For the past few hours I've been pounding my head against a MailMate hang which I'm likely not alone with.

The latest batch of Apple Product Security emails caused MailMate to hang for me very reproducibly. I don't know the full explanation for why, but it has something to do with the GPG signatures on them. They recently rotated keys, so while I had many keys in my keychain for them, they were all expired. This shouldn't cause a hang in itself. The messages are structured as single plain text MIME objects including the signature, encoded by quoted-printable. This shouldn't cause a hang in itself.

I don't fully understand the hang. However, the fix was relatively simple: remove all the old APS keys from my GPG keychain, quit GPG Keychain, kill all of the orphaned gpg and gpg-agent processes you may have from failed attempts to open the problem messageand the process running /usr/local/MacGPG2/libexec/shutdown-gpg-agent (which starts at login.) Go to https://support.apple.com/en-us/102148 and copy the current key. Launch GPG Keychain, which will notice the key in the clipboard (if you copied it right) and prompt you to import it. Once the right key is in the keychain, MailMate has no problem with the messages.
