IcyOverSquirrel

when I try to open the technic launcher I get this message"Apple could not verify “TechnicLauncher.jar” is free of malware that may harm your Mac or compromise your privacy" I haven't had this problem before but I just had to redownload the launcher and now I get this message. I do have java 8 which seems to be most people's problem and I have the jre-8u451-macosx-x64.dmg
