macOS Tahoe 26.0 - Bug fixes, changes, and more

[Sptzz]

Anecdotally, I'm experiencing a lot of framerate issues, especially with Mission Control. And that's on an M4 Pro MacBook. It seems to stutter whenever you return to a window after opening Mission Control. This is the sort of thing that drives me crazy, does anyone know if Apple typically fixes stuff like this?

No. I've complained about framerate issues since I bought my m3 max on launch. (last time I owned an apple product was in Snow Leopard days) I just simply got gaslight by apple stans that "everything is buttery smooth and perfect" on their end.

Also, just downloaded capcut as I needed to do a quick edit and wtf are these disgusting black lines

^^^^Yep, I have a disappearing dock also. It appeared in early betas, I believe, and is still present. I have screen saver enabled in the menu bar, and when it disappears, I click there and move the mouse, and Voilà, the dock returns.

Mine happens when waking from a screensaver. When yours disappears, do you have to then right-click on the dock to turn hiding off, or does it remain visible without you doing anything else.

What does that mean - enabled in the menu bar?

The official release (clean install) still has the following bugs:

• Add recovery contact: System Settings insists although there is a recovery contact but will not allow adding another one "at this time"
• Wake up from screen saver requires two or three repeated mouse or keyboard clicks. The first click wakes the screen up only momentarily and then the screen saver appears again
• Dock auto-hide will still turn itself on after a couple of screen saver / sleep / wake cycles, sometimes even after the first sleep
• Apple Mail: Message list font size cannot be changed from default 11 pt.

I enable screen saver, move the mouse, and the dock returns.

WHY cant I move apps around if I'm not focused on them? If mail is running behind firefox, I cant grab and move mail unless I click it from the menu bar? I cant be the only one with this issue, going to keep reading through the forum to see what people have said

So randomly my dock did not show after I woke my mini. I thought I'd inadvertently hidden it, but moving the mouse to the edge did not show the dock. I had to go into Settings, enable "auto hide and show the dock", then disable it, to make it show again.

OS 26 is absolutely the buggiest Mac OS I've dealt with in decades. The problems I've been experiencing on my MacBook Pro M1 Max this week include:
1. Slow startup every time; watching the progress bar sloooowly inch its way across now on every startup;
2. Spinning beach balls galore on multiple apps sometimes requiring a force quit;
3. Freezing up of Doc magnification;
4. Apps slow to startup in general across the board.
I had none of this before this latest OS update.

I experienced this too, especially with points 1 and 2. Disabling FileVault (which had mysteriously turned itself on when installing tahoe) resolved most of the sluggish performance issues.

Bug (tested on one machine only at this time, but it is a virtually brand-new M4 MacBook Air): Fast User Switching is super, super jank. I have to attempt switching multiple times. Sometimes I am unable to even attempt to switch without a restart. Sometimes it will switch and then immediately return to the login screen (not logout, just flip back to the login screen.) I have not done any troubleshooting at this time but would be interested to hear if others have had this bug?

 

[BotchQue]

A minor readability issue; I don't like the "shine-thru" on Mail's menu bar, where the body of the email can be seen through the menu bar items:

I did go to Settings > Menu Bar > Show Menu Bar background, clicked it on, and it did restore the solid background on the Desktop itself, so that's good, but I couldn't find a similar toggle in Mail's "Settings..." page. I also noticed this "shine-through" in Safari too, although it's much more subtle and I can live with it.

EDIT: Just remembered reading about this other toggle, go to Settings > Accessibility > Display > Reduce Transparency, that fixed me right up! I'll leave this post up just in case it helps someone else.

Let us know if it keeps happening.

nobody else having this issue? In this quick clip, I have firefox open on the right and chrome on the left. FF is the one I was on last, so I can click on links etc, but when I mouse over to chrome, my mouse cant click on anything until I click chrome from the menu at the bottom. I feel like Im going crazy Ive never had this happen on my mac before.

You're absolutely right. I just looked and FileVault was on where I've never ever had it on. Turning it off did resolve the sluggishness issue. Thanks a bunch!

Another problem with this update has surfaced: My music notation program, Sibelius, can no longer find most of the fonts it requires and deleting all of the fonts from the Library and User Library and reinstalling the program does nothing to fix the issue. It was working totally fine before the Tahoe update. It's now useless and Sibelius' tech support hasn't been able to come up with a solution. Thanks Apple.🤬

I was excited when I saw "Large clock" but apparently Settings is tripping. (I looked under accessibility options. Not there.) I liked the large clock I saw in iOS (though maybe they took that away in the release?) Was there a large clock option for the lock screen in the betas?

 

[Sowelu]

There are some bits throughout Tahoe that I cannot believe made it to release. What the hell is this. The alignment, spacing, cramped looking text. Just a mess to my eyes.

That's a weird bug I dont have that one

Bug in Safari on macOS Tahoe 26.0 (25A354):
every time I clear history in Safari then a crash report is generated.
Console --> Crash Report --> Safari

If other people can provide feedback on this bug.

Do you mean the app does not activate and move to the front when clicking on the window? Otherwise, holding down CMD lets you drag a window in the background without activating it.

 

[thebart]

I was writing a longish feedback and feedback assistant froze and I had to force quit it, losing my feedback. It was not saved in draft.

Lesson: don't write in feedback. Use a real editor that saves your work automatically.

Tahoe really sucks - a jerky, fan spinning mess on my M4 MacBook Pro. Rolled back to Sequoia today and it's like heaven. I think I'll skip Tahoe completely if I can.

 

[cw75]

I also rolled back to Sequoia yesterday and all of the problems I posted about earlier have vanished. Everything is now working perfectly again including my music notation program, Sibelius.

 

[A.F]

my music notation program, Sibelius.

Many, many people thank you for that, myself among them
So again, thank you very much for Sibelius!

(saw your post and logged in just to say thanks)

Upper left corner on Safari and in Preview. Looks odd, no?

Not noticing major performance differences between Sequoia & Tahoe when keeping Chrome tabs to a reasonable limit, even driving two Dell 4K monitors provides acceptable results. Swapping between desktops in Mission Control works as expected, even with video playback.

Have encountered a new bug (bugs?) where interface elements *exist* but are not drawn on the screen. Seems to be made worse when coming out of sleep w/ Stage Manager enabled. Running apps minimized within Stage Manager will sometimes "stick," where they become interact-able but remain squashing within Stage Manager, or expand out with bizarre resolution issues.

Also seen Dock and menubar elements refuse to render (but are clickable, if your aim is good).

From Terminal: sudo killall -HUP WindowServer
CAUTION: This will nuke the UI process, close running apps and return you to the login screen. Better than hard reboot. Might experiment with creating a shortcut if the UI draw issues persist.

Might be a wrong place to ask, but can you guys use Battery widget on Mac to show you battery levels on your iPhone and Watch? I never could, it only shows Mac battery with 3 remaining lots blank.
