FCPX 10.3.4 - Crashing on macOS High Sierra Beta 9??

Hi there,
Just wondering if anyone using macOS High Sierra Beta is having issues with FCPX since updating to beta 9? FCPX just crashes for me when I select the library tab. Before you all start to tell me that "its a beta, there will be bugs!" I am well aware or this and am simply curios as to whether this is a known issue or a isolated occurrence. That way I can rule out the OS as the cause.

Thanks in advance!

Did you trash preferences?

I've been using fcpx 10.3.4 on beta 8 & 9 quite successfully.

Having said that, I think this has been down to the fact that I've been doing the majority of work with little or no plugins (finally thought I'd give the colour board a try).

The final version of High Sierra is out in a few weeks and I'm sure we'll see an update to FCPX shortly thereafter (maybe even before .

First release FCPX wouldn't even launch on HS developer beta. Now it does and runs fine. Many third party add-ons still won't work, some do (like Chromatic). Until public release, there's no assurances anything will work correctly that hasn't been fully tweaked for HS.

Yes, we'll see updates to all Apple pro apps and productivity apps very shortly after the HS release. It is actually timing out well to the annual Creative Summit major upgrade to FCPX we've seen the past couple of years.

Just wanted to follow up on this. So it turns out even to this day on the latest update of MacOS that the crashing issue that I'm having with FCPX is caused by having my external monitor plugged in when I load FCPX. Not sure why but if I load the app then plug in the monitor it all works with no issue. Strange bug but I worked it out a few months back and thought you would be interested.

Have a great day!
