I've a late 2014 Mac Mini connected to three monitors, with the third monitor running through an Apple TV via AirPlay since a third screen is not supported by the Mac hardware. At the moment the third screen needs to be manually activated via AirPlay on start-up, and again after an instance that the computer sleeps and is woken. I'm wondering whether someone may be able to write a script for me so that upon start-up or waking from sleep the third screen is automatically activated. Please let me know. Thank you.
