MacOS 26 seems slow. Scrolling, typing, etc all feels delayed, is this an issue with the OS or is it something else? What are probable causes of this?
Got a tip for us?

That is not uncommon for Beta 1 Developer release. Developer 1 beta is not really meant for day to day general user use.
Sure, I have delays/slowness but, I realize it's first beta. Probably the slowest/least responsive beta of Mac OS 26 we'll have. Each update will probably get better and better. Especially the final release candidate.
I did a restart of my computer, seems like that fixed the issue.
Safari doesn't load pages after a good while of browsing in this beta for me. I end up starting up in Safe Mode to get it back to normal. They will fix this.
are you running any extensions? safari is not doing that here....
I have noticed this as well. There is a dramatic difference when restarting the app in question. Something is building up and not being cleared properly. Fingers crossed it will be resolved in the next beta.
The probable cause of it is that you're running an early version of a beta OS that was released to developers for testing.
My internet was also slow, but thats also another issue entirely.
i Do especially with the email app , the Calendar app and the text app : i take 5 minutes before they open
The graphics being used are heavy for old gpu's. Its a way for Apple to make old machines obsolete and drive upgrades.
I haven't noticed any real slowdowns or glitches with my MBP, despite running a lot of development and graphic design apps on this machine.
For anyone with slow opening apps, did you upgrade from MacOS 15 to 26 or just install 26 fresh without any backups imported?
If you imported a backup, it could include corrupted caches or similar old junk that could cause you problems. You can look at clearing those for a potential fix. I don't know about running them on MacOS 26, but they work on MacOS 15 so your mileage may vary.

Sadly, that went straight over their head.
The user with an amazing experience using MacOS Tahoe 26 beta reset their machine before upgrade. Over in another forum, a user was complaining about slow opening apps that was fixed by resetting caches and forcing the OS to regenerate certain things.
Your mileage may significantly vary, but MacOS is MacOS. We needed to reset caches back in 10.X days and we need to in the 15.X days. It is very likely we'll need to in the Tahoe 26 days too

If you can’t diagnose and resolve this issue yourself, on the developer beta, then the developer beta is not for you, and the best course of action is to reset your Mac and reinstall a production version of macOS.
Betas (especially early ones) probably have a bunch of debug and unoptimised (i.e., get it working, then make it fast once it works!) code, do not expect them to be fast.
The dev betas are literally for developers to test against and develop new features against - not intended to run as your primary device for daily use. They are not representative of the final product and typically aren't even anywhere near as polished the first public beta.
It should be hard to make an M# model lag, regardless of what people are saying about it being a beta, there should be no particular reason for it to slightly lag.
notice the weasel words
also, first impressions matter, beta or not. windows vista can tell you that.

My only complain so far is battery life but it is expected. System feels as snappy as the older version and quite stable so far.
