Sorry for my English, I'm French and I've given up trying to remove preinstalled apps like Tv.app and FaceTime. app.

I have tried a lot (even with SIP disabled) but nothing works. I'm kind very desperate since I’m not sure how I would set up screen time to limit my children’s usage of the Pre-installed apps.

The reason why I need to do so, is that my kid waste time in stead of studying. Is there a guide how to set this up?

  • Assuming the preinstalled applications on macOS Big Sur on an M1 are protected in the same way as on an Intel based Mac running macOS Big Sur, then they can not be removed with out breaking the cryptographically signed seal on the system volume. From what I've read about breaking the seal, it's not worth it! I'd leave well enough alone! – user3439894 Nov 22 '20 at 18:37
  • if I try this way:type: sudo mount -uw / type your log-in password (Optional restart if first try does not work) sudo reboot type: cd /System/Applications/ type: sudo rm -rf Facetime.app/ – user396819 Nov 22 '20 at 19:06
  • TV.app is 12 MB, FaceTime.app is 45 MB. Is it really worth going through all the hazzle for that? – nohillside Nov 22 '20 at 19:53
  • It's for my kid as he has to study on the MacBook but he can't stop using this apps and waste time – user396819 Nov 22 '20 at 20:06

The fastest path forward would be to make your account the administrator and grant each child their own managed AppleID and their own sign in and force them to abide by Screen Time limits.

You are correct that uninstalling the core parts of the system is a bit like the task of sysiphus.

You likely won’t even need to resort to stricter measures like a free / hosted MDM like https://app.jamfnow.com/devices

  • Where is no way by the terminal? – user396819 Nov 23 '20 at 4:15
  • Because when i had Catalina, I was able to remove all the apps protected by the terminal – user396819 Nov 23 '20 at 4:16
  • It changed from Catalina @Isabelle If it’s even possible, that way is no longer easy or fast. – bmike Nov 23 '20 at 15:44
  • can I back in Catalina with a MacBook Pro m1? – user396819 Nov 24 '20 at 3:10
  • @Isabelle No, Big Sur only for M1. – bmike Nov 24 '20 at 3:33
