I know that Unity on Windows can access ~3.5GB of Ram, because it’s a 32bit application and ~500MB of address space is reserved for other parts of the system, but we’re having some huge problems with Unity’s memory management and I’m wondering whether the situation is different on Leopard or whatever the latest version of MacOS is now. I see Macs with 8GB of RAM, but can Unity use all of it? Or is it limited to ~3.5GB as it is on Windows?
Unity is a 32-bit app on OS X, so the limit is 4GB for Unity. Other apps can still use whatever RAM is left over, if you have more than 4GB.

Thanks for the quick reply. I was hoping for a different answer, obviously, but I was fairly certain that this would be the case.
