Sierra no wake from sleep with some video kexts [solved]

[sbuntin]

Hope this helps some folks.

MacBook (Retina, 12-inch, Early 2015), Sierra 10.12 Public Beta (16A238m)

On waking macbook, backlight would come on, but no video on display and system appeared unresponsive.

I tried removing a number of startup items, but the problem remained. Eventually I found this article, suggesting some non-apple display drivers could be a problem - https://www.reddit.com/r/apple/comments/4rrx0s/duet_display_may_prevent_macos_sierra_from_waking/

I did not have Duet Display installed, but I did have Avatron's /Library/Extensions/AVVideoCard.kext and /Library/Extensions/AVFrameBuffer.kext. These are apparently part of an iPad-as-second-display utility.

Removing them and restarting solved the problem.

Thank you so much! I've spent the whole day with this problem. Gave me a headache.

Glad it helped!

Worked for me as well. Removed AVFrameBuffer.kext and AVVideoCard.kext did the trick!

For me, it was Splashtop Streamer that caused the issue. After it was uninstalled, this issue was resolved.

This solved it mine was Air Parrot

I deleted air Parrot and both AVFrameBuffer.kext and AVVideoCard.kext and no issues so far!!

Happy I dont have to take my brand new 17 12-Macbook to the apple store.
