MacOS Big Sur Lagging

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.

Best

Same. I am on a new M1 MacBook Air and certain websites have terrible scrolling. I'm glad it sounds like its the OS. I was about to be very disappointed with the M1

same here! I have a mackbook pro 13inch 2017. Updated to Big Sur last week. Started noticing lags with typing esp on text message, load speed, etc.
Please help I'm a med student I need my laptop esp with things online these days.

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.

I too have suffered from this immediately after the upgrade (Macbook Pro 13 Early 2015) and restarting the computer fixed it.. phew 😅

I too have suffered this problem, also issues with the mail app, its terrible, I am using a Macbook air m1

Same issues, using MacBook Air 2017.

• Updating to the Big Sur slowed down the booting speed 2X or 3X.

• Photo Booth Camera doesn't work

• Ram consumption has peaked up and is lagging the whole system for no reason

• Even the smallest of task is lagging, which never happened in the previous Mac versions

• Can't login to FaceTime and Messages app

• Due to the lag, even typing on keyboard is lagging

The widgets might be the reason the whole system lags. (I don't want those feature then)

System - MacBooks Air 2017 (i5, 8GB RAM, 128 GB)

MacBook Pro 13 2020 16gb. Everything runs slower this is very unprofessional.

It behaves like a completely different laptop.

Same of the issues are:

• Websites have terrible scrolling.

• Unacceptable memory consumption.

Same here... Macbook pro 13 2015.

Its very laggy, even to just move the windows around

I've been experiencing the same. And experiencing stutters/lag on the 19' MacBook Pro 2.4Ghz i9 with 32GB .. So it's plaguing even the top-tier rig. I sent in a log to Apple, but basically there are stutters/lag whenever inputting text.. Like right now as I type this. And as the others have said when resizing windows.. It's not inhibiting me coding, but it's making it VERY frustrating.. especially after shelling out nearly 4k for this thing. I love the look and feel of Big Sur though so hopefully they can get this sorted out. I know developers can't snap a solution into existence, but some acknowledgement of working on the problem from Apple would be great.

Same here. MBP 2020 2GHz, quad i5, 16GB RAM. Immediately noticed the difference as soon as I upgraded to Big Sur in terms of "laggy" behaviour during general usage of the laptop. Resizing windows, typing, scrolling in safari, moving between desktops...basically everything. Was actually super content with the previous Catalina version, no gimmicks, no drama, no complaints about the OS since everything worked buttery smooth...I should've waited for the updated Big Sur version so that all these teething stages of new OS updates (especially for ones with massive overhaul such as Big Sur) get sorted out :(( For me it's definitely an OS issue (I hope, and it better be), I only bought this damn machine just over a month ago!

NOTE TO SELF: always wait for the version 2 of new tech /OS.

I am having also having this issue, particularly, with the Messages app. I get the pinwheel and/or terrible lag whenever I try to type a message in the app. This is my favorite feature and it is totally unusable! Wish everybody would just use WhatsApp now. Had the same problem with Catalina and hoped that Big Sur would correct this issue. Tried everything suggested. No joy.

Hello everyone, I also have these problems on both my Macs since Big Sur (big mistake to update as soon as it got released). A lot of graphical stuttering when changing desktops, opening apps, and minimizing windows. Slow startup and shutdown. Also, every time I manually clean-restart it, it says that the Mac restarted because of a problem. It is kinda unacceptable after many months of testing, to be honest.

Hope Apple solves this ASAP.

Excuse me for my english.

Click on the “Apple” menu and then open “System Preferences.”
Next, click on the “Energy Saver.”
Check the box near to OFF “Automatic graphics switching.”

At least for me, it has been fixed.
