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

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:

https://youtu.be/nrEGKD1KY0s

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

- ***

- 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: https://youtu.be/nrEGKD1KY0s? Thanks! What should i do? I just got this 2000€ laptop on Monday and I find this not really acceptable...

Someone over at macrumors figured out that after a NVRAM/PRAM reset a NVRAM key is missing which causes the stutter, see here for the solution https://forums.macrumors.com/threads/mbp-13-2018-safari-stutter-glitch-freeze-ca n-someone-please-test.2129323/ or do the following:

boot into recovery
open terminal
type: nvram 8be4df61-93ca-11d2-aa0d-00e098032b8c:epid_provisioned=%01%00%00%00
press enter
reboot

I know, seems weird but helped out quite a few people and the stutter is gone...

Apple doesn’t routinely monitor the discussions. These are mostly user to user discussions.

If you want to, you can send Apple feedback. They won't answer, but at least will know there is a problem or a suggestion for change. If enough people send feedback, it may get the problem/suggested change solved sooner.

Woke my super brand new 2018 MacBook Pro 15" v10.13 up and was looking at https://www.apple.com/macbook-pro/ noticed a very poor scrolling stutter especially over the high res pics. That link affect anyone else running 10.13? I'm assuming 10.14 will do the trick.

I have the exact same problem - the stuttering also occurs when I launch Beats 1 radio on iTunes.

Also did a full reinstall of high Sierra, cleared p-ram, and set up fresh. Still haven't found a fix.

Update: Ok it appeared that the issue randomly fixed itself in the morning. All videos are playing smoothly and Beats 1 radio is playing. This is one of the weirdest bugs I've ever seen. Mouse is no longer choppy either.

I am also having the exact same issue on my 2018 MacBook Pro 13 inch touchbar model. not sure how to fix it though and I don't want to have to reinstall Mac OS or erase my drive because of this.

Sep 3, 2018 2:33 PM in response to zymoticspade

Update 2...Now the problem is coming back as soon as I restarted or shut down the computer. Can anyone confirm that the issue is coming back when restarting?

Wow. Thank you for your reply. That is the weirdest thing I've done on a Mac, but it actually worked. Thanks!

I'm seeing the exact same problem on my 2018 13-inch MacBook Pro, configured with i7 and 16 GB RAM. The Bloomberg and IMDB pages you linked reliably trigger the “hiccup” on my MBP; I also see it on some pages under washingtonpost.com and cnet.com, among other sites.

I brought my MBP to the Apple Store, where a technician said he'd heard other reports of the same thing happening, but that there's no fix at present. Weirdly, I wasn't able to reproduce the issue on one of the display units there—though I only tried a couple pages under washingtonpost.com, which is hit or miss (on my MBP, at least).

Can anyone else confirm this is (or isn't) happening on their 2018 MBPs?

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?

I did find what is the problem for me.

I had the computer (mouse and everything) stuttering each time My MacBook Pro 15 2018 wake up after sleep.

It was because of my external display. If I turn it on, it works again, no stuterring. If the screen is turned off when I wake up my Mac, the problem comes back.

Apple, please, fix this as everything is compliant on my side.

I installed security update 2018-002 fro high sierra and it seems to fix the problem. Now 8be4df61-93ca-11d2-aa0d-00e098032b8c:epid_provisioned key appeared in NVRAM
