Apple Mail rules disappearing/unchecked/old ones reappearing after closing Apple Mail

Thanks for reaching out, LoboVerde.

It sounds like you're having some trouble with your Mail rules disappearing. We can help.

You mentioned that you thought there was a possibility that you might have removed something important related to your Mail rules. If you did delete or move system files, it can certainly have unexpected results. Let's go ahead and see if there are any updates for your Mac mini and make sure that you're on the latest software, but also that the software is complete: Update macOS on Mac.

Once updated, go ahead and see if the behavior continues.

Take care.

LoboVerde,

Got it. Thanks for checking to see if that helped.

Since you're still experiencing the same issue, we'd like to continue isolating this issue. Testing this behavior in safe mode is the first step. This will scan you startup disc and do a basic check. It will also delete some caches, and stop certain software from running as it starts up. We'd be interested to see if the Mail rules behave as expected at that point.

Let us know how that goes.

Hi LoboVerde,

A great way to isolate the behavior is to create another Administrator account and test it out. If needed, here are the steps: Set up users, guests, and groups on Mac

This will tell you if the issue is specific to one account or possibly a system-wide issue.

1. On your Mac, choose Apple menu > System Preferences, then click Users & Groups .

2. If the lock at the bottom left is locked , click it to unlock the preference pane.

3. Click the Add button below the list of users.

4. Click the New Account pop-up menu, then choose Administrator.

5. Enter a full name for the new user. An account name is generated automatically. To use a different account name, enter it now—you can’t change it later.

6. Enter a password for the user, then enter it again to verify. Enter a password hint to help the user remember their password.

7. Click Create User.

Best regards.

LoboVerde,

Have you had a chance to set up another Administrator account? If not, doing so would be the best way to tell if the issue is not account specific.

If the issue persists after trying that step, reply to this message.

Take care.

Great question, LoboVerde.

In both cases we would need to rebuild your users and preferences, just if its limited to your account it would only be one account to rebuild instead of all of them.

Hope that helps.

Take care.

It's up to your preference LoboVerde,
