*Mac OS X Note: Depending on your system settings, the system might warn you that "Jaxx can't be opened because it comes from an unidentified developer." You can either change your system settings to allow apps from unknown developers in your "Security & Privacy" settings, or simply right click Jaxx → Open (as administrator), which will prompt you with a warning.
