I am having trouble mounting DMG disk image files after upgrading from OSx86 10.4.3 to 10.4.4. Neither double-clicking the file nor a mount through Disk Utility work. All I get is a small window labeled "Warning" notifying "Reason: Device not configured". I guess it is a permissions problem - however, repairing the permissions on the startup volume (which returns A LOT of "crap messages"* both in Disk Utility and Terminal) doesn't solve it (or should I better say: the repair won't work at all...) - I've tried this logged in as user (with admin rights) and root as well.

Anyone? I should mention that I installed from within a working 10.4.3 8F1111 install (which I have made a backup of, just in case this DMG problem persists in 10.4.4) to a fresh HDD, using Base Patches v0.3.

* e.g. for a "crap message": Owner and group not corrected on -=DIR/FILENAME=-, reason Operation not permitted (this is what it says in the Terminal window after a "sudo diskutil repairPermissions /" - so I guess the permissions repair doesn't work at all for me right now... see? crap! ;) )

Any help on this is very much appreciated.

Hi,
repairing permissions on the 10.4.4 disk from my 10.4.3 install solved this problem.

YIPPIEH! success :blink:

Thank you cat_7, combined your findings with the hints mentioned in this post here by errandwolfe - that did the trick for me! I simply booted back into 10.4.3 from my USB/FW system backup HDD, did a "sudo diskutil repairPermissions /Volumes/<10.4.4-VOLUMELABEL>" twice (no "crap" this time), and then back in 10.4.4 I did the same thing once again to make sure. Great - I love this forum!

This problem may also occur after a system crash. In some cases the Disk Utility is unable to repair the specific permissions for mounting correctly. After googling for a while I found a proper solution. Here it goes:

1) Fire up a terminal
2) Try mounting the dmg from terminal like this:

hdiutil attach -mountroot /Users/yourusername/Desktop/ filename.dmg

If errors occur, set the correct permissions for hdiutil manually like this:

sudo chown root:wheel /usr/libexec/load_hdi
sudo chmod 4555 /usr/libexec/load_hdi

3) try again: hdiutil attach -mountroot /Users/yourusername/Desktop/ filename.dmg

Now everything should be fine...and you can mount .dmg files from finder again...

:pirate2: another prob solved... have a coffee & rock on!
