MacUpdater is published by www.corecode.io and is very useful for keeping application updated.  The Apple App Store is useful for updating only the apps that were purchased there. However, most Mac users still have dozens of programs that they have found elsewhere and we want them updated too.

MacUpdater is an inexpensive utility that can run in the background or as a stand alone application. I feel it is very generously priced without having a monthly subscription fee!
