I tried downloading
android-studio-ide-181.5056338-mac.dmg to install it, but double clicking the .dmg does not nothing but put
Android Studio 3.2.1 under the locations sidebar in the Finder. When I click that, I get the error message:
I tried doing the same for installing
Amazon Photos and the exact same thing happened.
What's going on with my Mac being unable to open .dmg files?
Mac OS 10.14.1 (18B75)
