Is there a Mac-native equivalent of xvfb for running on a headless Mac server?
Solution 1:
I don't think a xvfb-equivalent is required (Mac OS X provides the required parts).
We use EDID emulator/dummy plugs to do this on a large fleet of Mac Minis that test desktop applications. The plugs emulate a display so the GPU and associated parts of the OS activate.
The new M1 Mac Minis don't seem to require the plugs (it just works).
