I'm experience some issues with my Mac Mail on my MacBook Air. I hasn't been there all the time, as far as I can remember it started around Yosemite.
In my mail, I've two accounts. One is my work mail which is an IMAP for Google Apps gmail and the other is my private mail which is just a standard Gmail, also with IMAP.
On my private mail I've two-factor turned on, while this is not the case with my work mail.
Now, seemingly random my Mac Mail gets non responding and I've to hard quit it and reload it. It has something to do with the synchronizing and my private mail but can't seem to figure out what.
I hope someone has a solution or has experienced this before and know what to do. I rather not turn of two-factor of my private Google account if I can avoid it.
Cheers
