I have a 2011 27" IMac running OS X 10.6.8 with a mini display port and would like to purchase a 13.3" MacBook pro with Thunderbolt and use the IMac as an external display. Can I do this with a mini display port cable and will the two screens mirror or will I be able to view separate windows on each monitor like mail on the MACBook and a browser on the IMAC? Also, I will run Windows 7 in Parallels or with boot camp on the MacBook and wonder if that will still allow me to use the IMac as an external monitor?
Actually yes, you can use your 27" iMac as a external display for you MacBook. It will only work if you are going from thunderbolt to Mini-Displayport though. Refer to this article for questions. http://reviews.cnet.com/8301-13727_7-20043524-263.html
