macos – Security implications of userid directory in / Applications



On macOS, root does not matter much as every user who is an administrator works with the same power. When you enter an administrator user and the administrator password in a permission dialog, any user (even a non-administrator user) does.

Some apps have a script or framework to change ownership to root, others do not change it (like when you copy an app from Downloads or a disk image)

The information you display makes no difference in terms of security. These are just permissions to a folder and package that anyone can read and execute. Other mechanisms check for known bad software and confirm that parts of the application have not been tampered with.
