Posted July 22, 20178 yr I am trying to use Forge for the first time to download mods for Minecraft. I download Forge, and then when I try to open it, a message pops up saying: “forge-(numbers)installer.jar” can’t be opened because it is from an unidentified developer. Your security preferences allow installation of only apps from the App Store and identified developers. What do I do? Here is a Picture of what happened when I tried to open to thing that I downloaded. Please Help.
