Q: Mail encryption buttons missing in Sierra, unless Mail is restarted
This question regards a MBP early 2015 running Sierra. Apparently since the upgrade, Mail has become very flaky with encrypting emails. The buttons won't show up--UNLESS I start a draft email, then restart Mail. Upon restart, the buttons are back. BUT, change the email sender or recipient, and the buttons disappear again. This problem applies to all recipients I have certificates for. Create a new email, same problem until the app restarts. Sender and recipient keys appear intact. I have an iMac that is setup nearly identically, and is not having this problem.
I have tried erasing preference files mail.com.apple. I have tried restarting computer, and reinstalling my certificate.
Seems to me like some minor file somewhere got corrupted, but I don't know what other files I can try to eliminate to try to fix the problem. Any other suggestions? Thanks!
