This is likely due to Apple's restrictions on their video acceleration API - most only run in the rather limited framebuffer mode. It puts a heavy load on the computer though, so you'll need a new mac mini, the older ones will have trouble running more than one at a reasonable video framerate.Īlso, no USB video adaptors that I've tested for the mac allow OpenGL or 2D acceleration. I've run into some that support multiple displays on windows, but only one on OS X. There are other similar adaptors, but you'll have to look carefully for one that supports more than one device on the Mac. It will run 720p resolution at close to 30 frames per second. It won't run 1080p30 due to USB limitations, so you need to choose a lower resolution if you need high framerates, however it does get 10-15 frames per second at 1080p resolution, so for many applications it's suitable.
Allows up to four additional displays on a mac.
