\"\"If you\u2019ve installed OS X 10.8 Mountain Lion already, you may have run into one of the new additions to the OS by the name of Gatekeeper. Like other famous gatekeepers<\/a>, this one only lets certain elements through. In this case, any applications being launched need to fit certain criteria in order to launch.<\/p>\n

It\u2019s a great idea in theory – you\u2019re only launching applications you know are safe, reducing the proliferation of malware. Gatekeeper requires that the application either be \u201csigned\u201d by the developer or that it was downloaded from the Mac App Store (which, in many cases, means that it\u2019s \u201csigned\u201d anyway) in order to be deemed okay. With more recent software, this isn\u2019t much of a problem; developers have known about this for a while and it usually just means updating to the latest version.<\/p>\n

Unfortunately, older applications that are still useful but for which upgrading may be prohibitively expensive or inconvenient (such as Adobe Creative Suite or Final Cut Studio 4) don\u2019t necessarily have this identifier. To Gatekeeper, there\u2019s no difference between Photoshop CS5.5 and malware – they’re both \u201cunsigned\u201d programs, and it won’t let you run them.<\/p>\n

To get around this, you can simply right-click the application and select “Open” to launch it. That fixes the issue on a program-by-program basis while keeping Gatekeeper on at all times.\u00a0In very rare<\/em> occasions, you may temporarily need to turn off Gatekeeper, launch the app so that the system knows it’s okay, then turn Gatekeeper back on. Lloyd Chambers at MacPerformanceGuide has put together a short tutorial<\/a>\u00a0showing you how to do this.<\/p>\n

If Mountain Lion isn\u2019t letting you launch your favorite program, this may just be ticket you need.<\/p>\n","protected":false},"excerpt":{"rendered":"
