MacOS Big Sur Lagging | Apple Developer Forums

Nov ’20

That's disappointing. Big Sur gets off on the wrong foot...

Same symptoms on MBP 2017 i5 2.3GHz, 8GB LPDDR3, Iris Plus 640.

My iMac was running beautifully until Big Sur, it is now running like an arthritic snail. Takes ages to boot up, delay in everything I try to do! My partner has a Mac Mini and he has experienced no problems at all. A solution please Apple!

Same problem. All my usual apps are sludge at the moment. I play DOTA 2 as well and it's totally unplayable. Hope they can patch this soon.

Apps on iMac 2019 4K are also lagging. Not the same experience as with the previous versions of MacOS.

Still having major lag on every operation– boot, login, cursor move, spotlight search, app launch, force quit, shut down– on both of my devices (maxed out 2017 13” MacBook Pro and 2019 27” iMac).

On my MacBook Pro, it went so far as to full break my disk– sent me into a boot/login/restart loop multiple times, rendering me unable to use my laptop at all.

Zapping both with full NVRAM/PRAM and SMC resets gives me a subtle, temporary improvement, before having to do it again. Booting in recovery mode and running first aid on all my partitions helped some, but also temporary. Reinstalling OS X from boot recovery helped my MacBook Pro, gonna try on my iMac now.

This is atrocious, Apple. Jobs wouldn’t have allowed this sh*t.

When I’m typing on my 2019 iMac 5k, it takes a long time for the letters to appear on the screen after I finish typing.

I'm running a 2020 8 core i9 MBP 16'and it is bogging my machine down too. The worst is texting. It was the same issue I was having on my iPhone XS until the update a couple of days ago so I am hopeful they can solve this for Big Sur soon. I am happy with some of the new gadgetry of Big Sur but the performance lag certainly hasn't been worth the improvements

Also a side note, if anyone has learned how to turn off the notification that air pods are available please let me know. I wear mine all day for work bit don't always want them paired with my MBP and the non stop notification is driving me mental. If someone knows how to make it stop fantastic and if there isn't currently a way to do it Apple please make one

Same here.... Changing applications is very laggy. MacBook Pro 13 2020
Programs like Safari and Psd run slower.....
I didn't pay 1700 euros for this!

Edit: Many system animations are laggy too.

Wow. I just updated to Big Sur on my 2017 MacBook Air and it is very lagging. Doing almost anything. Really noticeable on videos, like YouTube. But it is lagging with simple things like typing. It’s almost like it is still in beta. Catalina ran very well on this MacBook. I was surprised to see so many people having the exact same issues.

I have a macPro Late 2012 with 12-Core Xeon, 64GB RAM, Dual AMD FirePro D700 with 6GB each, and have the same problems.

After booting up, the graphics is ok for about 30 Minutes or so. But the longer I use it, the slower and more sluggish everything gets. Any window animation, scrolling through menus, they all are extremely sluggish.

macOS 10.0.1 (final; not beta). I hope this gets fixed soon, otherwise it is a nightmare..
And yes, I have tried everything, including resetting PRAM/VRAM and SCM.

I have the same issue with my iMac 27" from 2017. It goes away after a few hours but at first it takes a lot of time to catch up which puts me behind.

Same here. SMC and VRAM reset did nothing. Scrolling in Safari is laggy half the time, animations are slow and laggy, and my battery life was more than cut in half. God, I hope they fix this stuff in an update SOON.

I'm having the same problem. I have a Macbook 2019 and the keyboard noticeably lags since I updated to Big Sur. Please address this on your next update. I write all day on my mack and the number of typos has increased ten fold. It's infuriating.

I've been encountering the the laggy keyboard input issue on my 2020 13" MacBook Pro since the latest Big Sur update. I'm using a Magic Keyboard and have just noticed that the issue isn't happening on the actual MacBook keyboard so my guess is it's a Bluetooth issue. I've just switched my wireless Magic Keyboard for a wired one and the lag issue is gone.

In fact, apple can't fix interface lags and jerking arrows, input delay, delay in drawing the interface in the new macbooks pro 16 inch from the moment of their release - it is unacceptable that the device for so much money can not peform normally - any cheap laptop does not have input delay and cursor jerking/stuttering - if you switch to discrete graphics all problems disappear - well, apple is indifferent to these problems, it has long ago turned into a money making company - since the release of this laptop, everyone I know who has the same laptop has the same problems with it - the tone of the reports is open about this problem - and still there is no fix and apple does not want to recall these broken laptops - then that it earns money and does not care.
The problem is actually in the video card intel hd graphics 630 - when you do not do anything with the interface - its frequency is 0 - and when you open a new window or print a video card does not have time to increase the frequency from 0 to 300/400 mhz - apple need not lower the frequency to 0 - but they can't do it because then the autonomy will suffer - hence the conclusion - there is a design error of a new macbook or an unoptimized ui which at the moment requires a lot of resources - there are no such problems in windows via bootcamp.
But, it's not really our problem we paid a lot of money for a properly working device.
