Thank god. Makes one wonder why they even thought rounded documents were a good idea; and puts to rest any arguments for them.

the betas are a place for apple to try new things, but yes, good to see when they revert to a better idea. and i don't think ppl were arguing that rounded corners were better, as much as just pointing out that 'this is how it looks right now'.

anyway, good to see progress with 26.1

It’s ok, things change and Apple decided to shake things up for us. me, i'm just using my mac, and having a great time 👍

thanks, that did make me laugh.

still (and i feel like you know this) there's a huge difference between an incorrect behavior and an opinion about how something looks

Untested Issues
  • Wi-Fi not working on M1 MBA. Broadcom BCM4378 chipset Driver: IO80211_driverkit-1525.88 with firmware from July 11, 2025. Connects to Wi-Fi and Hotspots, gets DHCP lease with correct IP/gateway/DNS, but cannot reach gateway or any network hosts. Rebooting, forgetting network, etc. do not resolve.

Any M1 MBA users here affected by this?
Edit - all's well after the update.

Sorry, I can't read the full thread at the moment to see if everything already has been mentioned. Too sick.

I found two bugs until now. The external non-Apple display on my Mac mini is set to full brightness in the slider in the menu bar and it isn't movable.

This happens either only after after logout/reboot or also when coming from the Lock Screen after the Mac was sleeping or even without sleeping. Not sure yet.

I have to click on Display Settings to see the real brightness setting and when I get back after moving it a little it's working again in the menu bar too. I installed BetterDisplay now again to see if moving the slider there will unstuck the macOS slider too.

Second bug is a suddenly huge mouse cursor I experienced twice. The first time only when I wanted to resize a window and hit the border and the second time it was just there, not sure what I did before and it stayed for a few minutes in that size and disappeared while I wrote this text.

Mac mini M4 Pro 64GB RAM.

'better display' is awesome, and works here with my macbook and external. did it resolve the 'stuck' issue for you?
 
Can someone confirm if these bugs have been fixed in 26.1:

  • Apple Mail: Message list font size cannot be changed from default 11 pt.
  • Photos: stuck at not findings people or scanning tagged photos
Thanks.
 
I have a problem with mail not showing the correct number of unread Emails. The number displayed is up in the hundredsScratch Head.gif

Apps Drawer app, which replaced Launchpad, is not working on MBA/M4. I've just started testing out the app.

Honestly I've never understood why anyone uses it. I tried it a long time ago and absolutely hated it. I have occasionally checked in on it, and still see no reason to use it.

If I can't get uBlock Origin - without paying for it through the app store - it's dead in the water. uBlock Origin is a requirement for using the internet.

And 26 was supposed to work on the M3 Ultras the last time, https://www.macrumors.com/2025/09/17/macos-tahoe-m3-ultra-mac-studio-bug/

Did they fix it?
 
In the TV app, is anyone else not able to find a search field after selected Search in the sidebar? I can find any way to search.

(I've been miserable ever since they made us put our own videos in the TV app, but that's another matter entirely.)

Safari was amazing until they screwed up / with the extensions. They killed it at that point. Now our only choice is Brave or Ungoogled Chromium, but hopefully Kagi's Orion will change this soon. Also Ladybird.
 
After having so many horrible problems with performance and weird bugs with macOS crap-show-tahoe 26.0, I will say that beta 1 is already feeling much better. Although Apple sure did generally screw the pooch on this OS version. UX is terrible now compared to what it used to be. They should at least allow us to have choices for the UI since this new appearance is just fugly.

I'm still on Sonoma, there was nothing in the next version that motivated me to bother upgrading. So I'll just stay here another year.

TV app on Mac has no back button after choosing movie or tv show. Keyboard shortcut doesn't work either. Was all good in 26.0. Only "fix" is to quit and restart the app.
Can't understand how that got screwed up.

Anyone else have this bug?

No search field either. And, as per usual, artwork for tv series box sets is a mess.
