How to restrict access to applications in Big Sur?
I personally don’t recommend blocking things that you as the administrator can unblock, but I understand friction can be good for many people so I would encourage use of screen time - if only to show you the amount of time you spend so you ca track that and build healthy habits over time. Also, it’s quick and easy so start with it while you wait for other answers to arrive.
- You can not delete apps in a meaningful way to accomplish your goal in Big Sur. It’s not easy and you have to circumvent the sealed system / patch and update process. Plus you may waste more time than you save in a week, but have at it if someone documents a solution there.
- Use Screen Time to block whole apps.
- Use the SelfControl app to block sites in Safari (and other browsers) https://github.com/SelfControlApp/selfcontrol/wiki/FAQ
Be sure you read the self control FAQ. It has some amazing gems of wisdom in it. Good luck tailoring your experience - don’t be out off by parental controls or screen time instructions - that’s the best way to block things without breaking the OS.
If you don't want to have access to FaceTime, simply Sign Out from FaceTime.
- Open the FaceTime app
- Select Preferences
- Click Sign Out
Then nobody can FaceTime you, nor you can FaceTime to anyone without logging in to the app again.
If you just want to disable some apps, create another user account without administrative privileges and then apply Screen Time restrictions to that account.
Likewise if there are multiple users sharing the Mac, create at least one user account per person and then you can apply unique restriction profiles for the respective user accounts.
