macOS - spctl command - disabled list with News.app - app still runs I followed the guidance in this answer.

Ran the following commands:

sudo spctl --add --label "DeniedApps" /System/Applications/News.app

sudo spctl --disable --label "DeniedApps"


News app (to be sure, this is the native Apple "News" app) can still be launched from the administrator account and from a regular user account.

As I understand it, the above commands should have been sufficient to stop the app from running.

Also tried a restart. No go. 

Mac OS 10.15.3
Ended up setting chflags hidden for the apps I wanted to block. 

Details are here (thanks to bogdanw):

Long and short:


First, with admin account create aliases to apps that will be hidden.
In recovery mode, set chflags hidden for app that are to be hidden.
