Hi there! I understand how annoying it can be to deal with unwanted ads popping up when you open your camera app. Let’s work through this together to find a solution.

1. Check App Permissions: Sometimes, apps misbehave due to incorrect permissions. Go to your System Preferences on your Mac:
- Click on Security & Privacy.
- Under the Privacy tab, check the permissions for your camera app. Make sure only trusted apps have access.

2. Update Your Apps: Make sure your camera app and all related software are up to date.
- Open the App Store on your Mac and check for any updates available for the camera app.

3. Remove Recently Installed Apps: If the problem started after installing a new app, try removing it:
- Go to Finder, select Applications, and find any recent installations that might be causing issues. Right-click and select Move to Trash.

4. Check for Malware: It’s also possible that malware could be causing these ads. Consider running a malware scan:
- You could download a reputable antivirus software to check and clean your Mac from potential threats.

5. Disable Notifications for Ads: While it’s not directly related to the camera app, you can manage notifications for apps that might be showing ads:
- Go to System Preferences > Notifications and adjust settings for any apps that seem to be involved.

If you’ve already tried some of these steps or the problem persists, please let me know, and we can look into further advanced troubleshooting or contact higher-level support if necessary. Are you satisfied with the solution I provided?
