I have two Macs both with Max chips and on Monterey 12.4
I believe both Apple Mail accounts have the same settings and same smart folders synchronize through iCloud.
One computer open apple mail Super fast (ethernet), and the other computer takes about five to ten seconds (fast wifi - 20% slower than ethernet) to open apple mail.
Does anyone have any suggestions how to fix the slow Apple Mail app? Rebuild mailboxes etc.?
I’m on a M1 MacBook Air, and I also experience slow startup of the Mail app. Mine takes anywhere from 1–2 minutes to open. After that, the app is responsive and works well, but it sits and pretends to beachball while opening. I’ve tried a bunch of “tricks” to get it to work, but nothing ever seems to fix it. However, I do feel like it has to be a software bug somewhere. It just started in the last few months. Typically I’m using MailMate though, so it’s never really an issue.
I have the same issue. I thought it was related to GPG Tools, since it showed up a couple weeks after installing it and some other users have mentioned similar issues, but removing GPG Tools had no effect, and there’s no GPG Tools bundle as mentioned here.
I tried removing all accounts and re-adding them twice, the second time I deleted everything in ~/Library/Mail before re-adding my accounts. And I tried to turning off iCloud Private Relay in Mail’s privacy settings, based on how Safari has issues with it enabled sometimes. No dice.
This also occurs for me, and I’ve seen it on both my home and work laptops. Deleting all the attachments with CleanMyMac helped speed it up a bit it is still around 10 seconds to launch.
I’ve seen the exact same thing with my Mac Studio. I think it’s always been like that since I migrated, but it might have been faster in the beginning.
The application seems to launch instantly, but it takes at least 10 seconds for any windows to appear (Message Viewer or individual messages I’ve left open in their own window). It’s annoying, but it doesn’t seem fixable and it doesn’t seem like it’s damaging data.
Edited to add: I’m not running any Mail plugins/extensions.
I had a DEVONthink plugin that was actually disabled. I enabled it, restarted mail, then disabled it again, and now Mail (for now) launches lightning fast.
DEVONthink plugin - can you tell me which one? (I bought DEVONthink but haven’t done much with it yet - I want to do whatever you did to see if that fixes things also)
