MacOS High Sierra 10.13.2 causing Finder crash

Since updating to MacOS High Sierra 10.13.2 (from 10.13.1), I cannot connect to my NAS unit or other computers on the network, and in attempting to do so, Finder crashes and will not relaunch. I cannot find a fix to this problem, and as a consequence, my MacBook Pro (with TouchPad 2016) has become an island. I share files between computers on the network as part of my work process so this is a pretty big issue.

MacBook Pro (15-inch, Late 2016), iOS 10.3.2

The problem seems to stem from defaulting the connection to SMB version 3, which is somehow broken. Changing the connection string to CIFS:// reverts to the much slower SMB version 1. The solution to maintain relatively speedy connections and avoid the bug is to set the default connection to SMB version 2, instead. This will also maintain compatibility with Windows servers where SMB1 is disabled.

This answer from the JAMF forums seems to do the trick. Enter these two lines in the terminal. You will be asked for your admin password:

sudo echo "[default]" >> /etc/nsmb.conf sudo echo "protocol_vers_map=2" >> /etc/nsmb.conf

I just installed 10.13.3, Public Beta 4, and the problem appears to be resolved..So far I cannot recreate the problem..

Fingers crossed this is the last of it..

Does the new 10.13.3 version fix this issue?

Same issue here, 2014 iMac upgraded to 10.13.2 now finder crashes when attempting to navigate any SMB shares on our Windows 2012 server.

Only way to use Mac after that is hard reboot 😢

Apple please help us!

Had the same issue after installing the 10.13.2 update... I should have listen to my intuition not to install it after failing twice! It has been real headache to install the said update which has messed up big time and apparently many users...

Now I've seen some of the answers here below and you could also install macOS High Sierra 10.13.3 beta update, it worked out for me and stabilized the entire OS High Sierra system, but you need to subscribe to the Apple Beta program first! here is how:

Subscribe to Apple Beta:

Apple Beta Software Program

AppleConnect Sign In

enroll your Mac

Download Feedback Assistant:

Feedback Assistant

Do another backup with Time Machine:

How to use Time Machine to back up or restore your Mac - Apple Support

Once done then go to App Store and update the above mentioned update!

Let me know if it was helpful and more importantly, in a later stage if you have resolved this issue, as it seems that there are a high volume of issue with the 10.13.2 update, and it would be important to inform other users of a way to resolve it!

Good luck!

nothing works, 5 restarts since this morning.. and I was thinking it was my LAN... tried everything apart from downgrading the OS...

never again will I upgrade OS on my work computer... how many days do they need to fix this? to busy making animated poop head?

This change has actually sped up my connections and allows me to eject the volumes quickly. Before when I would eject with smb, the servers would get hung up and wouldn't eject until I logged off or did a hard quit with power button.

Dec 19, 2017 3:39 PM in response to lfuller105

I have the same issue. I am the lead IT Admin at my organization. I have followed the previous suggestions in this thread to switch to the CIFS protocol temporarily (very thankful for that suggestion), but as a much slower protocol, it has ground my entire marketing department, and any other media dependent users, to a halt.

This cannot go un-addressed. As a company we decided years ago to use Macs because of their bug-free nature, but lately our decision has really been challenged.

Just verified exactly the same problem with another machine (Macbook Pro), which usually is not used in office to connect to the shared directory on the Windows 2016 Server.

Apple if he hear us and care about using the Mac in a corporate environment, please urgently give us a patch to fix this problem.

Same problem! MacPro (Late 2013) Version 10.13.2... I should just get a computer running Windows, I went away from Windows because of all the bugs and now I'm dealing with this on my Mac. I can't get any work done, all of my data is on an SMB share.

Steve Jobs wouldn't have let this happen.

After several finder crashes and lockups, my system became unstable, coupled with a new issue - my Mac would no longer charge (the inability to charge has since been resolved). After several attempts at getting the OS back on my Mac with a clean build (it would hang with a critical error message, preventing installation) and loading my data back (no restore from Time Machine, simply copying of data), I am once again having the same Finder crashes when trying to connect via SMB to my NAS unit and/or other servers. This has been going on since December 8th after the update to 10.13.2. It is disappointing that I still see no viable solution on this thread or from Apple. I can transfer data using a Windows machine, but this option is hardly convenient.

For reference to everyone using Windows:

SMB 1.0 – The version used in Windows 2000, Windows XP, Windows Server 2003 and Windows Server 2003 R2

SMB 2.0 – The version used in Windows Vista (SP1 or later) and Windows Server 2008

SMB 2.1 – The version used in Windows 7 and Windows Server 2008 R2

SMB 3.0 – The version used in Windows 8 and Windows Server 2012

SMB 3.02 – The version used in Windows 8.1 and Windows Server 2012 R2

SMB 3.1.1 – The version used in Windows 10 and Windows Server 2016

How do you connect via cifs:// from the Finder? Shares that come up via smb:// produce the error "There was a problem connecting to the server 'Server'. Check the server name or IP address, and then try again."

smb:// mounts the share but replacing the prefix with cifs:// produces the error. Does cifs require mounting from the command line or can it be done from the Finder?

Dear andy72,

appreciate your detailed instruction. It works. A few days ago, tried to only disabled the signing only, which doesn't work. Forcing SMB2 by adding above command did the trick. Thanks a lot.

Jan 5, 2018 2:29 AM in response to gsonbroson

It didn't. At first Finder seemed responsive again and I had no problem opening all my folders again. But some disk operations (moving many / large files between my hard drive and the mounted share) resulted once again in the freezing of Finder. 😢
