On the surface it doesn’t appear to be an interesting or important update, but reading the security notes it looks like this update fixes a few security holes that could allow for malicious code execution. Just check for updates from the Apple menu (or wait, you’ll get it eventually), but the Safari 5.0.2 update requires you to restart so make sure you’re ready to do than before you fire it off (like I almost did before writing this article!).
