Hi- A J newbie here. I played a bit with J last year, and had to put it down to continue working on my dissertation in musicology. I'm back again, and a bit disappointed that OS X support hasn't progressed in my time away. I very much like the new Web interface, although I'll have to tinker with it to work with J on my iPad. Any Macintosh with a 64-bit CPU running Snow Leopard is a 64-bit OS. So the Mac has been 64-bit since the iPhone came out: quite a while. I'd dare say that most people with a Mac are running a 64-bit OS. By default, the kernel only runs 32-bit, but this can be changed in preferences, and the new PowerMacs are sold booting as complete 64-bit machines. But this doesn't complicate matter for 64-bit applications. Running 64-bit applications on Snow Leopard is so easy, I don't think anyone notices. If I look at my process monitor, most of my OSX application are running 64-bit, and Xcode makes it very easy to build 32/64 Universal binaries. I'd make the request that the J folks at least offer a 32/64 libj.dylib, which should take only a re-compile to produce, considering J already runs 64-bit on Linux. I had suggested this a year ago, but guess no one noticed.
