Problems installing unity3D 4.0.1 on Mac OSX 10.5.8 (Leopard)

Hi,

I am not able to install trial version of unity3D 4.0.1 on MAC OSX 10.5.8.

Same issue is posted here for unity3D 3.X.X version. (Problems installing on Mac OSX 10.5 (Leopard))

I am getting the installation error,
8434-unity.jpg

I have resolved the disk permission errors on my OSX. Still no luck.

Is there any compatibility issue with unity3D 4.0.1 with MAC OSX 10.5.8 ?

I can provide more information if required, about the OS.

Thanks in advance,
Purandhar K

Unity 4.x requires SnowLeopard or later.
