Introducing Refinery Refinery Today we released our first app, Refinery. Refinery is a system utility for customizing the appearance and behaviors of your Mac. You can change what the Dock looks like, change icons for the Finder, and change various hidden options in the system. We are releasing Refinery as donationware, so use it as much as you want for free, but if you like the app, please consider donating. As this is the first public release of Refinery, we need your feedback, so please email us at Thanks a lot!
