MacOS rearranging windows across displays after sleep

Hey Carlos2o1,

So it looks like safe mode fixes the issue temporarily but the issue persists. Do you have multiple user accounts? If yes, did you get a chance to test it out with other accounts too?

If it happens with another user account, we recommend that you reach out to Apple Support next: Contact Apple for support and service

To create a new account if you don't have one, check out the steps below:

Add a user or group on Mac

Add a user

. On your Mac, choose Apple menu  > System Settings, then click Users & Groups  in the sidebar. (You may need to scroll down.)

2. Click the Add Account button below the list of users on the right (you may be asked to enter your password.)

3. Click the New Account pop-up menu, then choose a type of user.

4. 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.

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

6. Click Create User.

We hope everything works out!

Best regards.

Hey there Carlos2o1,

That's an interesting issue you're having, and we'd like to help however we can. Let's start with ruling out some possible causes, along with confirming more details to better understand what's happening:

1. When did this start to occur?
2. Sometimes unexpected behavior can be resolved with a restart. Check out the section ‘Restart your Mac' here: Shut down or restart your Mac
3. We see you have macOS High Sierra installed, but the latest for that older version would be macOS High Sierra 10.13.6. You can verify this by clicking on the Apple logo at the top left corner of the screen, then on ‘About This Mac’. In case you needed it, this link shows how to first back up, then Update macOS on Mac.

Cheers!

Hello Carlos2o1,

Thank you for reaching.

Did you contact the support?

wish you good luck,
