Big Sur Beta 7 breaks SMB?

After the upgrade from Beta 6 to Beta 7 I am not able to connect to any smb-shares any more. I tried it with a Windows Server, Synology DriveStation and a Debian implementation. I'm directly getting the message Error with connection.

Unredacting the logs reveals the issue, insufficient permissions to load the kernel extension. Just run this (once):
sudo kextload /System/Library/Extensions/smbfs.kext

Apple Devs: So no SMB in Beta 7
Apple: Run this.
Apple Devs: um....
Apple: yeaaa.
Big Sur Beta 7?
i have always the same problem. MacOS BigSur Beta 20A5364e and my RaspberryPi Samba Server didn't connected. VNC and Appache are running well. I have the latest updates from RaspIO 32 Bit and RaspIO 64 Bit.

OK => open terminal tipe su for the root and password
copy -> sudo kextload /System/Library/Extensions/smbfs.kext
and type password.. it runs
thank you. my smb is back.
This solution seems to be renewed every time you restart. Is there any fix solution to that problem ?

Thank you! Worked perfectly!!
Even i too had the same issue with my SMB CIFS share running in my raspberry pi.

I had added my SMB share as part of user login process. and also having a file share discoverable by my mac time machine for backup.

After Mac Big sur update it fails saying cannot connect.

But i had a different workaround, on time machine if i initiate a backup then trying to connect to SMB works for me. but again this goes away after restart.

is the Mac Big sure team working on to fix this issue? i had sent a feed back too.
This saved me big time. Thanks y'all!
Thank you, this fix worked for me
It does work for me as well, thank you!
Thanks. This worked for me!
Amazing, given we're only on Beta 6 and 7 hasn't been released?
Thanks for the workaround..... As of Beta 7, the bug still exists, and it's boot to boot.


Adding this AppleScript to your Login Items will fix it at login until Apple fixes it:

Code Block
do shell script "kextload /System/Library/Extensions/smbfs.kext" user name “name” password “pass” with administrator privileges


Thanks! Worked with sudo kextload /System/Library/Extensions/smbfs.kext
It seemed that it was fixed on beta 7.
Thanks!!!
worked for me thanks !
My SMB-not-connecting issue got fixed with the latest beta: 11.0 Beta (20A5395g) (the same issue that was previously fixed with the command-line string that another user posted)
I am experiencing the same issue (11.0.1) and the proposed solution doesn't work for me.
I have the same issue, but I've noticed that happens with servers with Windows Server 2008. With more recent versions it works.
The commands are not working for me. I have 2 other MACS that are using ElCapitan, and Catalina, and they both are able to connect to SMB Synology share CDMSNAS but the Macbook Air with Big Sur 11.1 does not see CDMSNAS on the network, but if I do the Go to Server and enter the smb://IP address, it sees it fine.

When is this going to be fixed. I am very disappointed in this release so far, entirely too many problems.
