This text will be hiddenWhile the 2014 MBP running MacOS Catalina (10.15.5) can install and run War 3 just fine, the 2020 16" MBP, core i9 processor from this year does not allow installation from the bnet app. Manually copying files gives security issues unresolvable through settings.
Other blizzard games install just fine from the bnet app.
UPDATE 2020-07-20:
Problem is solved. The BNet app does not allow direct installation, but downloading from Games under the battle.net website does work.
Iām wondering why Reforged is the only game on the BNet app with this behavior.
