After the installer disappears than Choose the Executable to start the program, "RootsMagic.exe"
If Roots magic doesn't start, duplicate the RootsMagic.app wrapper file, delete the old one. Note: If you rename the copy of the old one, it will cease to function, then you will have to duplicate it again
Finally add winetricks! This will make it work when you try to add facts to existing people, otherwise without it you can pretty much only view things. To get to winetricks two-finger click or right-click the RootsMagic copy.app and click on "Show package contents"
