Final Cut Pro 10.3.4 on Mac OS Sierra 10.12.6 is Unexpectedly Quitting

Thank you.

Just and FYI, I also spoke with a Sr. level engineer at Apple this afternoon and he suggested to not work on that file. Instead, we tried several fixes that didn't work and then finally I reinstalled Final Cut Pro and in doing so it also upgraded to FCP 10.4 and it is currently working. YEAH! I also updated my OS with a couple small security upgrades I've always been afraid to do. I can't get too new or I'll break my Adobe Creative Suite CS5.

Thank you again for your help. I had definitely found myself in a rabbit hole.

I'm on a Mac running Sierra 10.12.6

Tom thinks when I updated my OS last the framework file got corrupted and I'm trying to use an older version that he provided to fix the problem.

The problem is Final Cut is unexpectedly quitting when I try to make a Share > Master File for rendering a project.

My machine is rendering via Quicktime (a work around I was trying). I'll try your fix in an hour or so.

In the meanwhile, what has happened and what do you think has caused my problem? It just seems to have popped up. I don't know of anything I've done outside the norm except this monster project with tons of files and disk space. I haven't added any program add ons.

Seems like I did update my OS iTunes. My work station is a mastery of old and new OS and apps. I'm still in Adobe CS5 and trying to get that to run in Sierra was a trick. . It still has a few problems but it works. I'm afraid to do the current update it suggests. I don't know if it will break anything. Also, Not sure if I can update to High Sierra or Mojabe (could break my workstation) I do photography, graphic design, printing and video. Blending old with new is really tough.

Thank you so much.

Hopefully, your fix will work.

I'll keep you posted.

Hi Tom,

Are you still available? I've got my machine in recover mode and have done the disabling through the terminal.

I'm at the point where I'm looking at finding the framework folder and the path you provided and what I have aren't the same. I do not have an Apple folder inside my Library folder.

Can you please advise. I'll sit tight and be ready for your help. Thank You.

Could you provide the correct path to the framework folder? Tom had previously given me a path to swap out the framework file but I'm missing one of the folders.

Here is his path

Mac HD > Library > Apple> System >Library >PrivateFrameworks >MobileDevice.framework

Once inside the Library folder, I don't have an Apple folder. Could you help?

The tilde was just part of an example and not the actual search.

The path you gave me doesn't have the apple folder within the Library. That is my problem trying to access the framework. Here is the folder that opens up when I copy/paste your path. There is no Apple folder. Why?

Can you see the entire thread I've had with Tom. He was quick to respond at first but now he's not replied in a while. My machine is currently in recovery mode and I can't get work done. Not sure the fix but if you can see the previous posts with Tom everything will make sense

I'm a tech geek myself about most things. I like knowing how things work and how to fix them. Any ideas on how this might have happened?

Thank You!

Not finding Apple folder in Library. See screen capture of Macintosh HD folder open. I have the Library folder open also. You can see what I have.
