Sparkle 1.5 is a free Mac developer toolkit that enables you to build in an auto-update facility within your Mac apps, so the end user can see if a new version is available, read the release notes and choose to install now, later or not at all. It's a free development toolkit, so there's no reason why you shouldn't give users this option.
