Apple’s latest update to Mac OS X, 10.5.6, has been causing several problems since its release last week. The Bluetooth glitch comes to mind immediately. An even more serious glitch, which causes the download to stop halfway, has been addressed by Apple on its Support site.
Should your Software Update malfunction, you’re advised to restart your Mac (by holding down the power button if need be) and delete the partially downloaded folder, which is found in /Library/Updates. You can then attempt to update. Fingers crossed, it should now work.
Yet another reason to let at least a week go by before updating your OS X installation.
