macOS Tahoe 26.4 - Bug Fixes, changes, and more

Click on the website and click remove. Simple.

Simple??? What you said is ridiculous and annoyingly bad advice.

We get dozens or even hundreds of cookies in our browser. Most are not from sites we visit. The only way to clean many cookies without losing logins is to open the Manage Website Data window and shift-click select all the cookies you want to delete.

This is how Apple and other browser makers have always intended it to function. It is broken in Tahoe.

Bad advice, oh really? Therefore, why don't you command-click on the ones you want to delete and click remove or is that too difficult for you as well?

Manually unmounted external drives now remount after sleep...

Previously I might have given Tahoe 5/10.

Now I’m giving it a big fat zero. 0 out of 10.

It’s not only the many bugs we have all mentioned. There’s just so much more bugs that should not exist in ANY modern operating system.

Check this one. Go to Safari’s Settings/Privacy pane. Click on Manage Website Data. Try to delete cookies manually.

Since the very first Safari release 20+ years ago it was possible to easily delete selected cookies by pressing the backspace or delete key.

Now it is a struggle. It is either unresponsive, or it takes multiple attempts, and some cookies refuse to be deleted unless I clear everything.

Absolutely stupid. Idiotic. Garbage. Nonsense. Zero out of 10. Nobody checking any quality. Probably vibe coded garbage.

Working fine here.

They've pointlessly made the sidebar wider in Mail (where you can see your mailboxes). In the past this has happened in Messages, Reminders, and Whatsapp. My screen doesn't get bigger with each upgrade, but the windows do!

New release, new bug in Music app: click any of the categories on the side bar (songs, albums, artists, etc.), browse, scroll down, and when clicking to the empty part of the sidebar, it will scroll back up to the beginning of the category.

Updated broken custom icons on Intel Macs...
On macOS 26.5 beta1, the problem hasn't been resolved yet.

EVERYTHING BROKEN... the folders increase in size when copying and pasting into the info, but the custom image isn't displayed.

Come on Apple, just one more effort, you can do it...

in Apple we Trust!!!

Is anyone having degrading WiFi issues with this release? It’s gets to the point where I’m connected to the WiFi, but Zero bandwidth.

Just bought my first MacBook Pro M5 & updated to this latest release. I love everything about it, but this issue is going to force me to return it.

The only thing that temporarily fixes it is a restart or forgetting my Wifi & reconnecting.

Check that the Wi-Fi interference is not caused by devices that are always connected (USB sticks, SSD drives or other devices on the USB C ports).

It is known that some devices or adapter cables such as USB A to USB C that are not certified or not produced by Apple, over the last few years on some MacBook models, have caused these problems... I don't think it is a problem due to the mix of MacOS 26.4 and MacBook M5.

Hope! I actually did 2 things before I left for work this morning. Took the MacBook off of the Windows laptop (which was turned off) and put in on the table in front of the Windows laptop & unplugged 10+ old USB speakers from the Macbook that had a thunderbolt adapter.

Got home & took the MacBook out of sleep mode & fired up Speedtest with best download results I’ve have attained so far. These excellent results are with the Macbook further from the router & my personal Windows & work Windows laptop stacked in front of the MacBook blocking the router, so technically more WiFi signal blockage now because the MacBook is also closed & connected to a monitor.

Will be testing regularly & if this issue does not return, then the MacBook is a keeper. Thanks for the tip.👍

Surprised we didnt get a 26.4.1 today like ios and ipados did

Adding menu bar controls from system settings is causing a catastrophic bug that freezes the entire system. I cannot quit the app and I needed to force shut down my entire computer. I’ve never had to do that on macOS!

Manually unmounted external drives now remount after sleep...

And 26.4.1 did not fix this...

Just ran 26.4.1 update and the folder icons now correctly show for Intel Macs.

Manually unmounted external drives now remount after sleep...

Noticed it as well. Very annoying (I set my CCC backup volume to unmount after finishing backup, now I have to remember to eject it manually every time I undock my MBP). Is there a terminal command trick to revert to previous behavior?

Same use case here. It is a nuisance indeed.

I found a workaround that prevents the (backup) drives from mounting at startup and after screen lock / sleep.

In Terminal, I added a line for each backup drive in /etc/fstab with: EDITOR=nano sudo vifs

Lines should be in the form:

UUID={Volume UUID} none {TYPE} rw,noauto

You can locate the {Volume UUID} and {TYPE} by diskutil info "drive name" (type for my drives is apfs).

For anyone reading this - modern macOS does not create /etc/fstab by default, but you can create it yourself, and then it will use it. But it's still not optimal, because it'll prevent the disk from mounting automatically when connected. The previous behavior was ideal - it mounted automatically when I connected my Mac to the dock for the first time of the day, automatically started CCC which then unmounted the drive after finishing, and then it stayed unmounted until the next time the Mac was connected to the dock (usually the next day). Perfect for daily backups without any user activity. Now, it's either manual unmounting after each sleep, or manual mounting on first connection (with the noauto parameter in fstab).
[EDIT]: this can be solved with a shortcut (to run a shell command mounting the disk if in the home network) and automation (to run the shortcut when connected to power).

Update: this issue is solved in latest macOS Tahoe public Beta 26.5...
