Diablo 3 will not install due to mac os Catalina newest update as of july 13 2020 is there a fix out there yet?
Hey TimidComic9,
It’s possible that the version on the CD is so old that newer OSs don’t think they can handle it.
But, if you enter the CD key into your Battlenet account, it will permenently unlock the digital download which is always maintained at the most recent version.
You can enter the key on your Account Summary page.
