Hi Joe,
I hope all is well.
I was wondering if you can help me figure out a similar problem I’m having.
FCPX crashes as well when trying to share/export a master file, be it by clicking the Share icon to the right and clicking Master File… or going through File > Share > Master File…
I have Final Cut Pro X 10.2.1 and use a Macbook Pro (mid-2012) running on Mac OS Sierra 10.12.6.
I am unable to update any of these at the moment.
So my FCPX started crashing 100% of the time when I try to share a project, no matter what size. From reading this thread and your post, I think I know what happened. I plugged my iPad Pro 2017 (2nd generation, I believe) into my my Macbook for the first time, and iTunes asked to update software so as to be able to communicate with the iPad. I said OK, and it updated.
Ever since then, FCPX has crashed while sharing.
I read the thread and searched for the anomaly in my current System > Library > PrivateFrameworks > MobileDevice.framework file… and followed the same path in my Time Machine backup from before the issue, from March. I found that the difference is there’s a new folder called XPCServices in my current system, and in Time Machine it’s not there. Screengrab here:
So my idea was to either delete that file or drag and replace the MobileDevice.framework file from Time Machine into my current system. But it won’t let me do either. I get a prompt: “XPCServices” can’t be modified or deleted because it is required by MacOS.
Do you know what I can do to start sharing again normally?
Thanks so much, and thanks anyone else who might read this and shed a light.
Be well
Flavio
