Hey Chris!
I really appreciate the instructions but I'm going to have trouble shooting this issue for a few reasons:
- I'm using my computer constantly for work, and can't work in safe more or on another user
- This issue is not directly reproducible and happens at unpredictable times, so I'd have to wait on safe mode for hours to see if anything happens, and even if nothing happens it wouldn't necessarily mean anything since it could have been that if I waited longer the issue still would occur.
I definitely restarted my computer a few times so I know that's not working.
If I could reproduce this issue by sending myself an email or something that would make troubleshooting much easier, but I cannot. I don't believe any more receiving emails actually triggers this. I sent myself one email at 11:43 AM and Mail popped up at 12:09. So I tried it again, sending myself an email at 12:10, but this time Mail didn't pop up until 3:14. And when Mail did pop up, the most recent email in my inbox was from 3:03 plus a few more in the preceding hours. Therefore, this issue is not reproducible, and doesn't seem to be related directly to when I receive emails.
And since you asked, the main email account I use is a gmail. I forward mail from all my other email addresses to my gmail.
I should also note this is my personal macbook pro, and I've had it since 2014. This issue only started a few months ago out of nowhere. Since it only happens every few hours its not the worst issue in the world, but I do worry my mail might pop open with some private email in the middle of a presentation or something and there's nothing I can do to stop this.
Thanks!
