MacOS High Sierra 10.13.2 causing Finder crash

I've installed 10.13.3 yesterday and had no problem since installation.

Seems to be fixed.

if the issue is somewhat related to the SMB version and if it is related to smb v3 than you could try to add :

protocol_vers_map=2

to your nsmb.conf.

This would force smb version 2.1 instead of cifs which is smb version 1.

you can verify the connection protocol using "smbutil statshares -a" in a terminal.

I tested it now with my mac and it is seems to work as cifs with no crash, maybe the protocol is faster.

After a few weeks of constant hangups this solution finally gave me a working Finder again. My problem arose due to the combination of 10.13.2 and Google Drive File Stream that was mounted as a shared disk.

I'm keeping my fingers crossed this will keep working smoothly now.

I can only recommend downloading the Path Finder 30 Days trial version.

It works similar, on top of the systems Finder. Use it as a replacement until macOS has been patched.

Path Finder does not have any problems with network shares on macOS 10.13.2!

I guess it's not only the packet signing because the other modification changes the protocol version to 2.

In addition, and sorry for not mentioning it earlier, I also use cifs:// instead of smb:// to connect to my file servers.

I changed to CIFS and this also solved the problem. Didn’t need to reboot in safe mode. Agreed it is very slow.

Connecting with cifs:// instead of smb:// worked for me for mounting Windows shares. No more hangs.

Thanks for all this feedback..We too are seeing the same issues both with Windows Server 2016, and 2012 R2. The problem does not exist when connecting to Windows Server 2003 R2, or on my NAS for that matter. A short term bandaid for us is using the cifs protocol as suggested. 10.13.1 is fine as well. I Actually rolled a few Macs back to Sierra in the interim as well.

It seems that this is only happening when I access my NAS shares outside my LAN through a L2TP VPN connection. Now i'm working at home connecting directly to the share and it has been working ok for the last hour. Yesterday, through VPN, my MacBook would crash after 5 to 10min going through the folders on the remote share...

The only the that has consistently worked for us is to mount the shares via cifs://

CIFS is indeed much slower than SMB. As I sync many files over the network, just unacceptable for me.

Please have a look at the solution workaround from andy72. It works well for me.

You're saying the 10.13.3 patch fixes the SMB and finder hang problem? Please tell me it is so!!!

Several reports seem to indicate that it is indeed solved.

Thanks for this. No idea why, but after the safemode login, i could also use my SMB mount path.

Same here - we have 50+ Macs over 8 sites connecting to Windows 2012r2 servers and we are having it all over. Major fail in the latest update.

Ive deleted login items from startup. deleted the keychain, deleted any shortcuts and reset the smb mounts to share but it will still happen sporadically.

Major Fail from Apple and if it doesn't get patched we are going to have to roll back to Sierra.

I'm experiencing the same issue.

I'm forced to restart my Macs in order to regain Finder functionality. This is only a temporary fix - until Finder crashes again (Finder crashed at least 6 times today on my MacBook Pro; 5 times on iMac; 4 times on Mac mini)
