Input is just HDMI, so works on Linux without issue. There might be an app or something that lets you control the settings, but I've never used that once. All relevant stuff can be configured from the front panel buttons. I think the Mac issue is that macos slightly dithers/moves the image with a high rate which would kill the EInk pixels quickly. There appears to be an app to deactivate this behavior though.

HDMI is not always plug and play. I unfortunately encountered a situation where a Phillips HDMI display only worked with Windows, but not Linux due to EDID/Nvidia driver issues
