So I am trying to download Ruby from this site — http://railsinstaller.org/en.
Managed to download Mac OSX 10.7 and 10.8 , but when I tried to open it, this is the message I got :
“RailsInstaller-1.0.4-osx-10.7” can’t be opened because it is from an unidentified developer.
Your security preferences allow installation of only apps from the Mac App Store and identified developers.
Safari downloaded this file today at 10:34 pm
Any idea how to fix this ?
