Do I need an administrator password to install Storage Studio?
Short answer: No — dragging it into Applications needs no admin password. macOS may ask for your password later for protected actions, such as changing Full Disk Access or removing an administrator-owned app.
Not to install it. Dragging Storage Studio into Applications doesn't ask for an admin password, and if you can't write to the main Applications folder you can use the Applications folder in your home folder instead.
You may be asked for your password later for specific actions macOS protects — for example, granting Full Disk Access in System Settings, or removing an app that macOS installed with administrator ownership. Storage Studio always shows you what it's about to do first.
