I asked Chatgpt this question:
hi, I created a new user in Mac, but why this new user can see the apps from other users? even the same permissions listed in the accessibility
It said:
By default, on a Mac, all users have access to the applications installed on the system, regardless of which user installed them. This is because applications are installed system-wide and are available to all users.
However, each user has their own separate user account and home directory, which means that their individual files and settings are kept separate from those of other users. Additionally, users can only access files and folders that they have been granted permission to access.
If you want to restrict access to certain applications for specific users, you can use the Parental Controls feature in Mac OS X. With Parental Controls, you can set restrictions on the applications that a particular user can access, as well as limit the amount of time they can spend on the computer, restrict access to certain websites, and more.
To enable Parental Controls for a user, go to System Preferences > Parental Controls and select the user you want to set restrictions for. From there, you can customize the settings according to your preferences.
