When trying to connect to another Mac running Big Sur (beta 5) using file sharing (smb or afp), it won't accept the username/password. The dialog just shakes and won't connect.

I could connect from a Mac running Bug Sur to another Mac running Catalina fine but not the other way around.

Anyone got a workaround?

I have the same experience, except File Sharing does not work in the other direction, either. The connection is made, the volumes are displayed, but trying to access a volume fails.

Same here, absolutely impossible to share anything from Macs running Big Sur. Tried Catalina and Big Sur clients.

I have the same problem connecting from Mac running Big Sur to another running Big Sur, so I can't easily copy files such as Xcode 12 beta. My only option at the moment is going from Big Sur 1 --> Catalina --> Big Sur 2.

I was experiencing the same issue on the Big Sur Beta. On a whim I ran a fix for a file sharing vulnerability that Apple released quite a while ago and lo and behold it worked.

The following command fixed sharing for me:
Code Block sh
$ sudo /usr/libexec/configureLocalKDC

ACK, same here. First it was one way problem only (not able to access anything on network from my TDK), now -since the beta 6 update- it is I-directional.

Since latest I found that automator scripts to connect to a server do not work any more as well. What a mess.

This sort of thing can happen (authentication failures) if the system clocks are desynchronized.

Same here between 2 Macs running Big Sur beta 6.

Don’t get an authentication error, though - get a message saying “There was a problem connection to the server <hostname>. Contact your administrator for more information.”

Console shows error “netfs_GetServerInfo returned 5”

Can connect to the shares on both Macs from Windows 10.

Can’t connect from Mac to Windows 10; same error as above.

Same here. I can screen share, but not file share.

I has having exactly the same issue. Could connect Big Sur Beta (MBP) to Calatalina (iMac) but not the other way around. The post by kdubb- $ sudo /usr/libexec/configureLocalKDC worked perfectly for me. File Sharing now works like a dream in both directions.

Solution was to disable file sharing in System Preferences > Sharing on both macs, reboot, and re-enable sharing (also remote management if you had that on as well)

Hope that helps!

I had the same problem and this is how I fixed it:

-from the System Preferences screen, head towards the Users & Groups option. click the padlock, “Allow guest users to connect to shared folders”.
