Installing Unity on iMac

Hello.

I have been using Unity 3.3 on Windows for a month in readiness for a commercial iOS project.

I have now downloaded what is labeled on the Unity website as “Free Full Version for OS X with Unity Pro, Android and iOS trials.”.

However I installed it on my iMac but it seems all I can have is a 30-day trial and it requires activation.

Is this normal? Is there actually an unlimited free version as there is on Windows?

I should add that I have emailed support but “We aim to respond to questions within five working days”.

After the 30 day trial, it turns into the free version.

Ah, thank you!
