I have a 2014 iMac with a Bootcamp version 6.0 installed. I want to use it as a display for a MacBook Pro running windows 10 via thunderbolt to thunderbolt cable. Is that possible? or only works from OS-X to OS-X? Can someone refer me to a official documentation that states that this is supported or has done it themselves?

Nope, this is not possible. Target display mode only works if both machine are in macOS, as mentioned in the Apple KB article Use your iMac as a display with Target Display Mode.

If your iMac is currently started up in Windows, it won't enter Target Display Mode. Target Display Mode isn't supported in Boot Camp.

  • the iMac will start in OS-X, it's the MacBook Pro the one that is running windows and I want that uses the IMac as a display

  • @FrankS101 I tried that one as well myself, it also doesn't work. You needs both machines to be in macOS for it to work.

  • Did you try with a thunderbolt - thunderbolt connection or what cable did you use to connect them both?

  • @FrankS101 Yes, I used a Thunderbolt cable to join my MacBook Pro (Mid-2012) and iMac (Late 2013). It work when both are in macOS but doesn't when one of them is in Windows.
