Question : iMac as a display
I need to connect a PC to an iMac (iMac (21.5-inch, Mid 2010) as a display, the procedure I found is the following but it does not work. The cable I'm using is thunderbolt with HDMI on the other side. What's wrong?
- Make sure that your iMac is turned on, and the other Mac is logged in to a macOS user account.
- Connect the Mini DisplayPort or Thunderbolt cable between the two computers.
- Press Command-F2 on the keyboard of the iMac that you want to use as a display.
iMac, iOS 11.0.2
