After the upgrade to Catalina, mail has become essentially unusable (2013 Mac Pro). Symptoms include extremely slow switching among different mailboxes. Extremely slow opening of emails and loading of same. 12 different email accounts, 2 exchange and the rest google. One of the things that i noticed is that both accountsd and mail have VERY high CPU usage, both hovering above 300%.
What I have done to try to fix:
Re-install Catalina
Deleted all email accounts and recreated.
Deleted Mail preferences / accounts preferences / related preferences
Disabled contacts syncing
Disabled calendar syncing
Reboot in safe mode
Nothing has fixed the issue. Mail usually ends up crashing inside of 24 hours. accountsd crashes about 50% of the time
A similar thing happened in the early Catalina Betas on my 2018 Mac Book Pro, but seemed fixed in the mid beta cycle.
Any ideas would be great!!
