To my knowledge, there are no Cocoa-specific problems in VTK in 64 bit. 
However, VTK has problems with 64 bit on any platform.  There are many
many many places where it uses 'int' interchangeably with 'size_t'
types.  Those types are not necessarily the same size.

Just look at this Vista 64 bit dashboard:

That being said, almost all tests actually pass in 64 bit, so it's
pretty usable in practice, at least with small datasets.

I know nothing about X11...
