EULA agreement Mac 10.11 freeze

I’m trying to install any version of Sketchup Pro/Make 2015/2016 but the same issue keeps coming up: whenever I want to check the EULA box in 2016 or click on EULA agree in 2015, sketchup just shows the wheel of death. I have tried with several versions, also cleaning the library after each try and restarting the system. Without success…
Any ideas?
