~How…? 😅 We do not specify a custom symbol yet but have it on our roadmap (#8472). And I cannot reproduce this on macOS 26 Tahoe where I only see a plain default folder icon for the file provider domain in Finder. So a change in this regard is intended anyway but this appears to be a macOS behavior for now.~

@dannyrobertson Do you use the file provider extension (also known as "VFS") or the classic sync? Are you referring to the entry which shows up under "Favorites" (usual classic sync root folder) by default or "Locations" (where the file provider usually appears)?

[dannyrobertson]

Use the classic sync client. The icon I'm referring to appears under favorites in the sidebar. The icon style has changed drastically for some reason after the macOS upgrade.

Check out v4.0.0

[i2h3]

@AndyXheli Unfortunately that is not relevant for this issue because how the file provider ("VFS") defines its symbol is a completely different and independent story from the classic sync folder.

Thanks @i2h3 I did not know that! I marked my comment as off topic.

Same issue here. Using Nextcloud sync client 4.0.1 and MacOS Tahoe 26.

I can confirm this bug.

Any update here?

Same here. 👎

Since no one is responding here, how can we help? Do you need any support?

[i2h3]

I cannot reproduce this issue.

1. Downloaded classic files client 4.0.2 for macOS.
2. Freshly set up with an account to locally deployed Nextcloud Docker container. Note: classic synchronization, no file provider extension!
3. Standard folder symbol in the Finder sidebar on macOS Tahoe 26.1 appears. The folder was added programmatically to the Finder sidebar without any manual action by myself.

The only relevant log line I could find:

2025-11-28 12:59:54:978 [ info nextcloud.gui.wizard /Volumes/builds/35376/macos-35376/src/gui/owncloudsetupwizard.cpp:522 ]:	Setup local sync folder for new oC connection  "/Users/iva/Nextcloud"

Are @Rello, @mgallien and @nilsding aware of this issue? I am not familiar with the classic synchronization. Maybe Copilot has a guess.

I just tested it again. I’m using the Nextcloud Desktop Client version 4.0.2 (macOS). I open my user folder and drag the Nextcloud folder into the sidebar. Unfortunately, the display is still incorrect. I’m running macOS 26.1 (25B78).

Thank you for your help, Iva.
