  2. Mac Os Update Won't Download

Dec 26, 2018  Mac users have recently begun to run into an issue that prevents them from using MacOS effectively: When they try to turn their Macs on, they get a message that says, “A critical software update. Apple is now distributing the latest upgrade to Mac OS X, v10.5.5, through Software Update. The patch addresses a considerable number of aspects in the operating system, such as Mail, MobileMe and Address Book, as well as some 'general' concerns, according to Apple's support notes. Some of these i. OS X Mavericks v10.9.5, OS X Yosemite v10.10.5, and OS X El Capitan v10.11.5. OS X El Capitan v10.11.5 and Security Update 2016-003. OS X El Capitan v10.11 and later. WatchOS 2.2.1.

Mac Os Update Won't Download

Greetings.
I just recently had my eMac in for a new logic board. It came back yesterday, and I've been playing around to make sure everything seems okay.
The only trouble I am finding now is with Software Update. My computer was in the shop for quite awhile, and when I started it up yesterday, there were four items to download - 2 security updates, and the new iTunes and Quicktime. Each time I try to download, at it's conclusion I get the message 'Software Update could not expand the package correctly', with the red exclamation point. I have tried several times, with no luck. Finally, with all but the iTunes, I had to download and install from the Apple website, which was successful. I am saving iTunes as my test case.
I see this workaround from Frakes and Landau on Peachpit.com:
'You may get an error message such as one that says, 'Some of the checked updates couldn't be installed. Software Update could not expand the package correctly.' In the Software Update window, an exclamation-point icon will appear to the left of the name of each update that was not installed. If this happens, remove any package and receipt files for prior versions of the problem software (prior updates to iTunes, for example, if that is what you are updating) from the /Library/Packages and /Library/Receipts folders. Then try again. Otherwise, choose Download Only, to have Software Update just download the update package to your Desktop. Then double-click the package to launch Installer, which will hopefully succeed where Software Update failed.'
I have tried this, to no avail. (by the way, there is absolutely nothing in my /Library/Packages folder. Is this normal?). I have also trashed every Software Update .plist I could find, but nothing helps.
Does anyone know what is going on, or how to resolve this?
Thanks in advance
edit: here is the console.log, if that helps:
