The application Finder.app can't be opened.

The issue does appear to be as you all described (a zombie process) but your remedy of unmounting the disk through the cli didn't work for me. I even sudo'd myself to see if it would work from there and I get the same error.

bash-3.2# diskutil unmount /Volumes/Drobo
(null) was already not mounted

bash-3.2# diskutil unmount force /Volumes/Drobo
(null) was already not mounted

Yet of course the drive shows as mounted

//GUEST:@droboshare/Drobo on /Volumes/Drobo (smbfs, nodev, nosuid, mounted by myusername)

I'm a little hesitant about rebooting since I was working on something but I guess that is the only way to resolve this.

Message was edited by: Lane Campbell to add an image of the error itself

I wanted to report this problem as well. Trying to connect via AFP to Drobo via the BackMyFruitUp Drobo App.

It wasn't working, so I thought I'd manually connect via AFP to the share; it timed out so I force quit the Finder, leading to the error. Connecting to Drobo via SMB seemed to work.

Just to report that this happens to me too and it all started after installing 10.6.1.

iMac 24" (1 month old), 650GB, 4GB RAM,

There is no apparent reason why this happens, it just happens erradicaly at any time. I noticed that for system coming out of sleep this will happen 90% of times.

Count me in... ehhhh.... 10.6 has been awful, and now this after installing 10.6.1!

What a pain, this operating system is like being in ****. I KNEW I should have waited... NEVER again will I be a guinea pig for Apple, I've had it!

Same problem here. Please help!

I'm having the same problem after installing SL. I've discussed it elsewhere, but it's good to see it's not just me! I thought I'd cured it by binning some unused preference files, but after two days it's back again.
Everytime I read a gushing review of Snow Leopard I feel ill. Sure it's great when it works, but it's like having fast car that stalls all the time. Not what I expect on a brand new Macbook.

Ok, it just happened again here are some suspicious log entries:

ssh work fine and I can reboot through it, but no mouse clicks are being accepted!

and again and now I narrowed down system log that probably shows the issue to bellow. If anyone can provide hint on it now that would be great:

I too am getting 'The application Finder can't be opened' -10810

I got this because Finder was giving me the spinning beach ball as I was trying to access an external drive plugged in via FW800. After looking at the ball for 5 - 15 minutes, I do a right click on Finder and it says 'Finder not responding'. So, I restart it. That is when the message appears. No Time Machine back up (it is off), no SMB, no NAS drive (though one is attached - that was fine before the spinning ball of candy). I'm writing this on up in Safari with no Finder around. Cleanest desktop I've seen.

I've fixed my problem by downgrading SL back to 10.6.0

...disappointing...

Exact same problem here. Was trying to access data on an SMB external hard drive.

Rebooting now...

Same problem here, happened exactly as described in previous posts. I hope there is better bug checking next time, this is un-aceptable, alpha release kind of behavior.

"The application Finder can't be opened"

-10810

Add me to the list.
I can describe what happened and how it "fixed itself" for this one.
Went to sleep with an external driver powered on. Turned off the drive after sleep.
Woke up and started working for a few minutes and everything seemed find.
Actually connected to an NFS driver over VPN...like I said seemed fine.
Then I opened NeoOffice and it hung trying to bring up the open file box.
Then finder hung and so I forced quit Neo and Finder.
Finder didn't come back and I got the "finder.app can't..."
Solution: I turned back on my external driver and now everything is back.
I can avoid this situation, but let's all hope there is a fix for this soon.
Lastly, I have to agree that the Snow Leopard Update has been the worst I've experienced since moving to a MAC. ===SteveH

Greetings all, i have found a very specific finder crash....this problem has occurred twice in the past to days and is not repeatable, it tends to happen every few days or so. Select a file on a remote file server, control click on a file and select "OPEN WITH....", this results in the spinning wheel of finder death. the finder crashes and the only way to get it back is to power off the system by holding the power button. Force quit will not work and shut down times outs because the finder is "busy".

This started after I upgraded to SNOW LEOPARD and has not happened on my system in since I purchased it over a year ago.

Same problem here. Seems to be when trying to access SMB shares after putting my MacBook Pro to sleep.. Any thoughts?
