MP 1,1-5,1 Mac Pro suddenly won't play any videos whatsoever...

[abcd-abcd]

Hello all

Sometimes my Mac Pro won't play any movies at all - on any browser, at system level, in Quicktime - and can't preview moving images. I either have to restart the Mac Pro, or suddenly the ability to play movies might return. Any ideas why this might be happening?

This may or may not be relevant: there's a million lines of this in system.log in the Console - I have tried to delete Rubbernet & Wondershare files, but it doesn't seem to have made any difference:

Thanks in advance for any help.

Hello - has anyone else experienced this? Movies not playing on your Mac? A restart seems to fix it - but why is it happening at all? Thanks

Can you play videos in Safe Mode?

Also, are your Mac Pro in vanilla state, or already OpenCore-ed?

Already

Thanks for your replies. It's really weird - I can't play videos at all - on system level, in browsers, Quicktime, anywhere... but they after a few minutes it's ok again and all videos can play. Very strange.

Same issue here on a 2018 Macbook Pro and Big Sur 11.2 (issue was also there at least on 11.1)
Suddenly all video (and audio) are not playable in any app, no quickview, no video in browser.

And for me so far this problem was persistent till the next reboot. I didn't just go away.

mine are playing in super duper fast speed - start to end under 1 second

It seems in my case the issue is related to a USB microphone/speaker. So once the video stopped working, I was able to get it to run by switching the sound output to the internal speakers. If I switch back to the USB speaker the video stopped.
Unplugging and replugging the USB speaker resolves the issue.
Its a better workaround for me than having to restart the whole macbook.

The solution: it's my Focusrite Scarlett 2i2 mk1 audio interface causing the trouble - when it isn't working properly, movies won't play. Whenever my Mac Pro sleeps & re-wakes, the 2i2 doesn't wake up. So, before sleeping the Mac Pro I have to disconnect the 2i2, then re-connect it when the Mac Pro is awake again. Unfortunately the 2i2 rarely wakes up even then, so I have to keep plug/unplugging it (20 times? 30 sometimes) until it wakes up. It drives me nuts. But that is the solution.

You are not the first person I've heard reporting an issue with older audio interfaces acting up or causing issues with latest OS updates. All seem to be "hacked" installs of some kind. Unsure if there's something in the hack/patch that causes.

What exact OS version are you using right now? (Build number)

Thanks for your reply. Is this what you mean? System Version: macOS 10.15.7 (19H2)

.. though it has been a problem with all versions of the OS..

 

[bsbeamer]

Yes - 19H524 is the latest build of 10.15.7
If you have a spare drive, may be worth fresh installing macOS without hack/patch to see if it resolves at all.

Thanks #bsbeamer - good idea, though it's taken me a long time to get this Mac working properly so I'm not going to risk changing anything with the OS at the moment!!
