OSX i386/x86 and x86_64 - time to switch supported platforms?

[Pavel Perikov]

To make it clear. Leopard (released October 2007) fully supports x86_64 executables. Given upgrade rate of Mac community I think it's pretty safe to state that majority of mac owners have x86-64 capable systems.

I'd venture a guess that far more people are interested in running 64-bit GHC on OSX than in running GHC on what is now fairly antiquated hardware.
