Downloaded .dmg files will not mount

Has anyone filed an official bug report with Apple about this yet? I know there's a way to do it, but I can't remember how.

Should be able to do it here, selecting Bug Report in the feedback type pulldown menu http://www.apple.com/feedback/macosx.html

That's controlled by /System/Library/CoreServices/DiskImageMounter.app. Select a .dmg file, CMD+I, and see what's indicated under *open with.* If not that app, then select it, and click Change all. Now, double-click on a .dmg file and all should be well.

Spotlight won't find the Archive Utility (you can find it in a Finder search window, but only if you tell it to include system files). It should have been installed in /System/Library/CoreServices (along with DiskImageMounter).

It does sound as if your file associations are screwed up. Did you say that the "Open With" for .dmg files was showing "DiskImageMounter"?

You could try doing this, which resets the associations for all applications:

In a terminal window, type:

/System/Library/Frameworks/CoreServices.framework/Frameworks/LaunchServices.fram ework/Versions/Current/Support/lsregister -kill -seed

You may get a bunch of warnings after that about opening apps for the first time.

I have same problem. Holding cmd-opt-esc you can see the application listed but it's not running at all. with cmd-tab it's not showing up. I have to keep on deleting the 2 pref in the user/pref folder and relog. Any idea? The only thing I did was install 10.6 over 10.5.8. I also reinstall Stuffit Deluxe.

yea, since updating to 10.6.1 its now worse.

Dropbox is not opening for me, and jpegs with preview and Xee hanging in dock.

and the dmg files not mounting normally, i'm seriously considering going back to 10.5.8 😟

Add me to the list with this problem... Fresh install of Snow Leopard. The problem started before updating to 10.6.1.

I first noticed when trying to unrar something. unrarx just jumped for a while, then stopped but didn't do anything. I had to force quit and just sucked it up as a possible unrarx incompatibility.

Shortly after installing unrar via port so I could just extract the rar I needed to, I tried double clicking a zip file and Archive Utility did the same thing as unrarx.

At this point, I loaded up Disk Utility and tried to fix permissions thinking it was something weird like that but only a few Flash files were found. After I was done with that, I updated to 10.6.1 and restarted. Everything seemed to work again for a little while but the problem has come back.

I'm pretty sure this is a finder issue.. I've tried to open various different file types via finder and most of them have the same result. But I am also able to open up the application by itself and open the file from there just fine..

The applications that have stalled for me..

TextEdit, Xcode, Archive Utility, Preview, Firefox, Pixelmator, Transmission

While testing out the various file types, I noticed that some files of the same type would open from a different location.. i.e. An xcode project I have opens fine as well as all the files inside it's folder (png's, .h, .m, .xcodeproj) .. but the same type of files that I just downloaded and tried to open from my Downloads folder hang. Very strange.

I was wonder. People who has problem with applications not running when trying to open a document installed 10.6 fresh or over 10.5.8? I install over my 10.5.8 system, since I don't want to have to reinstall some of my applications.

has anyone had any luck solving this?
I have exactly the same problem, after a few hours of using Snow Leopard, DMGs fail to mount, zips won't open, clicking on files don't open the applications they should or the icons icon but just bounce forever... this really is a deal breaker of a problem 😟

Another person in the same situation here as well, running 10.6.1. Since some have been postulating that it's a Finder issue, I am (as I type this) downloading and preparing to install PathFinder, to see if it experiences the same issue.
