1.first try by double left click (default open with is DiskImageMounter) and i get "couldn't be opened" with reason not recognized
2.second open Disk Utility drag and drop name.dmg , select it , hit open button and get error mesage "unable to attach (not recognized)"
3. tried these commands:

sudo rm /System/Library/Caches/com.apple.kext.caches/Startup/kernelcache
sudo launchctl load /System/Library/LaunchDaemons/com.apple.kextd.plist
and retry disk utility and disk image mounter and nothing different happened
4. found many options here, didnt try cause they look scary to do with a new pc that is supposed to dont have problem like these described:
Procedure A.....
1. Navigate to and open.../Applications/Utilities/Disk Utility
2. Click on "Macintosh HD" in upper left, then press "Repair Permissions" .
3. If that does not solve the problem, navigate to /System/Library and delete...
Extensions.kextcache
Extensions.mkext
4. Navigate to /System/Library/Caches and delete the folder...
com.apple.kernelcaches
5. Restart and see if the problem still exist.
6. If that does not fix the problem, go to ~/Library/Preferences and delete..
Com.apple.LaunchServices.plist
7. Restart and see if the problem still exist.
Procedure B...
1. Navigate to .... /System/Library/CoreServices/DiskImageMounter .app
2. Drag the stubborn .dmg file onto DiskImageMounter .app
Procedure C...
1. Boot off your install CD and run Disk Utility to repair the filesystem.
2. Try to mount a dmg file using the unix hdiutil utility.
Procedure D....
Assuming that the disk image is on your desktop, try these Terminal commands:
hdiutil mount filename.dmg <enter>
where filename.dmg is the name of the disk image.
If there are an spaces in the name, use this form .....
hdiutil mount "file name.dmg" <enter>
Procedure E...
1. Navigate and open .... /Applications/Utilities/Disk Utility
2. If the .dmg file does not appear in the lower left pane, drag that stubborn onto the lower left pane.
3. Select that file ......(Command + Open) ..... The image file will be opened and placed on the desktop... Move that .dmg file to the Trash..So if you wish to add that file to your Archive for later usage, remove it from the Trash.
ProcedureF..
Download the free ....
Mount.app (http://mount.houchin.us/) software instead of the integral Mac OS X DiskImageMounter program within OS X. The Mount.app software which downloaded instantly then opened the.dmg file in question without hesitation.
so? any idea?
