Does anyone know how the post installation process for those applications looked like (on first start)? Did a window pop up asking to accept the EULA and were you able to decline or was the EULA hidden behind some menu entry and using the application was consider accepting it? I'm asking because I haven't installed an app myself yet through the Mac AppStore which would explicitly ask me to accept any terms.
