--fix it changes nothing. Keys are shown masked: their first characters and last four.
--fix does the fix each finding carries, then checks again and prints what it did and what it could not do. It starts the helper app, or refreshes one that expired, on its own, and leaves it to Mobster for Mac when that is running. It names a program that holds a port, or a service that doesn’t answer, and asks before it stops it. It hands over to mobster login and mobster setup for what needs your answers. It never enters a passcode, runs sudo or downloads a runtime. Without a terminal, or with --json, it skips every question and says which.
