FXPX 10.4.6 on MBP OS10.14.4. Project loads in OK, editing a 2 cam multiclip works smoothly, and then after about 10 minutes or a handful of edits, abruptly stops responding to space bar, or Cmd L or J. Nothing moves. Only workaround is quitting, and then restarting FCPX. Same scenario - works fine for while, and then stops responding.
Been using FCP since v.1.0, all through fcp 7.0 and FCPx. Been editing since early 80's on NLEs.
Edited a 2 hour show on the same exact hardware/software (with the exception of upgrading to 10.14.4, with footage from the same acquisition sources, only a month ago, with no apparent problems.
Anyone have any insights?
I am getting tired of quitting FCPx every 10-15 minutes. It's getting old pretty quickly.
Thank You.

That's a very weird problem! If you've already cleared all your render files, checked that your hard drives that the media is stored on are not deteriorating, and trashed your FCPX Preferences, I would suggest doing a re-install of FCPX.

Best of luck, let us know if/how you're able to solve this problem!

Thanks for the suggestions. I had tried everything on the list, except trash/reinstall FCPx. Just trashed & re-installed FCPx from the App store. Problem still persists.

Updated to OS 10.14.5, even though not a good idea during a project. NaDA!

I logged all the unresponsive events today: 10 no-response events in 2.5 hours. As soon as I quit/ restart FCPx, everything works like usual. Best= 29 mins, worst=8 mins before the app stops responding to play commands. I can still click around, select clips, change settings, almost anything I want to do, except get the playhead moving - in the timeline or the browser using the keyboard or menu commands. Audio files, Video/audio, or video only. No response to space bar, menu or J, K, L

I can click on the timeline to move the playhead to the clicked position, but can't make it play.

All I can think is that I installed DaVinci Resolve 16 a week ago, and started experimenting with it because of all the good reviews out there.
Perhaps Apple is jealous?

If I ever get to finish this current project, I'll be seriously considering Resolve.

Hey, I think I'm experiencing the same issue. iMac late 2015, OSX 10.14.5, FCPX 10.4.6. When it happens to you, are you unable to click/drag the playback head in the timeline and skimming stops working on the timeline – but still works in the event browser?

Just started happening recently after updating my OS and FCPX one after the other.

Trashed FCPX preferences. Haven't tried a clean re-install of FCPX or the OS yet.

There are two things worth trying. One is to reset the SMC - System Management Controller. In my experience, this can cure a multitude of strange issues including those mentioned in the support document and some that aren't, and I find it particularly useful on MacBook Pros. Secondly, there is the old favourite of resetting the PRAM - Programmable RAM. This resets various low-level system settings and is always worth a try when having issues. I would do this after the SMC reset. The only visible up-front settings that get reset are the speaker volume and the screen brightness, but there are some other important parts of the system that are cleaned-up.

You don't say which MBP you have, so in the Reset SMC document, look up the specific method for your Mac.

Reset SMC

Rest PRAM
support.apple.com/en-gb/HT204063

Hope this helps.

I have a similar problem. In my case no video file will play in FCPX, VLC, Quicktime and even Safari. Until last week the only workaround was to restart my computer.

This week i tried to unplug and plug again my external audio device (M-Audio M-Track) and the problem was solved. If i switch to internal audio card from the settings the problem also disappears. So in my case it has to do with the Mojave update along with external audio.

I have also serious bluetooth connection problems (after mojave update) as my magic mouse and keyboard tend to disconnect after waking up from sleep.

Do you have an external sound device connected?

This is a common problem. You don't need to completely quit FCP, just double-click on the project in the browser. The project/timeline reloads and all is well. This usually happens when copy/pasting transitions, I find.
