chelleeee

hi guys, i have researched the internet front to back and i cannot find ANYTHING to help. So recentley i updated my mac and everything was fine, so i decided to play some modpacks on technic so i opened it and it said "you cannot open this file because it is an unidentified user" so i deleted it, i went into security and allowed it. i downloaded a new one and i opened it and it said "Safari can’t open the file “TechnicLauncher-5.jar” because no available application can open it." and there is really no application for it. It'll say "This is a download from the internet, would you like to open it" so pressed yes, it did nothing i pressed it again and it said the same thing "Safari can’t open the file “TechnicLauncher-5.jar” because no available application can open it." So i do not know what to do and i really love all the mod packs. SOMEBODY HELP! -chelleeee (yeah so i kinda realized no one would see this at 2:44 am, so i wanted to send it again, 24 ppl have seen my other one....but no replies. so here it is again.)
