Thank you James!!

Your solution worked for my MacBook Pro, too.

Final Cut Pro seemed to work as expected until I attempted to use the menu bar at the top of the screen. Clicking on File, Edit, Trim or any of these selections caused Final Cut to immediately lock up and after a couple of seconds the entire OS would crash and I'd see a message in many languages stating to press any key for the system to reboot. I rebooted many times, reinstalled FCPX, cleared the preferences, etc. and none of that worked. I would constantly experience FCPX and Mac OS lock up and crash. It was horrible. I was grateful that I didn't have any clients waiting for their videos. Trying to resolve this issue ate up a good part of my Sunday. I probably have a few more grey hairs, too.

Unchecking the transparency check box fix seems to have worked. I can now click on those menu items and I see the drop-down menu open instead of the entire computer locking up.

Thank you very much for the tip. I never would have dreamed that the issue was with Accessibility. I never go into those settings.

Let's hope Apple fixes this bad error. I thought like many others and began to wonder if my expensive laptop was dying on me.

Thanks again.

Any chance it’s because you have "Reduce transparency" enabled in System Preferences > Accessibility?

Same thing for me. I had to use Time Machine to revert back to 10.4.6. Let me know if you find a solution please.

Did you try the solution that James mentioned?

Brilliant! Problem solved, many thanks!

I will this evening when i am at the computer. Hopefully it'll work!

Looking around at this forum and on Twitter, it seems that only some systems are affected by this. To everyone here who saw it, which system configs are you using?

I've never turned those Accessibility functions on. I'm guessing everyone who has that on has the problem.

Unchecking "Reduced transparency" has fixed the issue for me!

James you are a genius the "reduced transparency" being on was the problem. Thank you so much.

Thank you James. This worked for me! Phew!!

Spot on James. Thank you!

Thank you! "Reduce transparency" was enabled! It made fcpx impossible to use.
