About
Currently, Chromium does not use Sparkle or any other mechanism to auto-update itself. To the developer this is not a bad thing, but for those focused on using and bandaging the bleeding edge in browsing, auto-updates are a very nice feature.
Chromium Updater.app consists of just a small shell script wrapped in an Automator application. It doesn't make Chromium auto-update itself, but it sure makes the process a lot easier. Just quit Chromium if it's currently running, double-click Chromium Updater.app, and then resume doing whatever you were doing before opening it. Chromium Updater will let you know when it has finished updating Chromium.app.
Chromium Updater downloads the current binary snapshot of Chromium.app to your “Applications” folder. If a version currently exists there, it will be overwritten.
Contributions
Chromium Updater is a modified version of a few scripts I found online. The source is included included in the readme. (You can also open the workflow inside the app in a text editor to veiw it.) If you feel you can make it better, by all means, please e-mail me at with your suggestion.
