Finder keep crashing on Mac Os High Sierra

Have a close problem to yours

When I connect to windows server at work, Finder just crashes.

Scenario - shared server is visible, I can see files, but as soon I try to do something Finder crashes and never get working again. Even after relaunch. And I can't even shut down computer properly, only with holding the power button.

Got a solution for half a day - shutting down Windows firewall on the server. But the next morning I have the same problem.

This only seems to happen to me when working with SMB shares at work so thanks for mentioning that where few others have. Interesting that I tried force-quitting/relaunching Finder and it won't fully relaunch. As you say, a hard reboot is required. Since I have 4 virtual machines running various test processes, this becomes nearly impossible! I guess I need to stick to using one Win10 VM for connecting to the SMB shares. Crazy! This wasn't happening until the last security upgrade.

You might want to upgrade your system to 10.13.3 beta 5 (came out today) that seems to have solved quite a few of my issues. It's available to now to anyone if you sign up. Try it on a least concern computer.

So in my case (which I explained above) I am half-way with the solution

What I did

- cleared Finder preferences

- connected to server with cifs://192.xxx.x.xxx instead of smb://192.xxx.x.xxx

Connection worked, but got lost again

- switched off Windows Firewall off again

Everything works

- updated to last Public Beta

seemed to solve the Finder crashing issue (tried to put back smb connection, Firewall on, didn't connect, but didn't crash)

So now need to figure out what changes should be made in the windows firewall settings. Because at one point switching it on and off made it to refuse connection also for Win machines now. At the first glance everything looks ok.

Out of curiosity, why are you using Windows firewall in a LAN environment? I find it only causes problems, not only for Macs but also unexplained connection issues for Linux and other Windows computers. Surely you have a firewall for between the LAN and the WAN, right?

@User462. I probably shouldn't have either but users were complaining so much that I pretty much had to if there was a fix. I justified it in my mind that 10.13.2 was just a beta and these all are a step in the right direction.

why I use Windows Firewall...

actually, no reason at all.

Setup for this office is the most basic in the world:

1 Win10 PC with LAN connection to a 4G router. This is used by a one guy for work and stores files for everyone, so is a server

3 Win 10 Laptops that are there from time to time

1 Macbook Air

All laptops use/modifies/works with files on the server

Are you suggesting to try some other firewall?

I am suggesting turn the firewall off for the LAN. Microsoft put it in for those people who are out "in the wild" all the time as the default. Probably not a bad assumption, but when you are in a LAN there is no purpose and you just have to poke holes in it so you can get work done. If you have a good router with a firewall to the WAN, then you are good.

I am the only Mac in a Windows office - and I usually don't have any problems. I thought I waited long enough to upgrade to High Sierra, but almost immediately was getting the Finder crashes over the SMB connected servers.

Changing from SMB to CIFS has worked for me and it all seems to work fine - no more frustrating Finder crashes! It's not slowed down production either.

I'm happy to use this method until 10.13.3 comes out.

>>Apple should listen more to the community to help solve all the bugs and issues. *JUST WISHING*<<

Have you filed a bug report? If you have not, they have no reason to listen. It's very easy to go to bugreport.apple.com

They have setup a means for you to communicate with them and this forum is not it. This is for user to user only.

File the bug report. It's simple and they usually respond to you. If they don't they will let you know that it's an issue they are working on and set it as a duplicate case.

Same problem here with High Sierra 10.13.3 and IMac 27" late 2012.

I did reinstall everything last autumn and quite a long time had no problems.

Now Finder is crashing 2-3 times a week. Very annoying!

Does Apple have any fixes on this??

Yep mine crashes all the time too, especially when I plug in media (USB stick, camera card) or when I do something with my networked timecapsule - endless beachballs, very annoying. Apple, get on top of you sh*t, the stability of your OS is going downhill faster than an englishman after a wheel of cheese.

I have the same issue. I noted today that there were two instances of an external drive listed and find went into unresponsive when I tried to eject the second.

But this happens once or twice a day and the only way to fix it seems to be a hard reboot. It's been happening for months.

Same here. What is the solution?

so far has not popped up.
