Mac location not found for opened .dmg 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?

Tell your Mac Gatekeeper, you are the Boss and responsible for your actions and decisions.

Open the Terminal app from the /Applications/Utilities/ folder and then enter the following command syntax:

sudo spctl --master-disable


Hit return and authenticate with an admin password

That should now allow you to download and install non Apple apps, by selecting it in the System Pref > Security
