AppInventor MAC user

I'm MAC OS Sierra 10.13 user and when i run the setup file version 3.0 the installation at the end says "successfully" but keeps making me reboot each time the machine without installing anything.
It the Apps folder i can see only folders and library files but no track of any executable file.
I will aprreciate any help

The setup tools package installs files into /Applications/AppInventor. It also creates a launch agent in /Library/LaunchAgents to automatically start aiStarter in the background when you log in, so there isn't anything you need to run manually, per se. After installation, you should be able to go to and start coding. Use either the Connect > Emulator or Connect > USB options to test your app.
