We all know keeping your software up-to-date is important, bug fixes come along, as well as security patches. Apple has provided a mechanism for keeping your system software up-to-date, and until now there was no quick, simple, painless way of making sure you had the latest version of all your software! Renew aims to simplify your experience, and save you time by keeping track of updates to your 3rd party software, and allowing you to download these updates just like Apples Software Update!
