I HAVE A WORKING INTERNET CONNECTION AND A GOOD ONE.


Is anyone facing the same issue ?

Is there any other source of downloading support dmg's for android / ios and other platforms ?

Have they resolved it ?

Attaching screenshot

Thanks

 

>> Is anyone facing the same issue ?
I had the same problem with downloading 5.3.7f1. (on Mac OS X 10.10.5)

>>Is there any other source of downloading support dmg's for android / ios and other platforms ?
I don't know.

>> Have they resolved it ?
I've download only "Unity Editor" from "https://unity3d.com/get-unity/download/archive?_ga=1.81714325.385895767.1414833259", and used package installer.

 

I don't know how to do it
