Works great, well worth the money

Ever since the latest OS update my mac has been sloooowwww, RAM basically pinned as soon as I do so much as launch a browser. And in this new OS update they got rid of the "purge" command for freeing up RAM. This app takes care of it for you, and can be set to do it automatically as soon as the available RAM drops below a certain point. Sometimes freezes up the computer for a few seconds while it does its thing, but never crashes it. Easily worth ths small price they ask for the app.
