Hi, montana in a jeep!
Thanks for stopping by the Apple Support Communities. I understand from your post that there are some apps in your Dock that appear with a red slash through them, and you can't delete them. I'm happy to help!
From what you've described, I suggest going through the following steps. Try them in order, testing after each until the issue is resolved:
- Quit any open apps: Quit apps on Mac - Apple Support then restart your Mac: How to turn your Mac on or off - Apple Support.
- See if the issue occurs in safe mode: Use safe mode to isolate issues with your Mac - Apple Support.
- See if the issue occurs in a new, test user: How to test an issue in another user account on your Mac - Apple Support.
Don't hesitate to respond back if you still have trouble with the apps. If you do, please provide additional details about your issue, including where you're trying to remove the apps from exactly, and what happens when you try to remove the apps from them. If you get any error messages, what is the exact message you get?
Enjoy your weekend!
