Prior versions of MacOS have broken the target display feature which I use daily. Before I upgrade to Catalina, I want to confirm that target display is supported.
Please confirm.
TIA,
David
MacBook Pro with Touch Bar
I waited a while to upgrade to Catalina, I now find that Target display mode is not working - My 2017 iMac running v10.15 no longer displays to my mid 2011 iMac running 10.13.6. When I cmd f2 to launch the display of my 2017 to 2011 nothing happens. I have rebooted both, unplugged the thunderbolt cable (inc Adaptor - all Apple) still no luck.
Any ideas?
Yes I have this option in sound menu called iMac. But no sound
Yesterday I talked with support. They sent this problem to the Apple engineers
Sorry if I am pointing out the obvious, but did you try raising the volume using the keys in the ****iMac**** keyboard? If not, select iMac and just try that...
Yes, I tried to increase the volume. But this method does not work. Also reset SMC
Just a thought: does sound play normally from the iMac itself, eg if you play a song or in the iMac (not from the MBP)?
Yes! iMac sound works fine
Does Catalina support Target Display mode?
