Bitmask requires Mountain Lion or newer.
Optionally, you can authenticate the signature for the Bitmask .dmg file using this signature file.
Once the file `Bitmask-OSX-latest.dmg` has been saved to your computer, mount the `.dmg` image and drag the `Bitmask` icon to your `Applications` folder.
You can browse all releases for old or experimental downloads.
You should install the latest stable release. Downloads tagged with “RC” are “Release Candidates” and receive frequent experimental updates that may break the application.
