Does it make sense to support 32 bit OSX?

I'm wondering, from a practical standpoint: does it make sense for me to put effort into support 32 bit OSX?  My 64 bit version works great, and from what I understand all new Macs are 64 bit.

Any feedback would be most welcome!

It depends what you're building.. If it's an app, then you're probably fine just doing 64-bit. But if it's a plugin, many hosts will be running in 32-bit mode to stay compatible with older plugins, so you'd want to make yours a universal binary.

Thanks, that's useful to know.

As it happens I was able to get 32bit working easily enough...
