Q: Exporting fails/hangs in 10.2.3/El Capitan: Error: This is null
After recently upgrading to FCPX 10.2.3 and El Capitan I am having inconsistent problems exporting projects. When I go to File>Share… the export just hangs. It stays in the Background Tasks window for about 10-15 minutes, then I eventually get the "Share Failed" notification (error window screenshot attached).
Details:
- This happens with any kind of export: Master File, a preset, my own configured setting - happens to them all. Happens with exporting a full project, or just a range selection.
- Only happens after FCPX has been running for about 30 mins. When I start, I can export fine, using whatever setting. So whenever it hangs, I restart FCPX and can share the project. I just, obviously, don't want to have to restart the app every time I need to export.
- App Nap is off
- I've deleted preferences, deleted FCPX and reinstalled from the App store. I've used Digital Rebellions FCS Remover and reinstalled. I've deleted renders. None of this has helped.
- This has never happened on any previous version of FCPX or the OS. My FCPX 10.2 on Yosemite worked like a dream. I updated FCPX to 10.2.3 and to El Capitan at the same time and this started happening immediately.
Tech Specs:
- Running on a 2013 Retina MacBook Pro, 2.6 GHz, i7
- OSX 10.11.3
- 16GB RAM
- NVIDIA GeForce GT 750M 2048 MB
- External Apple Thunderbolt Display
Any thoughts or solutions would be greatly appreciated!
Thanks
