How to use unresponsive 2015 iMac as external display
I recently tried to update my 2015 iMac to the latest compatible OS. Immediately after downloading the update, it would not reboot. Genius bar says sorry, its a hardware failure (and supposedly nothing to do with the software update).
The display turns on. But apple says this model is not compatible as an external display to connect my Macbook pro. Do I really have a brick on my hands? Shame to toss a perfectly good screen. Is there any way to use it as just a screen and connect my Macbook pro or other device?
Thank you,
Armen
Ist dies eine gute Frage?
