plutil is a command-line utility used for managing property list (.plist) files. These files are commonly used by macOS to store a app settings and other configuration info. The utility allows users to check the validity of plist files
plutil -lint, convert plist files between XML and binary formats (plutil -convert), and add, modify or remove plist key value pairs.
Set app to run with dock icon hidden
plutil can be used to set the “LSUIElement” attribute to tue which will force the targeted app to run without the UI and dock icon.
plutil -insert LSUIElement -string "1" /Applications/TargetApp.app/Contents/Info.plist
