FCP on El Capitan OSX crashes export/sharing

I've recently updated to El Capitan and since, 90 % of my exports randomly stop, making me force quit the application.
I'm exporting common 1080p with 30 frames to ProRes422 (MacbookPro 15 Retina). Never had this before.

Just a heads up for anyone thinking about updating.
I'm gonna have to completely reset the Macbook, I guess.

If someone has similar or different experience with FCP and El Capitan please let me know!
Thanks!

Could you give more information about what you're export and how you're exporting? What's the media?

Hi, thanks for the fast reply.
Since I had to continue work, I re-installed OSX, which was a bit annoying, because I could only revert to Mavericks through internet recovery, and then upgrade to Yosemite. Took a few hours.

Regarding the files I tried to exported, the .mov were shot with MoviePro on iPhone, so H264, I guess?
In FCP I simply shared to a master file, no changes to resolution or anything.

Worked perfectly with Yosemite.

I've found a few posts pop up by people having the same issue. Others report, that the application works fine, though I don't know whether they tried exporting.

Other than that, I didn't experience problems, but I didn't use deep functionality.

I'm running OS X 10.11 on a nMP and a 15" MBP, and not export issues here.

Be aware that none of the pro apps have been updated to be OS X 10.11 compatible yet, so running them on that OS is highly unstable obviously, and purely experimental.

You'll also want to report this via the Feedback Assistant app that installed with OS X 10.11.

But as for FCPX instability, I doubt there's much we can do at this point, seeing as how FCPX is not a Capitan app yet.

Thanks for the replies!

Yes, I was aware updating to the preview would be risky. I didn't have issues with Yosemite last year, so I tried.

First thing today I reinstalled OSX. Had to go back to Mavericks with Internet Recovery, then update to Yosemite.
Took a few hours.

The footage was shot with MoviePro on the iPhone, 1080p, 30 fps normal bitrate, so I guess it was H264?

Just did a few cuts and tried to share to a master file (that's how I export...) to Pro Res 422, same resolution etc.

Worked fine with Yosemite.

Interesting, that you don't have issues, BenB.
I did have a few exports go well, too.
