Hi ellenannbeck,
Thanks for contacting Apple Support Communities!
We understand that ProPresenter Presentation software unexpectedly quits while you're using it.
There are steps you can take to help isolate this behavior as outlined here: If an app on your Mac stops responding, closes unexpectedly, or won’t open - Apple Support
"Get more help
You can also test using the software in a new user account to help determine if this behavior is isolated to a single user or if it's system wide: Change Users & Groups settings on Mac - Apple Support
"Add account
Create a new user or group.
Click the New Account pop-up menu (you may be asked to enter your password), then choose a type of account.
- Administrator: An administrator can add and manage other users, install apps, and change settings. The new user you create when you first set up your Mac is an administrator. Your Mac can have multiple administrators. You can create new ones, and convert standard users to administrators. Don’t set up automatic login for an administrator. If you do, someone could simply restart your Mac and gain access with administrator privileges. To keep your Mac secure, don’t share administrator names and passwords.
- Standard: Standard users are set up by an administrator. Standard users can install apps and change their own settings, but can’t add other users or change other users’ settings.
- Sharing Only: Sharing-only users can access shared files remotely, but can’t log in to the computer or change settings. To give the user permission to access your shared files or screen, you may need to change options in File Sharing, Screen Sharing, or Remote Management settings. See Set up file sharing and Share the screen of another Mac.
- Group: Groups allow multiple users to have the same access privileges. You control a group’s access to your shared folders by setting access permissions in the File Sharing options in Sharing settings.
See Add a user or group."
We hope this helps.
Cheers!
