Let me try and elaborate down a few different roads. I have had this problem too, on a Mac. Double clicking doesn't work, ever. If you Right-click, then there should be a menu that pops up. Click 'Open'. Then you will be allowed to override the preferences for that file. Apple trying to keep you safe, but it shouldn't harm your machine. That will allow you to install forge for the regular launcher. However, if you use [MultiMC], (which is basically designed for Mac, I think the author uses one), then it installs forge using a fairly easy to use Gui. Just follow installation instructions. It allows you to set up your own instances and play them with a lot more control than technic, and If I must say, works better than the Vanilla Launcher. It is the only Minecraft I have on this computer. :P If you have any questions, I would be glad to be of assistance.
