I have been able to run Isadora on a Mac Studio (M1Max). I am still trying out a number of Isadora scenarios on the machine. I have been impressed by the ability of the machine to support multiple video outputs natively, for me - this is the primary reason for choosing the Mac Studio. I have tested the multi video output options with (so far) up to 6 projectors + control monitor, and with two simultaneous Matrox TrippleHead2Go devices. The machine has remained quiet and it has operated beautifully.
When using the Mac Studio I did notice a limited selection of video resolutions were supported compared to the AMD GPU’s in previous Macs. I installed SwitchResX to see if additional resolutions could be set. However, it did not appear to have any effect on available resolutions through the M1Max chip, even though the utility appeared to define more.
The availability of USB A ports, HDMI out, Ethernet, and audio out, make it much more direct when connecting peripherals.
It has nearly as much connectivity as the legacy trash can Mac Pro but that is about the closest comparison in terms of I/O support in a Mac for some time.
I tested Isadora in Rosetta mode with the OpenNi add on. I could not notice any performance loss. Although, I experienced consistent freezes on the OpenNi video and interface node using a Kinect V2.
The machine is compact and therefore is going to offer portability - perhaps again similar to the trashcan Mac Pro.
I am curious to how the machine will perform over time. It may be prone to sucking in dust and that may effect thermal performance.
Best Wishes
