FCPX 10.6.6 crashes always if I open an older library which worked in 10.6.5

Creating a new library works, but if I open a library, which I created in 10.6.5, it crashes after 2-4 seconds.

As I started 10.6.6. first time it updated the library.


any Idea? Can't make any progress with my project 😌

MacBook Pro 14″, macOS 13.4

It's not unique to Apple Silicon or Ventura 13.4. The 10.6.5 library I have crashes when upgrading to 10.6.6 on Ventura 13.3.1(a) on both Intel and Apple Silicon.


There is a possible workaround if you export a library XML on 10.6.5. At least in my case that will load on 10.6.6. It's probably a good standard practice to do periodic XML exports of your library and essential projects, anyway, but especially right before an upgrade.


The crash log implied it might be related to something in a multicam clip associated with a gap clip. On 10.6.5 I successively deleted projects, each time shutting down FCP and duplicating the library, then trying to upgrade it on 10.6.6. I got to one project left, and there was a multicam clip on top of a gap clip in the timeline, but there was nothing visibly wrong with it. However when I deleted that one instance of the multicam on top of the gap, it quit crashing when attempting the upgrade. I did not delete the parent multicam in the browser.


For anyone facing this problem, my first suggestion is open the library on 10.6.5 then export a library XML and try to load that in a new blank library on 10.6.6. If you don't have 10.6.5 you'll need to obtain that somewhere.


If you have Time Machine or any other type of backup you can get it from there. All you need is the Final Cut Pro.app bundle. You can name one Final Cut Pro_10_6_6.app and one Final_Cut_Pro_10_6_5.app and double-click on each one in Finder to selectively launch them.


I ran the OPT+Clip>Verify & Repair Project command, but it didn't find anything on the single remaining project where the upgrade would crash. So there was nothing visually wrong in the timeline and that check did not find anything.


However I exported that project XML, loaded it in 10.6.6, exported the project XML there and "diffed" the two XMLs using Beyond Compare (both were XML version 1.10). There were a lot of changes which seems odd since it was the same project. I will study this more tomorrow.

Hey Guys I'm still having major problems almost exactly the same as all of the above . The library in question is a very large production library container around 370 GIG with the render files still intact for one project the final cut of my film 'Metaphor; which I did manage to salvage and back up several times with the help of an FCP.app 10.6.5 which was thank goodness hiding in Time Machine.


However as I think I mentioned three weeks ago that app is getting to be quite volatile as it clearly is finding itself in the minority with all the 10.6.6 testosterone flying about. I've had two updates from apple for 10.6.6 in the App Store but still my 10.6.6 copy crashes like a sack of bricks upon completing am update and opening of my film which is of course is a 10.6.5 creation . So I'm completely stuck and running out of ideas.


It does appear to be at least in the timeline quite a bit longer than three weeks ago when it was an instantaneous crash but now it's anyones guess when it happens or what the cause is. For instance it crashed this time when I was scrolling up the inspector.


I seem to remember this was the topic of discussion for a a problem back in January and February of this year for some people when Ventura was first implemented and I remember reading comments in FCP.com which Tom W if you're reading this I think you contributed to the discussion of back then . Do you know if it was a similar thing Tom because I've tried to scroll down all of the the threads of the conversation on that particular issue and the conversation peters out frustratingly without a final outcome or fix from anyone . I just assumed a fix came from Apple and everyone dropped the worrying and carried on as normal.


If anyone is still having problems or if there has been a fix recently could you let me know as Im kinda stuck between a rock and a hard place to resolve this myself ,and it's been a month now of not being able to complete my project


many many thanks in anticipation

kind regards


Ian
