Initial 10.5.7 update issues: Unable to download.

Several people are having troubles downloading the update. When they try they get an error claiming the digital signature for the package is incorrect.

"Has anyone been able to download it successfully? I've made three attempts, and every one of them has failed with an error message telling me that the digital signature for the package is incorrect, suggesting that it may have been tampered with since being signed."

This is more than likely an error at Apple (which hopefully will be fixed quickly) and nothing to do with the update being tampered with, but to be safe, try updating by using the combo or delta updaters (links below). You might also try updating after downloading them and booting into "Safe Mode" (holding shift at bootup) to ensure no third-party software interferes with the update process. Running Disk Utility to repair permissions and check the drive for errors both before and after updating is also recommended.

Download locations:

• Delta Updater
• Combo Updater

Other problems you might be experiencing are slow downloads. The update weighs in at over 400MB, and with everyone downloading there may be periods of slow-downs (our current download progress claims about 4 hours left...ugh).
