Software Update always crashes

Question

Everytime when I'm running the Mac OSX Software Update it crashes. I've this problem now since about 2 weeks. I tried to switch it to automatical update every ... days but that isn't doing anything at all. I always get the following error message:

Answer 1

Hi Stephan —
Sounds frustrating.
In the short run, you can use downloads directly from Apple's Download site.
To complement baltwo's excellent suggestion...
(I guess we're both presuming that you've already tried to open a "test user account" as a means to ascertain whether the behavior is limited to your user account, or systemic...)
A couple of ideas — general and ~specific — toward troubleshooting:
    (1)   My observation is that — in ~any situation like this — it's well worth the time to carefully review and follow all the steps that may potentially be relevant in both KnowledgeBase Article 106695: Troubleshooting Automatic Software Update in Mac OS X and 106692: Mac OS X: Troubleshooting installation and software updates. Most of the Softwatre Update and other download/installation-related queries I've read in Apple Discussions end up being solved by something discussed therein.
Hopefully, baltwo's suggestin or this will do the trick — and you can stop reading here.
    (2)   Looking ~quickly through your System Preferences.crash.log, the "machmsgtrap" entries jump out at me first thing. Quoting from the ADC document Examining File-System Usage: "Be aware that the machmsgtrap kernel routine will always be the system call with the greatest amount of CPU time used. This call indicates that the application is blocked and waiting for something to happen, such as a system event."
Thus, I've a pretty "geeky" idea — if you've the stomach to try it. If it's not already, move Activity Monitor's icon from /Applications/Utilities/ to your Dock. Launch Application Monitor. Set it to monitor "All Processes, HIerarchically," sorted by, e.g., Real Memory, most-to-least. Leave Activity Monitor open on the desltop — keeping an eye on whether any processes tend to "hang" (become significantly unresponsive — shown in red) even when you're not using Software Update (SU).
Then launch Software Update from the  menu, with the Activity Monitor main window positioned so you can watch it closely. As soon as the SU process shows up, double-click its name to open an "Inspector window" — also positioned for visibility.
Do you notice anything — particularly other processes — that may precede / be involved in the problem?
You may also want to look carefully through system.log &/or console.log entries whose time stamps correspond closely to the problem, as another means toward this objective.
Another really fun idea (ugggh!) might be to "Sample" (⌥-⌘-S) the SU process, starting before it "hangs" or "crashes" — again as a means to observe whuzzup. This will produce an incredibly dense amount of data — but there's a possibility you'll see something that'll provide a hint. There's a macOSXhint that provides an example of doing this.
I'd be interested to hear back about your progress...
Good luck!
Dean
