Recently, everytime I attempt to open the software updates under the Apple menu, it begins to load, then shuts off with the warning that it failed to launch. What can I do to fix this?
Try repairing permissions. Finder--->Go--->Utilities--->Disk Utility. Or press shift+command+U from the finder to get to the utilites folder. If that doesn't fix it try resetting the P-Ram.
Restart the computer and hold Option,command,P,R and let it chime two-three times.
This happen on wireless or cable? I have it a few times do this when i have been on wireless - very strange
To repair disk permissions you need to select the drive or volume you want to run the operation upon. In this case, simply select Macintosh HD from the left side, and make sure the tab is set to First Aid. You should have the 3 available options for verify disk permissions, repair disk permissions, and verify disk. The last one for repair disk is not available unless you are booted up to the software disc or to an external drive. Instructions for resetting PRAM can be found @ http://support.apple.com/kb/HT1379. Resetting the PRAM isn't a really viable solution for this problem, more than likely it's something software related that only Disk Utility or reinstalling the OS or applying an update will fix. If you are not running 10.4.11 or 10.5.6, or rather you know what updates you are missing, download the update directly from www.apple.com/support/downloads instead of waiting for the automated software update to be fixed.
