Use your iMac as a display with Target Display Mode

Target Display Mode lets you use the built-in display on a supported iMac as an external display for another Mac.

iMacs you can use  as a display	Cable you need	Port you need  on your other Mac
iMac (27-inch Late 2009)	Mini DisplayPort to Mini DisplayPort	Mini DisplayPort or Thunderbolt
iMac (27-inch Mid 2010)	Mini DisplayPort to Mini DisplayPort	Mini DisplayPort or Thunderbolt
iMac (Mid 2011)	Thunderbolt	Thunderbolt
iMac (Mid 2012-Mid 2014)	Thunderbolt	Thunderbolt

Note: iMac (Retina 5K, 27-inch, Late 2014) and later iMac models can't be used as Target Display Mode displays.

Use Target Display Mode

Follow these steps to start using your iMac as a display:

1. Make sure both computers are turned on. 
2. Connect the Mini DisplayPort or Thunderbolt cable between the two computers.
3. Press Command-F2 on the keyboard of the iMac that you want to use as a display.
   

After you press Command-F2, your iMac displays the desktop from the connected Mac.

 

 

If Command-F2 doesn't work

If your iMac doesn't switch to Target Display Mode when you press Command-F2, check these things:

• Make sure the iMac you're trying to use as a display supports Target Display Mode. 
• Make sure you're pressing Command-F2 on the keyboard that's connected to the iMac you want to use as a display.
• In Keyboard System Preferences, if the checkbox is enabled for Use all F1, F2, etc. keys as standard functions keys, the key combination changes to Command-Fn-F2.
• Make sure your Mini DisplayPort or Thunderbolt cable is connected to both computers.
• If you're currently logged in on the iMac you want to use as a display, try logging out to return to the login window. Then press Command-F2 again.
• Some older Apple keyboards and third-party keyboards might not allow Command-F2 to toggle display modes. If this happens, use the keyboard that came with your iMac to toggle Target Display Mode on and off. 
• 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.

Exit Target Display Mode

To leave Target Display Mode, press Command-F2 on the iMac keyboard again. Your iMac also exits Target Display Mode if you disconnect the cable that connects the two computers, or if you shut down or sleep either computer.

If the connected Mac goes into sleep mode, the iMac screen turns off until you wake the other computer, or until you take your iMac out of Target Display Mode.
