Final Cut X (10.3.4) crashing on external display

Under MacOS High Sierra, Final Cut X (10.3.4) crashing when starting on external display. To recreate this event, you must close your MBP/MB lid with an external display attached - either hdmi or dvi. Run with the external display as the primary, then start Final Cut x (10.3.4). The app will crash immediately after starting.

I have experienced this crashing event on my new mid 2017 MBP as well as on my mid 2012 non retina macbook pro. The only work around I could find is to start final cut x with the lid open, then once the app has loaded close the lid and allow the cpu to migrate the desktop to the external display.

I hope that apple will apply a fix for this bug in the near future.

MacBook Pro TouchBar and Touch ID, macOS High Sierra (10.13), 3.1 ghz i7, Radeon Pro 4gb

Did you read the thread on how to avoid the problem?

I have the same problem. Imovie is also crashing shortly after loading when laptop is closed and connected to a external display.

How about compressor? Trying to export via compressor and it's not working. The progress bar doesn't move and eventually the job disappears..

Have you tried using the same workaround?

Oct 16, 2017 9:57 PM in response to ItsNoProblem

Nope. But found another workaround. Add in the specific compressor custom setting in the File > Share and it exports fine.

That worked!! That is so random. Hope they fix it soon.

I have uninstalled the LG screen manager, and since then, the crash happened very infrequently.

You do know it only crashes when the laptop is closed at launch? And after it’s opened and the monitor is accessed the laptop can be closed?

Seems to be fixed with Final Cut X 10.4! So far problem is gone for me.
