Well not that you mentioned, I was reading about the 64bit changes that OS X and Cocoa api has, and how to convert my current 32 bit app to 64 bit app. In an apple doc I read that mos of leopard app doesn't need to convert to 64 bit architecture, but later on the document its says something like, that in the future the apps should take advantage of the new 64 bit api and frameworks, or that what I understood, so, I was wondering, if Im starting a new app (small one), should I build it for a 64 bit architecture or no?, if so what should I take care of?, instead of using int use NSInteger or NSUInteger, alos instead of float use CGFloat, take care of the way I encode and decode ? I guess im missing lots, and what else should I change the build target to be 64 bit architecture?

any guidance? or should I just "let it be, let it be"

So even better, is there a convenient GUI-based way for a user to check this? I don't see anything in "About this Mac".

Actually - yes. "About this Mac" *will* tell you. If it says "G5" or "Core 2", and 10.5.*, it's a 64-bit capable Mac. If it's running any earlier OS release, a G3 or G4, or first-generation Core, it's 32- bit only.
