Just got the CAC-1510-A to connect a M1 iMac with the 30” cinema display. Unfortunately I haven’t been able to get the proper 2560×1600 resolution, even while holding down the option key prior to choosing a resolution.
What am I missing here? I’ve heard of people that have had success with this adapter and a M1 Mac mini, so perhaps it’s related to the iMac specifically?
Any help would be much appreciated!
