OS X Software Update broken due to expired SSL certificate →

If you try to run updates via the Mac App Store today, you will more than likely see this message:

The certificate for this server is invalid. You might be connecting to a server that is pretending to be “swscan.apple.com” which could put you confidential information at risk.

Arnold Kim explains:

Swscan.apple.com is one of several servers that Software Update uses to communicate with Apple. The apparent problem is that the security certificate for the server appears to have expired. The certificate was originally valid from May 22, 2012 to May 24, 2014.


It’s this sort of thing that doesn’t do much for my confidence in Apple’s ability to handle services well in our cloud-centric age.

(Don’t even get me started on having to use the Mac App Store application to update system software.)
