How can I get rid of a Verifying Cisco webex meetings box?

Hi Morphologue,

We appreciate you reaching out to us.

We’d like to gather additional details that may help us be in a better position to assist you.

Have you had the chance to restart your MacBook Pro? Shut down or restart your Mac - Apple Support

If yes, please boot into safe mode, then restart the device and boot normally.

Safe mode does a basic check of your startup disk, similar to using First Aid in Disk Utility.

Performing this step may help resolve the issue, or further isolate the issue.

Below is an article to help guide you through the process.

How to use safe mode on your Mac

If the issue persists, test if you can replicate the issue on a newly created user account. 

Performing this step can help in isolating the issue.

1. "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."

Take care!
