Xbox One controllers should work fine when connected wirelessly via Bluetooth.
Unfortunately, they may not work when plugged in with a cable as the Mac doesn't come with USB drivers for Xbox One and Xbox 360 controllers and therefore will not recognise them as controllers.
Some people have found the third-party drivers provided in the following link helpful, but please note that these are not created by us, they are just provided for information.
