I have an M1 Max MBP that was running MacOS Sequoia, and everything was perfect, zero issues. I wiped my Mac and upgraded to Tahoe today, and now I am experiencing lots of jitter here and there and lag all over the place...System Settings, Passwords app, Safari, UI, ejecting apps, copy/paste issues, etc. Safari is fast, but it has already crashed a few times, and that hasn't happened to me in years. I always tell myself I'm gonna wait to upgrade MacOS/iOS/iPadOS, but I always jump the gun and do it quickly. This time I definitely regret it. This is frustrating. I'm gonna wait to upgrade my iPhone just in case.

By the way, I like the features that Tahoe brings, but I really don't like the overall design, not fan.

The lag is driving me nuts. My workflow is slower than before.

There is typing lag in Calendar. Calendar! On an M1 Pro. My ‘99 iMac running Tiger doesn’t even lag when typing in iCal.

This is the worst performing OS I’ve used since OS X Lion on my 2008 MacBook.

And for the first time since OS X 10.4 I am considering downgrading. Apple’s QC is a laughable mess.

Has anyone with M1 machine (MBP/MBA/iMac) updated to Tahoe?

My M1 iMac has been updated to Tahoe. I found that the common dialogue (pop-up) box's animation is very jittery (Framerate drops to around 30fps). Quick Preview is stuttering, not smooth at all. Besides, Adobe AI, ID performance are bad, extremely stuttering during panning and zooming objects.

Are these issues existing in high-end machines such as M2-M4, Pro/Max, etc...?

However the Magic Mouse scrolling behavior is excellent and Safari is much snappier than previous versions. The new UI is too beautiful.
Been on Tahoe since B3 on a 14” MBP M1 Max 32GB and it’s been buttery smooth and still is for me. Had a few minor quirks (looking at you, Safari) in the first few beta releases but absolutely no issues over more recent or the final release. I don’t have Adobe software so can’t test that but not experiencing any other issues or stuttering. It’s running as smooth as Sequoia if not even better.

I’m beginning to wonder if something isn’t screwed up in my install. But I don’t know how that would affect something as simple as lag in, say, Phone app resizing.

Are you seeing any processes with abnormally high CPU or memory usage in Activity Monitor? You’re not running a VPN (I recall seeing some people having performance issues with VPNs in earlier beta releases)?

My setup is pretty vanilla - I have MS Office, the Affinity suite, the Apple Pro app suite, plus a bunch of various photo and graphic third party apps. I run a Jellyfin media server as well. The last time I set up my Mac from a clean install was when I got my prior MacBook Air M1, which I then used migration assistant over to the MBP and have just done standard OS upgrades since.
 
Same issues (stuttery dialog and quick look animations) on my M4 Max Mac Studio as well. Did a clean install on an external SSD to rule out an issue with the upgrade. It's the same on a clean macOS 26 install, so definitely a general issue.

Everything else is running smoothly tho, so only a minor annoyance. What's bugging me more is the fact that Affinity Photo V1 has issues in Tahoe. It crashes immediately when using specific tools. Maybe time to upgrade to V2 now :D
 
Have a 2021 M1 Macbook Pro 16"; 32 GB RAM & 2TB SSD. Have not had really any issues updating to macOS Tahoe so far...

...but notice some UI jittering as it seems like it is the new way it opens (window bounces a little when opening or clicking, especially with Spotlight).

I will check on my MacBook Air M3 and my M4 Mac Mini Pro. I could be wrong, but maybe it is just the new way things respond (hopefully not).

I am sure it will probably improve with the next few versions.

But now that I am aware from other posts...I notice a little slowing. It almost looks like a refresh of the screen every time I click on something and a new window opens instead of click and everything is loaded. Like a website loading. That slowness is what I am experiencing now that I check a little more.

Hope that is resolve on our M1's.
 
My M1 MBA on Tahoe has been very stable, no memory or CPU overuse issues.

However, based on comments above, I will wait to 26.2 before updating 16" M1 Max, to ensure rock-solid stability for production purposes.

I am not playing these updating games anymore...

I've updated my MacBook Air M1 to Sequoia and felt like this laptop literally aged 5 years in a minute.
30 FPS? More like 15! Everything was choppy, slow, even Firefox took 10 seconds to launch. Reminded me usual performance of 2007 MacBook White, maybe acceptable for 2007 laptop with HDD but totally not what I expect from 2020 Apple computer.

Pretty sure Tahoe will totally trash this device. So I am currently on Sonoma, found it to be as good as the OS that my laptop was shipped with (Monterey)

Tahoe is faster than Ventura-Seq. and more responsive,
I did not update the last seq. (released minutes befor Tahoe) on the MacBook Air M1 but did on the Mac mini M1.
the rule of thumbs with these unified memory chips is to keep at least 40GB free as I did for both.
Monterey is the bestest OS of our M1 but has too many flaws in th latest update, 26 to be exact.

My Rant:
yes the OS Tahoe updates will improve gradually, then get worse before the next OS... Salton Sea?
since that seems to me this new  tactical shenanigans of de-improveing an OS
will generate revenue as users will but a new MBA or min, studio for not.

Quick poll, is everyone having stuttering using HDMI for monitors?
I unplugged the TV I had connected via HDMI but rarely used and it seems to be much better, at least for now!
 
Turn off Apple Intelligence and it’ll run smoothly again. I always wondered if the higher RAM configured models suffer as much.
 
I installed it on my 13" M1 MBA. This machine only gets used for internet surfing/email/YT videos in the evenings so quite light usage. The biggest thing I I've seen is how slow it is populating the icons when opening the Applications Folder. I use the Applications Folder in the Dock to open apps usually. In all previous releases when I clicked open the folder it was fully populated with the app. In Tahoe the it takes several seconds for the app images to load as it works its way down from top to bottom. Very annoying behavior. Same thing when I tried the Launchpad in Spotlight.

I haven't really noticed much else being slow but like I said this machine gets very light usage. I've run with Reduced Transparency on for years and in Tahoe it does a decent job of getting rid of most of the Liquid Glass which I hate. Overall I find it to be much less visually appealing than prior releases. I'll give a few more days but at this point am leaning to reverting back to Sequoia.

I never saw high CPU usage. Rebooted the machine and repaired the disk with Disk Utility. System seems a lot better, but only time will tell.
 
Ok soooooo.... I have to say after 48 hours it's actually smoothed out a bunch. I dont know how to quite account for that other than "indexing" but I dunno man.... It does seem better both on the Mac and the Phone so Im slightly more optimistic now...
 
My Mac Air m2 had same problem. It seems 30 FPS when I quick look my document (image, code)..
which is not happened at 15.6.1
Please Apple. Do something
 
For a moment I thought my M1 was just slowing down with age—and it kind of is—but it looks like even the M4s are having performance issues. I don’t plan on upgrading until the OLED models come out, so hopefully this gets resolved with a software update.

The only annoyance the M1 air is experiencing is
is the very slow boot up, a white line slugs to black in 10 seconds or so.
And no auto login on star up.
 
I guess many apple users easily ignore calls of planned obsolescence, or the yearly degredation in performance as long as it still does what you need to do even if its objectively there...

And for a while now the same people liked to hate intel because they're... i don't knnow why apple uses hated intel.

But for someone who was keen to it and saw it every time... you do realise that they would have to start swinging at themselves at one point right?

I was always curious on when that would happen.. i guess by next release somehow they would have obsoleted the first of these apple superchips too.. never doubted they would find a way.

---- Out of curiosity i also have an m1 ipad pro and was curious on whether i should update that to 26 given the first real ipad changes in so many years... yeah might stick with 17, its pristine.
