High Sierra 10.13.5 video playback issues

Hi, It is important that the recovery installs the original MacOS that was in when the machine was sold. The idea is to go trough the upgrade process to have the right code in the PRAM and the right EFI files. It is also very important that the information from the user is the least possible. If you can leave out applications that you can reinstall afterwards would be much better. Please have in mind that if you have any screen reader software or anything that has to do with downloading videos it might interfere with the macbook play back on high definition. Never do any reset (PRAM, NVRAM, SMC) as this might bring you back to the original situation.

I have not had either of those problems after the change. I have a rather large iTunes song library and it scrolled through smoothly as it ever has. I tested the Messages App and noticed a very slight stutter on occasion, if there is a picture or movie within the message itself...but certainly not something outside the norm that I have seen before.

I'm on a 2018 MacBook Pro with 8GB RAM and the base Processor. I have the $1800 Touch Bar model.

It could be something as simple as you having a web page in the background killing resources for you.

In short, you are the first I have heard having this symptom after. I suspect the issues you are having now are unrelated. Please keep us posted.

Thanks!

Thats right. NVRAM reset is what brought back the issue on my Mac and after a very messy data migration *** the problem went away, hope it stays that way.

I got exactly the issue described. All the resetting, clean install won't help. Apple support kind of clueless. With Firefox the same issue. Chrome works but I believe the quality is lower. On top most of the sites I get choppy video playback with Safari.

I am having the same problem. and now that I think about it, it happened right after I did the NVRAM reset, like how the previous comments have stated. I contacted apple, and did not resolve it. This happened to websites that are streaming tv shows and movies, for example for Netflix, I could only play the trailers but not the actual episode. Netflix, and Amazon video works fine with chrome and Opera.

Has anyone solved this problem? I love using Safari because of the 1080p videos 😟 Apple need to resolve this!

No, there isn’t a Safari problem because if you try to watch a Movie on iTunes the screen will be turn black and the mouse will be choppy. If you try to see movie trailers in iTunes the video can be watched but the mouse will be choppy too. This is a bad line in the Nvram settings and is because the latest security patch from Apple is wrong for nvram reset

Yeah xD (is hard to me to explain because I’m not a native english speaker) but the main idea is that this is produced by the nvram reset in 10.13.5 or 10.13.6 because in olders versions if you restarted the nvram all works fine

I'm running into the same issue (Netflix, iTunes etc.)... also the GPU section in the activity monitor shows some strange labels:

Will it be safe to install Download Security Update 2018-004 (Sierra) on 10.13.6 again and might it help?

I'm also having this issue, system-wide. All browsers, QT Player 10 & 7, VLC, iTunes, etc. If I roll my mouse around, it acts as if the audio or video is paused and I'm scrubbing it. 10.13.6, iMac Pro.

I have the same problem, exactly as described above. Funny thing is, I didn't have it before (somehow skipped 10.13.5 and 10.13.6 because I upgraded to the Mojave developer beta around 10.13.4). Then, I got the keyboard on my MacBook Pro 2016 replaced because of keyboard issues. The Apple Store accidentally tore one of the cables in the laptop, so they had to replace all the internals, including the SSD, so they flashed it with a fresh copy of 10.13.6. Lo and behold, that fresh copy of 10.13.6 on a laptop with brand new internals couldn't play any Netflix because of error S7363-1260-FFFFD089. All the other symptoms as described above also exist, including iTunes choppiness, etc.

Tried everything as listed above, including reinstalling Sierra, High Sierra, and Mojave, the sleep trick, Safari developer mode, etc. Absolutely nothing works. Incredibly frustrating when you consider that Apple software and hardware are supposed to "just work" together! My system feels like a Hackintosh, the software is so unpolished. Really hope they fix it soon!!

Hi All,

I have the same problem on Safari and Itunes. It started when I had to reset the NVRAM and SMC to solve external monitor issues. I'm running High Sierra 10.13.6 on a MacBook Pro 13'' 2017.

If I understand well, it's a driver issue so there is nothing to do appart waiting for Apple to fix the issue (hopefully soon)?

I'm having the exact same issue as well and it is driving me insane! (High Sierra 10.13.6)

Started after I performed a PRAM reset.

Netflix, Amazon prime and iTunes movies do not work. watching video on some websites cause the mouse to lag and skip across the screen every few seconds.

The sleep trick did fix it for a while but now it has come back randomly.

hope they fix this soon as it is outrageous that a £1000 laptop cannot play iTunes movies! *sigh*

UPDATE: This problem seems to have corrected itself after a couple of days and video playback continues to work after shut down / restart. However, I don't dare try a NVRAM reset until the next system update.

I've got all the same problems. Originally I did NVRAM reset because I had some problems with my MacBookPro 2017 headphone jack. And I still got. Sleep trick didn't help me either. Let's hope something happpens soon.

Wow, that's the best explanation of the problem I've seen yet... Wonder what they can do, if anything, to fix it! Would each machine require specific code tailored to it? It baffles me that every single model year of the MacBook Pro from 2016 is vulnerable to this in some way... What the heck has happened to Apple??
