Hi guys I have acquired a 27 inch late 2011 iMac suspecting LCD problems ) , I am trying to connect it to my tv, via mini display port to hdmi cable , I am getting no signal at all on the tv. IMac boots up fine and does start up chime, the iMac currently has no hard drive in it , could this be the reason why it will not pick up signal? Does the iMac need a hdd with os loaded on in order to use the thunderbolt ports?


(Noob to Apple products )

Haven't ever tried an external on an iMac but if it is the same as my Macbook Pro, the external display doesn't come on until the OS X login screen appears.

Apparently 2011 iMacs came with Thunderbolt ports, so your iMac may be older than you think...

From what I can read, the iMac has to actually boot up and detect the display so until you can boot it I am guessing you won't get far.

Did you get it second hand in 2011?

Looking it up, apparently a Thunderbolt port is a souped up version of the Mini DisplayPort so the cable should still work no matter what. Still need to be able to boot the mac though, methinks :(
