MailMate hangs when opening up after a restart (MacOS 12.2.1)

R5876 had the same issue. I thought it may have been related to IMAP Server setting but it doesn't jibe since it previously worked! Nevertheless, I went ahead on the proper setting of IMAP (incoming) and outgoing server settings, both "mail.icloud.com". Also entered the App specific key.

The gear next to the account name still spins endlessly, however it doesn't fail over. New mail doesn't appear at the inbox. Anything else to do? I will be forced to go back to Mail.app and see if the problem exists there (doubtful. In any case this is a no-go for me. Cannot continue with MailMate.

I believe the settings should be imap.mail.me.com/smtp.mail.me.com, but it sounds like the crashes are not related to that. Either it's triggered by the arrival of a message or by some local change that MailMate tries to synchronize with the server. This only happens when the account is online so I would expect the crash to return when the account synchronizes.

It should, of course, not happen, but there's been a lot of changes in the test releases the past few months. I've fixed a lot of bugs, but the hard ones are usually related to hard-to-reproduce issues like this. A hang report will help though. Can you, e.g., send it using Help > Send Feedback when the iCloud account is offline?

It's naturally also fine if you do not want to waste time helping me debug. I'll provide a refund and get out of your hair (might not be using that expression correctly given that English is not my native language).

(I've unfortunately given up on freeing up quota in this ticket system because it usually only takes a couple of days before it's full again. It's simply easier to handle attachments by email.)

Continues to hang, even in recurring attempts to use r5876, opening the general All Inboxes mailbox. Wake from sleep with app running, click a mailbox>spinning beach ball.
Error report also sent to Apple by default. The last somewhat reliable build was r5874. Should I go back to that?

Unfortunately I do not get what is sent to Apple. This only works for apps part of Apple's App Store. I need you to send me a hang/crash report directly.

I suggest first trying r5878 and then r5874. Then maybe go back to the latest beta to see if that works: r5852.

Note that r5876-r5877 are known to be unstable (fixed yesterday for r5878).

In r5852, after the hang, I cannot log in with an older app, even r 5852 until the error times out again. That may be as long as 48hrs! Luckily, Mail app still has no trouble logging in.

It still seems that the problem is with the INBOX folder as the items in the folder cannot be deleted in MailMate. That doesn't happen with other apps like Mail. Everything seems normal there.

So, something happens in MailMate that messes with the Inbox of that account, not with others, then it takes a long while to reset itself. Unknown as yet if r5852 will have an issue likewise. If this release which used to work fails, then I will have no choice but to go back to Mail until such time as it's fixed. If its an iCloud compatibility/connectivity issue then we'll have to reassess.
