Severe lag and freezing after macOS Tahoe update on MacBook Pro M1

The experience has been terrible for the last week. After a few hours of use, restarting becomes imperative. The mouse pointer and windows lagging behind every click and drag, sometimes appearing and disappearing randomly all over the desktop.

Please Apple, update Tahoe ASAP!

I'm running it on MacBook Pro M1 Pro 1TB (half empty) 32Gb Ram

Original Title: MacOS Tahoe becoming extremely sluggish. Anybody else too?

The finger print login doesn’t work. You have to hit power button to wakeup the system to name few more in the update saga. This update has been complete mess.

Does anyone know if it's fixed with Tahoe 26.1 ?

Had to downgrade to have a usable Laptop.

Upgraded to 26.1 and didn't notice as dramatic of a slowdown that I had on 26.0.1.

But I applied all solutions from this thread earlier.

It solves the problem temporarily, after few hours the same lagy

Having the same problem. I ran EtrePro - here's what it reports - the major issues were No system uptime found and No operating system found. Huh?!?!?!

Any ideas?
