MBP 13 2018 - Safari stutter/glitch/freeze - can someone please test?

Same issue here. Mojave beta 6 and now 7... *any* video stutters. Reddit stutters, TweetBot3 triggers the stutter just by opening it.

It's a ****ing miserable experience. I can't do this apple crap anymore. Back to Windows... ffs. so bad.
 
Not sure if this is similar but I have a base 2018 15" and cannot use the Apple website. The page will load but once I click on something it beachballs and freezes. I haven't yet noticed it on other websites. I do notice stuttering with reddit and facebook though.

reset smc might help
 
Yes, yes, YES!!!! This happens on my 2016 MacBook Pro that had its logic board replaced a few weeks ago by the Apple Store. Fresh out of the store with a fresh copy of High Sierra that THEY installed, it came with these stutters on all these different websites with videos, as well as iTunes videos! Give it a try. It also just won't play Netflix at all, and shows this Netflix error: S7363-1260-FFFFD089. See this thread https://discussions.apple.com/thread/8423529. I have been on the phone with AppleCare for hours, and have submitted videos to their engineering team of the issue. Hopefully, they will figure out what the problem is and fix it. So far, it appears to be neither a hardware nor a software issue, but a firmware one. Please do let me know if you figure anything out! For a temporary fix, you can sleep the computer for a few hours without plugging it in, and upon awakening, the computer should behave normally. But a restart reintroduces the problem, which is absolutely maddening.
 
I noticed the problem after I did a NVRAM/SMC reset on a 2016 13". Also Netflix and Amazon Video won't play in Safari anymore. As well as iTunes Movies (black screen). Probably an issue with HDCP.

Maybe the machines lose some important info after a NVRAM/SMC reset, which is not being properly restored.
Is somebody willing to try a reset on working machine, to see whether the issue can be replicated? ;)

Chrome is the only answer at this point (or FireFox if you really use that browser) - Everything works properly. It would seem Chrome (Google) isn't as concerned about piracy and making trillions as they are about their customers being able to view and enjoy the entire Internet.

I will never use Safari again. Ever.
 
it's still not fixed with beta 8. I reported it multiple times. it was fixed in beta 5 and 6. now it's back. I hope they fix it with the next one. if anyone finds a solution please post it. annoying little problem.

someone over at the apple forums claims the mojave 8 beta fixes this when installed to an external hdd: https://discussions.apple.com/message/33784676#message33784676

strange issue, especially since it only seems to affect some machines..
 
Today i went to work in the morning and left my MBP unplugged with the lid closed. I just came home for lunch break, opened it and the bug is gone at the moment. It has to have something to do with the not plugging it in part because normally I do that before I leave. This thing is getting stranger and stranger. Did anyone have the same experience?
 
This happens to me too, quite randomly. Scrolling in Safari will 'stick' for just a split second if I'm not doing anything or touching the trackpad, like if I pause to read for more than a few seconds, it will stick when I go to scroll. Very weird and it doesn't happen all the time. Can't seem to pinpoint why.

Same here. Also, messages app beachballs for like minutes before actually opening. Have you tried the solution in the link suggested by xref below? Didn't work for me...

There was indeed a missing key in NVRAM. The fix can be found here - https://discussions.apple.com/thread/8427286?answerId=33791001022#33791001022 - Thank you mattrogers

in short
  1. boot into recovery
  2. open terminal
  3. type: nvram 8be4df61-93ca-11d2-aa0d-00e098032b8c:epid_provisioned=%01%00%00%00
  4. press enter
  5. reboot

Thank you so much, that worked!

I had to do an NVRAM reset on my 2018 Macbook Pro 13" because the Touch Bar display just stayed black, even after reboots. After the NVRAM reset, the Touch Bar worked again, but I had stutters in Safari and TweetBot 3 and could not play Beats 1 radio.

Setting the NVRAM key in recovery mode fixed those problems.

I just received a base model 13 inch MBP 2018 with Touch Bar. I have stutters one some websites in Safari where the mouse pointer and the entire machine won't react for a split second every few seconds. I made a video of the whole problem:




Can someone with a new 2018 MacBook Pro please test these two websites:

https://www.bloomberg.com/europe

https://www.imdb.com/title/tt7137846/ (click on the trailer preview)

On the Bloomberg website, as you can see on the video, when moving the mouse (with the trackpad) in a circle the pointer just freezes every few seconds. Even when the tab is only in background, the entire machine across all apps stutters. It is even worse on the IMDB trailer page when viewing the video.

Can someone please test if your 2018 MBP shows the same behavior on these pages. Just keep moving the mouse around and you should see the stutters (or not)?

Is my MBP defective? What I tried:

- reinstall High Sierra from internet recovery --> freezes
- use Safari Technology Preview --> freezes
- reset Safari/delete/deactivate all extensions/cache --> freezes
- clean install Mojave Beta, just after reinstall is done test with Safari (no other software etc. installed) --> freezes
- use Chrome --> NO freezes

Yesterday I installed the new supplemental update to macOS High Sierra 10.13.6 but this doesn't improve anything :(

Is my machine defective or is this some Safari bug with the new 2018 MacBook Pros? Does yours show the same behavior? Thanks! What should i do? I just got this 2000€ laptop on Monday and I find this not really acceptable...

[doublepost=1536758775][/doublepost]I can replicate this issue. You have actually helped me validate that it is Safari. On my system, it happens also when I have Facebook and/or Twitter opened. I believe it has something to do with FLASH or embedded video playing plug-ins that take up system resources or something. Any solid solutions yet?
 
So glad that I found this thread.
My MBP 13" with TB is about 2 weeks old. Wanted to watch the keynote yesterday but not change.
Lags, freezes in about 3 seconds interval.

I'm currently downloading mojave beta to test.
 
I have this issue on my late 2013 13", could the solution posted above work for that too?

Mojave Beta installed.
It’s working now. So it’s a Software bug.

Didn’t try the other test since I don’t trust it
 
Thanks, hoping that it gets solved in mojave. There were a few times it occured for me from 10.11 to 10.13 (right now) and it seems to disappear for a while and then the issue comes back randomly.

Wow, this worked. Had been struggling with this for weeks. God bless you jimtonic01 for unearthing this fix.

(I recall resetting the NVRAM when trying to mess with "the new MBPs' Autoboot on Lid Open feature". Can only conclude that's what must've set this off.)
