FCPX crashes every time I try to export my feature film.

Question

FCPX crashes every time I try to export my feature film.

I've been days on the phone with apple (I have a new iMac), but we've not solved it. It has been suggested (through many tests via apple) that something is wrong with my external drive (where I keep the movie), which is a G-Raid, and nowhere near full and only a year old. I feel like I've tried everything. I've spent five years making this movie. I'm just exhausted right now. I've been trying to export my movie for months with no luck.

iMac 21.5″ 4K, macOS 13.6

This is a continuation of this post: Final Cut crashes while rendering feature… - Apple Community

Rosemary, the report shows multiple kernel panics, which means the entire MacOS crashed. Those can be associated with general instability that causes resource-intensive apps to crash. FCP is simply the victim here, not the cause.

Your log shows several third-party kernel extensions. Due to reliability problems, Apple has told third-party developers for several years not to use those but to transition their software to the newer, safer "system extension" method.

I don't know how the third-party kernel extensions even got on your machine unless it was part of the Migration Assistant process (which you said Apple performed).

You can run this terminal command to show if any third-party kernel extensions that are loaded on your machine:

kmutil showloaded --list-only | grep -v com.apple

Another step is boot your machine in Safe Mode and see if FCP can export your file. Safe Mode disables non-Apple kernel extensions. Procedure: Start up your Mac in safe mode - Apple Support

First, completely uninstall Chrome and the keystone daemons that go with it. Reinstall FCP. Do not run malwarebytes continuously.

Next, create a new admin user and try to run the library from there with nothing else running.

There are quiet a number of kernel panics, which is worrying as they’re often an indication of a hardware issue. If you can’t export from the new user without Chrome and can’t assemble segments using the QT player, I would suggest taking the system to an Apple Store or service technician.

It's the most recent version. I've deleted all render files and preferences several times. Sometimes I get the error 536870181, but not every time. Sometimes I get a message that a particular file has issues and I replace it. Sometimes I get no message. I've tried exporting parts of my movie, and it ends up being a mess of half-saved files and I can never pinpoint where the problem is because it's not the same problem every time. Sometimes FCP crashes, and sometimes the entire computer, which is brand new iMac, crashes. Sometimes it crashes early and other times late. Sometimes it crashes when I try to render just to see if it will export better if rendered. I went through the whole movie to remove Neat video as this just slows down everything, and for a while I thought this was the issue - but no. My media is 4K with codecs HEVC/MPEG-4 AAC. But sometimes the codecs are different...like Apple Lossless or H.264 or both. Everything I'm doing is stored on my G-RAID, which is about a year old. Tons of space.

Look through this thread

https://discussions.apple.com/thread/255430040?answerId=260100930022#260100930022

If you are able to export sections of the video you might be able to assemble them in the QuickTime Player.

An EtreCheck report would be very helpful.

Use Shift-Cmd-4 to make selections of the display for screenshots.

Thanks. I will look through that thread. Appreciate it.

I do use shift command 4.

EtreCheck looks scary. I read a review it ain't good for the computer.

Etrecheck IS safe. That one text is just spreading FUD.

The application does not modify your computer in any way.

All it does is produce a report so that others here can know enough about your setup in order to help.

Usually people who fall for this false information actually have installed other things that are damaging.

If you peruse these forums you will see many of these Etrecheck reports to see the type of information they provide.

I did safe mode and FCP crashed immediately.

I don't understand this...and don't know how to do it.

I try to export ProRes422, but I have tried any number of things, including H.264, and/or not doing video/audio and just doing "computer."

I've had apple on the phone for weeks. They suspect it's the drive. They are smarter than me by miles. But I weirdly think it's the project and what's in it. I think Final Cut can't handle it. I say this, but I have successfully saved the file, but not for three months.
