I'm seeing a crash when I go to System Settings -- Apple Account -- iCloud -- Hide My Email.

This really is probably THEEEEE WORST "point.2" update I'e used that I can ever remember. At this point in the game, we should all be comfortable with the OS and seeing some optimizations and improvements. I've only seen more and more regressions over time. Some people wait until the .2 release of OS X and macOS to do their upgrade, too! If folks aren't fully up to speed in the tech world, and just normally do their upgrade from macOS 15 to 26.2 and they see all of the issues that have been posted? Ugh..

More than 1000% CPU usage with full blowing fans on an M4 Pro 14 core Mac mini, while just browsing a folder in the user Library.

Finder is going crazy sometimes even if I don't use it at all.

Or some normally never seen processes are suddenly on top of Activity Monitor and making the fan noisy while everything even the Finder is closed and the display is sleeping and I am just listening to an offline audiobook while trying to sleep.

Things like that also happen almost every day. CPU cores get overloaded with strange processes and force quitting them sseveral times is bringing them back. I have to log out for the fan being quiet again.

Also WindowServer is often using more and more CPU while doing "nothing" together with kernel_task. A force quit fixes it, but is bringing me to the Lock Screen.

GPU usage is jumping permanently from 0 to 20-30% every second no matter what I do. Even if no app is running.

And there are so much more strange things happening or not working correctly.

And on top all those design flaws...


26.2 is really the worst version ever, since I started with 10.7.x, including all betas I tested.


If they release this without a second RC next week what fixes almost everything before the final release, I am done with Tahoe and go back to Sequoia.


I'm surprised Apple hasn't fixed the issue where apps are staying in the dock after you close them. This must be one of those intentional designs that we don't know we need yet.

I also had the problem with apps not disappearing from the Dock when closed or being even double in there if they had been already been in the Dock before opening. Has nothing to do with suggested or recent apps, that's turned off. @slomtbr

I haven't seen it for while now, already in the beta before. I think I deleted the apps that caused it. I can't remember if even a "killall Dock" fixed it or if I always had to log out.

I'm seeing a crash when I go to System Settings -- Apple Account -- iCloud -- Hide My Email.

I experienced this error too after the update, every time. But a simple reboot or logout seemed to fix it.

I noticed that there seems to be 3 extremely small files that are trying to sync and are just not. I’ve tried the killall bird command in Terminal and I’ve rebooted. Something is holding it up. Does anyone know how I can find out what these 3 files are? Is there a Terminal command or something in Console I can look for?

I think the other Issues I'm having (Photos app not fully restoring & Safari bookmarks and stuff not syncing) could be related to whatever these 3 "items" may be that are stuck. Could be holding everything else up.

Yesterday I saved a file on my iPhone in the Files app to my Desktop Folder. It almost immediately showed up on both my M1 MBP (having this Problem) and on my 2018 Intel Mac mini. I moved the file to a Documents folder (also iCloud) on my M1 MBP, and it did NOT sync across to the other devices. I moved it back and then moved it to the same folder but on my Mac mini, and it synced across all devices normally, including the MBP! It seems like it's accepting, or downloading changes, but is not uploading any changes made to the other devices. This has me really worried as to what is even being backed up with Time Machine. Both Macs are sharing the same account and should have identical Documents folders. I wish there was a better way to manage this stuff.

I'd like to add that at one point I was going to try signing out of iCloud on this MBP but the warning that comes up indicates the iCloud files/folders will be removed. Seeing as though there's some discrepancies between what's here and what isn't, I don't really see that as an option right now.

If it matters, I tossed FB21276231 into the Black Hole bottomless pit...
 
There's one very significant improvement after jumping to RC this time. 26.1 had often BackgroundShortcutRunner pegged to 100% CPU and duetexpertd did often the same thing. duetexpertd is related to iCloud and some issues related to it were actually known somewhere in developer forums related to 26.1.
All this is gone now.

P. S. It starts to look like if system is sluggish and misbehaves after the update then first and simplest trick is to reboot to safe mode (and then back to normal mode) after update is done.

maybe try

or

Code:
/usr/bin/log show --last 1d --predicate 'subsystem == "com.apple.clouddocs"'

1d being 1 day of course, adjust as required

I've had this problem too on Sequoia and probably before. I'm not really sure how to force iCloud to overcome that though. Maybe adding more, larger files for it to upload? In my case it has always resolved itself, at some point, but I don't know how or if it was anything I did.

Hmmm I'm seeing a lot of these--

I've also tried Cirrus to see some more details on this, and I'm seeing some folders that should be syncing that haven't synced in Years! I opened a case with Apple, but they're not very helpful with actual problems..

 
The Mail app has now stopped updating for me. I've restarted and tried quitting the Mail app.. I'm not having any issues on my iPhone, iPad, or Intel Mac mini still on macOS 15

Submitted feedback. Can others verify this issue?

Columns cannot be resized in Finder if scroll bars visible - the handles are covering the only point of control.

Weird. A lot of users have reported it here.
I've noticed if an app is on a different partition than the OS this can happen. Likewise, sometimes apps in the dock that are on a different partition simply won't launch -- you have to delete the app in the dock and then re-add it. If the app in question is on the same partition it seems to work as expected.

For me, the only way to get Mail to start working again and be up to date is if I quit the app completely and then reopen it.. Then at some point not too long after (hours maybe?), it'll stop updating again.

Honestly, macOS 26.1 was just fine for me. Wasn't having any major issues other than some corruption in my Photos App Library file. Now that I've been on the 26.2 betas and now the RC, this is probably the worst macOS update I can think of in recent memory, going back to the Snow Leopard beta days when the -POOF- all your data was just now magically gone bug was happening.
 
If those tiny squares were the only points of control of the columns size, it would be really horrible. Luckily you can resize the columns by grabbing them at any point.
I cannot with a third party mouse and scroll bars visible all the time. I'm not finding any Finder settings or View Options that are limiting my resizing.

Edit: Double checked, when pulling my mouse the scroll bars disappear and I can resize anywhere. As soon as I plug in and the scroll bars are always visible I must resize with the impossible to grab handle. The ONLY time I can resize is if I navigate to the start of the path, click into an empty space to deselect, and then the horizontal scroll bar disappears and I can interact with the handle.

This has been happening to me at random too. I'll notice downloads and uploads and cannot find which files are attempting to sync. I've seen it as high as 10GB of data in motion constantly.


I previously submitted a BR for the iCloud Drive sync indicator turning on when OTHER FileProvider apps were syncing - Box, Google Drive, Dropbox, etc.

Sorry, I really don't understand what you want to resize. The columns' widths can be resized by dragging their vertical dividers at any point, not just at their feet. Plus, my Finder doesn't even show those little squares with those two bars (||) that you point at in your picture.

EDIT: Also, my Finder has much thinner columns dividers. It doesn't look like yours.

In settings, under Appearance, change "scroll bar behavior" to only show scroll bars when scrolling. If it is set it to "automatic" then it behaves as you described, showing them when a non-touchpad pointing device is connected. (I'm assuming that you'd normally scroll using the scroll wheel and not by grabbing the scroll bar in the UI, so it would not be a disruption to hide the scroll bars?)

Oh I see why I don't see those handles. I've set the scrollbars visible only when scrolling (which makes it possible to resize the columns by dragging every point of the vertical dividers).

Still, in 26.1 at least, those handles appear above the scrollbar if I enable them permanently.

Thanks for confirming 26.1 behavior. My bug is in 26.2 RC.
 
This "scrollbar handle" problem seems to be present only when "Show scroll bars" setting in System Settings/Appearance is set to Automatically or Always. If it is set to When scrolling, then columns can be dragged around freely from any position on the column.
