Macbook Air 13" will not display on iMAC 27"
Cannot get my MacBook Air to display on my iMac. I'm connecting with a brand new thunderbolt cable from Apple. I have a late 2014 iMac 5K 27" and a early 2015 MacBook Air. Trying to use a thunderbolt 2 cable to connect them so i can use the iMac as a larger display for the laptop. I've run through every troubleshooting test I can find on the web. no luck. I never see the arrangement tab in the display preferences. I did check the thunderbolt ports on both machines and they do say "Device connected"
I've also tried:
restarting both machines
disconnecting and reconnecting the cable
Option F2 Detect Displays
and other recommendations i can't even remember them all.
Any ideas anyone? please help me stay sane.
