Arrangement tab disappeared
I have tried everything and my arrangement tab of the display section disappeared and I can not connect my mac air to my tv please help!
MacBook Air (13-inch, Early 2014), OS X Yosemite (10.10.4)
I also had this problem after upgrading to Yosemite 10.10.4. The solution for me was to reset the PRAM/NVRAM as per the instructions here:
Resetting NVRAM
- Shut down your Mac.
- Locate the following keys on the keyboard: Command (⌘), Option, P, and R.
- Turn on your Mac.
- Press and hold the Command-Option-P-R keys immediately after you hear the startup sound.
- Hold these keys until the computer restarts and you hear the startup sound for a second time.
- Release the keys.
