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

Time Machine backing up was the problem. It’s related to indexing, and the new Spotlight.


My computer was useless for days until I was able to erase my Time Machine backup drive and remove it from settings.


My computer is running fine now. Hallelujah!


I suspect Tahoe was re-indexed every Time Machine backup and trying to backup normally at the same time, without a state to backup from.


Indexing will slow things down a bit until it finishes. Not too much, though. In Time Machine settings, remove any external drives.

if possible can someone share the steps to reinstall the wonderful Sequoia and what’s necessary after the install is complete? I did not realize how wonderful Sequoia was, until Tahoe. I’ve been vigilant to always upgrade. And allow time to adapt to the new system. But this just has been to difficult with the slowness, etc.

any help appreciated.

My MacBook Pro 16" 2019 had Sequoia which ran without these hitches and glitches caused by Tahoe. The system is freezing and does not even return to normal unless forced shut down is used. I would like to roll back to Sequoia. Not all computer repair shops are capable in rolling back. The nearest Genius Bar is in Greenville, SC. (not an option). Apple what is the fix? They say you can't roll back, but you can if you can find a dealer with the knowledge. I left one in Virginia. They updated my system and cleaned up some files and apps. It work well for 30 days and now the lagging and glitching has started again. I want Sequoia.

Hello,
I have all the above but I'm not an IT guy and am in my seventies. Please explain exactly how I delete all files under ~/Library/Metadata/CoreSpotlight/.
I found "Library "under Macitnosh HD but there is no sub folder "Metadata"..............

Many thanks

Roger

The tilde makes all the difference.

There are two different Library folders.

The one you need is hidden by default, and sits inside your home folder (that is what the tilde character represents

in ~/Library).


Two ways to get to the ~/Library folder if it is hidden:


1) In Finder, hold down the Option key, and from the Go menu choose Library


2) In Finder, press Command-Shift-G and type

~/Library

As of March 3, 2026, Tahoe 26.3 is still broken for my Mac Studio 1 and 4!


It takes over a minute to log into the computer. And yes, I've read all the messages and made a wide range of changes without sucess. My issue started when I upgraded from 25.x to 26.3. Software quality is dropping @ Apple, and I hope Apple takes notice.


If this continues, I think we might just switch back to Linux or *BSD.

JUST as a thought … ?


The problems in this thread seem to suggest that Spotlight’s handling of indexing seems to be at the heart of the issue.


I don’t know if anyone saw this year’s WWDC, but Spotlight’s indexing issues are something the company said — at around the 13:45 mark — they would be addressing in macOS 27 …

Paul - Fixing this in macOS 27 is lazy, especially since many users will be unable to upgrade to 27. I am leaving behind my Intel Mac soon but many others have no choice but to live with the POS that is Tahoe. I do miss the days when 'It Just Works' applied.

Oh, I agree with you, @relhen … 


Unfortunately, it’s the only positive thing I can offer …

thanks Paul Downie— "Spotlight’s indexing issues...they would be addressing in macOS 27."


that is a liberal interpretation of a single soundbite, I appreciate you optimism however.
