iMac keyboard that you will use as an external display.- To leave Target Display mode, press Command + F2 on the keyboard of the 27-inch iMac that is in Target Display mode. To return to Target Display mode, press Command + F2 again.
