Suddenly, and probably since the 10.5.3 update, I've been unable to mount any .dmg files, and furthermore, I've been unable to open any .pkg files. Never had issues of this sort before.

When I try to mount any file I download it returns a "no child processes" error and when I try to open a .pkg file to install, the installer crashes returning an "installer quit unexpectedly" error.

I verified the HD and found some volume count errors. Booting in safe mode I repaired the drive and the drive was verified with no errors in disk utility after restart. I also repaired permissions with no success. The console logs crash reports for each instance in the console for both the mounting issue and the installer issue. I've tried setting up another standard account on the computer to see if it was account specific, but I received the same errors. I'm at a loss as to what to do to remedy this problem. Does anybody have any idea on how to fix this? Any help would be greatly appreciated. Thanks

system specs:

MBP 15'
Intel CoreDuo 2.0ghz
OSX (10.5.3)
512 MB Ram ( Definetly need to install the max..soon!)

I updated with the system updater. You think stuff got corrupted during the update?

Had the same problem with the wife's mini. Fixed it by downloading the combo update and reapplying the 10.5.3 update. Apple's deltas just keep getting worse and worse.

That's what I was planning on doing today. I couldn't do it since I couldn't mount or open the package, so I have the computer at work and am trying to commandeer a firewire cable to do a target install of the update. Hearing that it worked by re-applying the update on your end makes me hopeful that it will work on my end as well.

Well, I installed the 10.5.3 combo update to fix this problem using target disk mode. Resulte: the same errors and crashes. I don't know. I think I idid the install properly. It was my first time and after restart I really didnt get any indication that the install was successful to the target volume. The steps I took were:

-both host and target were on.
-connected both via firewire
-went to system preferences>startup, enabled target disk mode on target drive.
-restarted target computer.
-target computer restarted in target disk mode (firewire symbol was big and moving aaround the screen)
-Opened up 10.5.3 combo update on host computer and set as the install destination the target drives HD
- Installed
-message said it was installed succesfully
-ejected target drive from host computer
-powered down target computer
-unplugged firewire cables
-booted target computer.... tried to mount .dmg file... "no child process error".. tried to install .pkg... "the application quit unexpectadly"


I'm at a loss.

I guess the re-application worked after all. It wasn't working immediately after the target install, but after about 20 mins of the comp. being shut down mounting and installing .pkg files works fine now.

I was going to suggest you flush the caches and repair permissions, but it seems to be working for you now.

I'm not sure how to flush the system caches. Is there a good third party app. that you could recommend, or are you capable of doing it with what's available in the OS?

Kernel version must match the System.kext version.

If you are using a 9.5.0 kernel (from 10.5.5) then use the system.kext from 10.5.5

If it still doesn't work, extract seatbelt.kext from a 10.5.5 update and replace the one that 10.5.6 installed.

I'm having the same issue with iPC 10.5.6 install. When I open a dmg file, I get a kernel panic. I checked the kernel version and it says:

Darwin deans-p5q.local 9.4.0 Darwin Kernel Version 9.4.0: Fri Aug 1 21:34:49 EST 2008; ToH & StageXNU:xnu-1228.5.20/BUILD/obj/RELEASE_I386 i386


I checked the System.kext and it says:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com...yList-1.0.dtd">

<key>ProjectName</key>
<string>xnu</string>
<key>SourceVersion</key>
<string>12280520</string>

</plist>

The version numbers are matching so I'm not sure what could be the problem, help please.

Hi, I have the same problem.

I did a fresh install with iPC 10.5.6 and then upgraded to 10.5.7 following Netkas steps.
Opening any dmg will result in having to restart the computer.

Very annoying. Any hints?

Cheers.
