Scrolling lag on MacBook trackpad after upgrading to macOS Tahoe

Small precision: the issue is only on Safari. No problem on Edge or Firefox.

Definitely a Tahoe issue.

Hey friends, you're not alone! Just yesterday, my MacBook started lagging with both the trackpad and keyboard, and it's been really frustrating. I tried restarting it in Safe Mode, but now even in Safe Mode, the keyboard types on its own. To work around the issue, I had to go to Apple and get a Magic Trackpad and Magic Keyboard. I think Apple needs to investigate the Tahoe update, as the problem persists even after the upgrade. Maybe we upgraded too early?

Yep I upgraded to Tahoe a few days ago and now the 2 finger scroll in every app has this super annoying delay before scrolling so it feels laggy and slow.

Do you also have Bartender on your mac?

I’m experiencing the same issue when scrolling with my finger on the top of the Magic Mouse 2 on my iMac. It seems to affect mouse scrolling only, but it creates the impression that the whole system is lagging and that something is seriously wrong. This really needs fixing, as any benefit from upgrading to Tahoe is otherwise lost.

same issue here, macbook pro M4 Max. scrolling by trackpad is jittery regardless of application. Scrolling by mouse is ok, though not as responsive as before under sequoia. Happened only after upgrading to Tahoe. Comment for trending the issue.

Definitely NOT Bartender in my case - was excited when I first read that - deinstalled pushed - rebooted - ran clean my Mac - there is nothing left of bartender on this Mac - and still the problem remains. The idea of booting in Safe Mode is good - going to try that.

This creepy "cleanmymac" is what almost certainly corrupted your user account files.

Help please? I'm having a similar problem after upgrading Lightroom Classic from v14 to 15 and upgrading to Tahoe. Scrolling in Lightroom Classic quickly becomes very laggy and even takes the app over for 10-20 seconds at a time. When I startup in safe mode the problem goes away. I disabled a few old startup/login items, but that didn't solve the problem. Checked activity monitor, but nothing jumps out at me. I'm not super-techy and can't seem to figure this out on my own. It was suggested here to run Etrecheck and post the report. I'm doing that in hopes of some help. Thanks!

Here's a link to download the Etrecheck report

I've also copied and pasted it in the "extra text." Thanks again!

Guilty as charged! I was lazy the last couple of times and migrated rather than manually setting everything up fresh. I'll delete these old kernel extensions and re-check my login items, and see if it helps. I'm grateful you took the time to look at the file, and your advice is really appreciated.

Hello all - well - my problem is finally fixed - and I was so excited that I wrote about it here. Bottom line - I used ChatGPT who bottomed it out in around 10 minutes. In the post I also included the terminal commands - because yes - it was that deep that finally fixed me.

Unconvinced that what I had is related to anything else reported here - but since I had been posting, asking for help - and getting help - thank you - it seemed right to offer a solution which might not work for you - but also an approach - that might.
