Once in a while Finder stops connecting to SMB shares.
Finder → Cmd+K → Connect → It shows a window like this infinitely:
What I've tried already:
- I have tried connecting to multiple shares (Linux, Windows), Finder didn't connect to any of them
- Connecting with an alternative client works. For example, Kodi media player includes its own SMB client and it connects just fine.
- Connecting from other running Mac works too
- Reset Finder settings by deleting
~/Library/Preferences/com.apple.finder.plist
- Kill Finder with
killall Finder
command - Add username and password explicitly into the Cmd+K connect to server dialog:
smb://myusername:[email protected]/MyFiles
I assume this is a macOS SMB client issue.
This issue will go away with a reboot. I'd like to fix the issue without restarting macOS – how can I restart SMB services only?
mount
in Terminal. If there’s already a connection to the server, try unmounting those volumes and then try your mount againmount

while booting)? Also, if possible, install an earlier version of macOS (don't wipe your internal drive!) to an external drive (flash drives are cheap now) and boot from that and see if the problem goes away. You're not reinstalling macOS, just putting a different version on a removable drive for testing. I have a suspicion it's an issue with Catalina.
