Q: How to project Mac screen onto another Mac?

My Macs screen doesn't turn on and I'm trying to back up data before it gets fixed, so how do I project it onto another Mac screen without being able to control my Mac before its projected?

MacBook Air, OS X Yosemite (10.10.2), Mac

Connect the two Macs either via FireWire or Thunderbolt.. Note that although a mini displayport jack accepts Thunderbolt a mini displayport does not work for Target Disk mode. A mini displayport is video output only.

Boot the problem Mav in Target Disk Mode. Depress and hold the T key during bootup

Then you can access the disk in the problem Mac like any other disk.

If you previous turned on Screen Sharing then yo can use that via a regular network connection to see/use the problem Mac
