System Information
Operating system:

System Version:	macOS 11.1 (20C69)
Kernel Version:	Darwin 20.2.0

Graphics card:

Chipset Model:	Intel Iris Graphics 540

Blender Version
2.91.0 2020-11-25 08:34
0f45cab862

Worked: (newest version of Blender that worked as expected)
2.83 worked fine, but under Catalina

Short description of error
Since updating to macOS Big Sur, saving of new files & even opening files has been extremely slow. The status bar indicates "Listing Dirs..." for several minutes before file access proceeds.
Blender also had com.apple.quarantine attribute, but removing it didn't fix the slow saving/listing.

Exact steps for others to reproduce the error
It happens with Desktop folder. Problem seems related to the OS itself.
Tried giving Full Disk Access, as well as specific folder access to Blender too.

Does this only happen with 2.91.0 or does 2.83.x have the same issues when used on Big Sur? Are similar issues happening in other applications?

Roger McCarty commented

2.83.0 same behavior. I ~have~ dropped all network connectivity so I know it isn't trying to scan attached server drives, Dropbox, etc.

Trouble became noticeable after update to Big Sur.

Blender has folder access enabled, and I have at times tested with full disk access. No difference.

No similar trouble in any other applications.

if you let run the "activity monitor" next to blender do you see a cpu spike on any process ? (make sure you see all processes)

Some suggestions:

Try removing and re-adding blender to the "Privacy" > "Files and Folders" section shown above.
Try cleaning the caches
Make sure the network you are connected to is properly set up. There are different problem that can occur related to sip, tccd, sandboxd etc.

No CPU spikes
As mentioned, have removed/added privacy multiple times, no effect. Have provided full disk access as well, no effect.
Issue occurs with or without properly configured network.
~Which~ caches? how?

After add'l investigation, I've determined that the issue is related to opening/saving files on the desktop (and probably also download) and the relatively new feature to control access to those locations.

But, I've been unable to workaround or resolve the issue by turning off the access and then re-enabling access. Also, allowing full disk access to Blender does not resolve the issue.

If desktop is synced with some cloud service, try saving to some other folder.
Also, share the output of xattr -l -r path/to/Blender.app

Issue ~is~ in fact related to desktop and it is synced with DropBox. Saving to other folders works normally.

Where was Blender downloaded from ?

official site, blender.org

Not sure why it's quarantined.. it can be removed by running xattr -d -r com.apple.quarantine path/to/Blender.app
Let us know if that gets rid of the slowdown.

xattr -d -r did not resolve issue

and yes, xattr -l -r confirms quarantine is removed. no output from xattr now.

Sorry, I misspoke. Desktop is NOT synched with Dropbox and has never been.

Removed Blender app using App Zapper, removed entire folder named ~/Library/Application Support/Blender. Rebooted.
Downloaded new copy of Blender 2.91 from org.
After install used xattr and noticed it was installed with quarantine.
Ran xattr again and noticed the quarantine was NOT removed.
System preferences show that Blender has full disk access.
No change to slow behavior when saving to Desktop.
Attempts to open files in Downloads also slow with Listing Dirs ... status.
Desktop is NOT synched to Dropbox, I misspoke, sorry.

I noticed when i was saving a tiny scene just now, about 8MB, to an external m.2 Drive, saving was also slow. About 3-5 seconds at least.
The drive can read/write at about 1GB/s, so is not that. Blender has full permissions as well.

Running latest MacOS Monterey 12.4, on M1 Pro Macbook Pro, with 1TB SSD/16GB Ram.

Edit: Appears to be saving slower, when I have Eevee higher quality settings enabled, but if basic view/solid mode, then savings basically instant.
