MacOS Big Sur Lagging | Apple Developer Forums

Hello! Help please, after updating the system to Big Sur, my MacBook Pro 13 began to slow down, previously there were no such problems.

I'm glad it's not just me. Was beginning to think there was something wrong with my Mac. I bought the i9 iMac and really spec'd it out; built to order. But on Big Sur I get stutter animations. If I slowly move my mouse around the cursor is jittery. Almost like it's a bluetooth error but I know it's not. Watching videos and some of them will stutter too. Scrolling stutters. I have to shutdown my computer and restart to clear it up.

And my Apple Wireless Keyboard is not wireless anymore. I have it plugged directly in with a lightning cable because trying to type on it wirelessly would lag and mess up.

This is pretty ridiculous. I hope macOS 12 fixes this.

The 11.5.1 update caused video/trackpad stuttering. I also lost my directly-connected Dell monitor (iMac thunderbolt to Dell DisplayPort) video. Turning off the Dell fixed the stuttering. Moving the thunderbolt connection from the iMac to my CalDigit hub fixed the second monitor issue. Is it possible to update or reset the iMac's thunderbolt port? I've reset the PRAM so far...

yes, the interface ceases to slow down when switching graphics - well, the question is why should I pay for the laziness of the developers with the laptop autonomy by using radeon videocard

Going to battery under system preferences and unchecking Automatic Graphics Switching fixed this for me.

Hi,
Even i cant watch videos on youtube at 720p. Forget 1080p. It is so lagging. Updating to big sur was a big mistake.

If you are experiencing video lagging try resetting your SMC:

Power off MAC and leave the plug attached
Hold down Shift + Ctrl + Option and Power On button for 10 Secs.
Release buttons and then power on mac.

This should remedy most issues with the new update Happy Crimbo.

After installing big sur, the animation started lagging when scrolling in Safari / notification center. Does anyone have a similar problem? Scrolling occurs in some jerks, and this is on a standard MacBook trackpad. When scrolling through applications or scrolling through the Launchpad, some animation problems are also noticeable . folders in the Launchpad open with some slowing down.

When restoring to Catalina there are no such problems

I found partial solution for me. You need to reduce mouse polling rate to 125-500 in mouse program. Example: Synapse 3 for Razer Mouse. But Synapse 3 dont support macOS, and i reduce this setting via Windows. (has just been installed for some work tasks). I hope its help for you guys.

The SMC reset worked for me. I was skeptical, but the video performance after doing that is now what it used to be before updating to Big Sur. I'm using Mac Air 13 inch, early 2015

This really works!
Just go System Preferences -> Batter -> And Battery in left side menu.
I already wanted to reinstall whole system...
