Tips

To make external monitor works (if you use iMac17,1 SMBIOS), you should do following steps:

  1. Open /System/Library/Extensions/AppleGraphicsControl.kext/Contents/PlugIns/AppleGraphicsDevicePolicy.kext/Contents/Info.plist.

  2. Find the Borad-ID which used in your config.plist such as "Mac-B809C3757DA9BB8D" or "Mac-65CE76090165799A" or "Mac-DB15BD556843C820".

  3. Replace the attribute Config2 with none

  4. Execute commands sudo kextcache -system-prelinked-kernel and sudo kextcache -system-caches.

  5. Reboot and everything is done.
