High Sierra 10.13.5 video playback issues

Would you please keep us updated on how the engineers resolve the issue for you, Moodle? I'd be extremely curious as to how they handle the case for a super-new MacBook.

Congratulations, I have had more than 2 weeks without the fault. I strongly suggest you do no reset PRAM for any reason.

Thank you! That worked brilliantly.

You're welcome. I'm happy to help.

THANK YOUUU 😍

I did exactly what you proposed and it worked brilliantly well !!

MacBookPro14,1 (MBP 13" 2017, 2 TB Ports)

Hi Matt,

I'm always cautious using terminal. So please could you tell us where you got this from so we all know what we are doing?

thanks.

I would no be so sure about the permanent fix but seems that it is a good work around.

Solved! I tried Matt's method a second time and it worked. Likely I entered something wrong the first time.

Many thanks, Matt, and everyone who's helped me!

I really hoped that would be the case. You're welcome.

I have the same issue.

Also during some live streams:

The media playback was aborted due to a corruption problem or because the media used features your browser did not support.

Chrome and firefox ok.

I tested Sierra, High Sierra ***

Same problem. Also choppy video Itunes.

Finally concluded that security update 2018-003 causes this, updating new video drivers.

Video driver settings are flashed in a chip. So rollback, clean install does not resolve.

Nothing to do with EFI file settings.

All working now.

Succes.

And now a clean install running 2018-004 update. Nada.

Beta 2018-004 worked.

But after vnram reset issue comes back.

Installing official release 2018-004 does not resolve.

Reinstall 2018-004 after Sierra clean install. NO nothing.

It is possible that a "latest" firmware folder/file is missing in the EFI partition.

Forcing reinstal 2018-004 does not rewrite settings is the chip.

So i think we have to wait for the 2018-005 release.

If installing 2018-005 resolves it great but do NOT use nvram reset afterwards.

Hmm developers, please fix it.

Hmm yeah they force you to update haha.

Already tested the issue and is the same for Sierra, H Sierra.

2 sec video and 1/10 sec system freeze for streaming video and Itunes video.

A few streams report:

The media playback was aborted due to a corruption problem or because the media used features your browser did not support. (earlier post).

Test Itunes video running Trailer.

Ok everyone,

Lets recap.

Nothing to with Safari. Also problem with version 12.01

Nothing to do with extensions.

Nothing to do with Netflix help solutions.

Nothing to do with version Sierra, H Sierra and Mojave.

What is going on!!!

Security update 2018-003 writes new video drivers in the nvram chip.

With an error.

So reinstalling, restore and so on all versions does not resolve.

2018-004 update did resolve my situation but caused a subtle true color change, so i did nvram reset.

By the way, the subtle true color change is also visible using W10 bootcamp and color lcd from mac.

The color lcd icc is always downloaded from chip during clean install macOS.

The nvram reset resets all to default settings but NOT the new video driver settings.

Some temp sleep etc using H Sierra and Mojave is fine.

I talked to Apple 30 min. about this.

They have to make new video drivers, eventually a new firmware.

So hopefully solved releasing 2018-005

The issue is since jun 07 2018 when 2018-003 was released with video driver update faults.

Why is Apple unable to resolve the problem?

Not good isn't?

Hurry up please.

No solution? What do you think? Difficult isn't.
