trying to install several new apps (xbench, firefox etc) on the newly installed 10.4.4, downloaded successully, but when I try to mount the dmg by double click the dmg from safari download window, the mount always failed, the error msg is "device not configured", can anyone share some experience on this?

I had the same problem. What I wound up noticing was when I ran "Repair Disk" from Disk Utility on 10.4.4 there was A LOT of files it could not seem to correct ownership on. Here is the steps I took to resolve the problem:

 

1. Reboot into your 10.4.3 installation

2. Run Disk Utilities and Repair Permisions on your 10.4.4 drive

3. Reboot into 10.4.4

4. Repeat step 2

 

I think this most likely occurs if you import your ALL your files and settings from your 10.4.3 installation after your 10.4.4 install.

Hi,

 

thanks errandwolfe, this works perfect :D

 

you can also use toast titanium to mount the image, if t is urgent.

 

But of course it is better to repair permissions etc. ;)

errandwolfe, when i do this i get a no entrance sign when i try to boot 10.4.4

 

Strange... if thats thecase you could try to boot up 10.4.4. with -s, and then fsck and mount the disk (see the two commands shown right over your bootprompt in the commandline)

 

then do a sudo diskutil repairPermissions /

 

I CORRECTED THIS, THE COMMAND IS DISKUTIL, NOT hdiutil *sorry*

 

I hope that works :)

I hope that works :pirate2:

 

 

i get a waiting for root device msg and i can't get in to single user mode.

 

Going to try patch solution 1.0 cause i was still working on 0.3 and maybe there are some bugs that im running into right now.

hey guys!

 

I had the smae problem; nothin worked but then i found that:

 

 

I had downloaded some DMG files to install some software and kept

getting these error messages: Unable to attach "Foo.dmg" - Device not configured.

 

It was happening for more than one .dmg file, and I'm sure the

download was not corrupted.

 

At first, I tried using the Disk Utility, thinking it was related to

disk permissions, but the option wasn't present when I selected the

DMG. Clicking on "Verify disk" didn't help either, and resulted in the

same error "Device not configured".

 

Tried the instructions below and they worked.

 

1. Go into terminal

 

2. type

 

su [username that has admin rights]

 

you will be asked for your admin password.

 

3. Then run these commands. (I don't know what they do but they worked)

 

sudo kextunload -c com.apple.AppleDiskImageController

 

sudo kextload -b com.apple.AppleDiskImageController

 

4. Now try to mount those .dmg files.

 

 

this worked for me !

Best way is to find and deleting files below:

 

com.apple.frameworks.diskimages.uiagent.plist

com.apple.diskimages.fsck <- this may be the main culprit

com.apple.frameworks.diskimages.plist

 

may be problem with corrupt preferences.

 

Kextload and repair permission just temporary solve the problem for me

Is there a permanent solution to this yet? I updated to 10.4.11 and haven't been able to get images to mount. The temporary kext loads

 

"sudo kextunload -c com.apple.AppleDiskImageController

 

sudo kextload -b com.apple.AppleDiskImageController"

 

work until I restart. I tried Caminoz solution in his signature but it resets once I restart. This is the last thing stopping me from 10.4.11 being perfect. Help B)

Thanks, Captain Planet.

 

The above instructions worked perfectly for me! I just upgraded to 10.4.11 on my Dell Inspiron 1300 this morning.
