I am desperately trying to get my MacBook Air to allow me to use a brand new external hard drive (thus the title My Passport Problem). When I try to open the installer JPNLanguagePack Installer.pkg I get the following message: JPNLanguagePack Installer.pkg can't be opened because it is from an unidentified developer. Your security preferences allow installation of only apps from Mac App Store and identified developers. I don't know what to do as this is the the link that comes up with the My Passport. I'm not real tech savvy so I am just lost as to what to do. Can somebody please tell me what to do? I joined Mac Rumors through facebook so I'm not sure what email address your responses will go to. Please send responses to firstname.lastname@example.org Thanks.
