“Not signed by Apple”

[exegete77]

I have notices in App Store that four application updates are available. But when I click to update each one I get a notice: “Failed to verify the preflight file. Not signed by Apple.”

So what’s the story? Apple has updates on its own store, but has not signed the preflight file?So much for better update process and access.

Found this solution:

Launch Keychain Access, go to the preferences, click on the 'Certificates' tab, and make sure both of the options are set to 'Off' and not 'Best attempt' or 'Require if certificate indicates'.

Turning these off, I was able to download updates with no problems.
