Brand new iMac (though obviously it's not the hardware, it's the OS), and suddenly the App Store app refuses to launch. I've dumped a plist in preferences, but still no go. Just hangs. I'm sure others of you are having the same issue. Anyone have a solution specific to El Capitan 10.11.2? The point being, older community posts cite Apple plists that don't match what's in my own Preferences folder. Thanks!
