I've used in festival and corporate events four times, Resolume perfoming great, what I am always struggling is that you need to have with you a converter, adapter and edid manager, hdcp killer. because there could always something that doesn't work as expected especially with a led processor or a graphic mixer like barco s2 or analog way aquilon (with mac in general).
Just an example, the built in hdmi port doesn't worked as expected, blacking out from time to time, usb-c hdmi adapter worked like charm (the unit was sent to apple care but didn't find any issues).
So be prepared
ps I am a big mac fan, usually since 2002 but I always have a pc as back-up
