Choosing files is freezing MAC after Sequoia Update

EDIT: It seems that at least MY issue is related to iCloud Drive!

I just recently updated to Sequoia and am having major Finder freezing issues, including any application open/save dialogs, Finder window searches, and general navigation. ANY of these actions are immediately followed by a 15-30 second delay, often while showing the Spinning Pinwheel of Death (SPOD).

Drag-and-Drop is a whole other issue, as the selected files are never released when un-clicking the mouse (which makes Force Quitting the Finder almost impossible.

Troubleshooting:

1. Rebooted (no change)
2. Repaired disk Permissions (no problems)
3. Relaunched Finder (no change)
4. Checked if Spotlight Is indexing (it's not)
5. Checked disk space (plenty)
6. Delete the Finder Preferences File (no change)
7. Rebooted in Safe Mode (It actually seemed worse!)
8. Booted into Recovery Mode and reinstalled the OS (no change)
9. Turned off System Settings > Apple Account > iCloud > Drive > Sync this Mac (PROBLEM GONE!)

I found a solution to the problem. I synchronized the Documents and Desktop folders to OneDrive using the MacDropAny app. Removing this and restoring the default folders solved the issue. Check if you have any ‘symlinks’ shortcuts.

Exact same issue, tried that all as well. In my case the issue was solved after SIGN OUT from iCloud on the MacBook (Pro M1 Sequia 15.0.1).

It was cleary an issue with iCloud Drive as it was not appearing on Finder, even tough my user was loged in and I saw the MacBook Pro on my iPhone as a device.

In my case the freezing (with all apps while choosing file to open or folder to save…) was not caused by iCloud drive. Turning off iCloud sync and even logging off from iCloud did nothing even after restarting the app and Finder and even after few reboot. As problem was still due to a cloud issue (I sync with iCloud, Onedrive, Google Drive and Dropbox) I checked them one by one. The problem suddenly disapeared when I did a clean uninstall (loging off, deleting files with AppCleaner +manually deleting folders in ~/Library/) reboot and reinstall of all Onedrive account I had previously synced on this computer. Even if Apple have to definitively patch Sequoia properly, how can it be anything else than yet another issue due Microsoft.

As iCloud and onedrive can provoke this bug I think all cloud sync app could do it and a clean fresh install of one (or more) of them might solve the problem.

You can solve it by disabling iCloud Drive.

System Settings > Apple Account > iCloud > Drive > Sync this Mac

I'm also having the same issue, and it seems it is related to the process "Open and Save Panel Service"

Still no solution though...

Open and Save Panel Service not working i… - Apple Community

Unfortunately for me, turning the iCloud sync for Mail OFF is just not an option - I use 5 different Apple devices and need my email synced to all of them.

It also doesn't freeze every time for me when I am sending attachments - it will go along happily for quite a while and then lock up out of the blue, requiring a Mail force quit - and then it's ok for a bit. Not sure if dragging the attachment from the Finder to the Mail window works any better - since I'm not seeing consistent behaviour, it's hard to test this as an option unless I do that every time.

Sooo many darn bugs with this release - I normally never update early, but did this time and now regret it. :(

And yet you were able to upload an image in your post... what you are saying that you can't do. Did you use a different OS to post your question?

Ah! I see, sorry.

Same bug, even after update to 15.0.1.

This fixed it for me as well. Just have to remember to turn it back on again when Apple fix it. I hope they mention it in the release notes...

Same here, very frustrating. Freezes during Disk First Aid run and won't open up any Adobe CC programs.
