High Sierra 10.13.5 video playback issues

As Matt's post states, this instruction was provided to him directly from someone inside Apple. I'm sure no one here could explain in detail what does that instruction, but somehow, it works.

Sifting through the responses on this topic, I noticed that the stuttering started with a PRAM/SMC reset. Personally, my issues started right after the reset.

Yes, the stuttering stopped after entering the code.

Apple is consistently number one year-after-year in customer satisfaction amongst other tech companies but it's unreasonable to think Apple is perfect. At least they're #1 😉

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.

Typical a dumb solution.

Get new hardware. YEAH!!!

Ok do it. Do a clean install with all the updates.

YEAH do a pram reset. et voila get new hardware.

Ok don't

Apple support does NOT understand a wrong 2018-003 release.

Earlier I said that i'am going to delete all my Apple ID's.

Hmm I wait a bit but not much longer.

The High-Bandwidth Digital Content Protection is a possibility.

Thanks Astelin55.

Also I talked to support about the issue for a long time a few day's ago.

I said: read this forum part.

No we listen only to individuals.

Also said "video runs for 2 sec and 1/10 sec freeze".

They don't trust me and asked to capture video of this.

The F word idiots!

Incompetent.

At the end of this week its over and done.

No Apple for me anymore.

Selling 2 MBP and 2 iPhones.

YEAH $6000,

And will buy Samsung and other hardware.

So.

Hi Matt Rogers,

It works!

You did it just before my deadline deleting Apple ID'S.

Yes i was angry.

Now knowing Apple is investigating ,i called them again about nvram settings, i will keep my Apple ID and do not sell my MBP etc.

How do you know: nvram 8be4df61-93ca-11d2-aa0d-00e098032b8c:epid_provisioned=%01%00%00%00

?

What do you know about nvram settings and writing what commands?

Interesting.

Thank you very much!

Also thanking everyone doing and thinking about this issue.

This morning I passed by an Apple store and checked up the Macbooks on display and looked if these were updated to 10.13.5 and the iTunes 12.7.5.9 which are the latest public releases. The computers worked perfectly fine with any streaming on Safari. I decided to update as well from 10.13.4 but I did it in the following order.

1. Update time machine back up

2. Start in recovery mode

3. Erased HD with disk utility

4. Erased container files with terminal.How to Delete APFS Partition on macOS Sierra

5. Recovered from Internet. When the computer started it was already in 10.13.5

6. App. store asked me to update iTunes additionally

7. Machine running well with a temporary account I set up for this purpose.

8. Used migration assistant to recover my original account.

9. Issue gone.

My machine was never updated to 10.13.5 before. The machine that was updated trough the normal update procedure I did not managed to get the video working properly.

I hope it keeps working well.

Try to refresh SMC and nvram, if the issue is really gone, after the refresh the MacBook will be work fine.

For me the issue was gone for a couple of days, but when I tried to refresh the nvram and smc the issue was returned.

Thanks for you reply. I tried it and it didn't work for me 😟 Wonder why... Also, the Apple "Tier 2" rep I was talking to has stopped responding to any of my messages. Maybe they're just not willing to figure it out?
