Error when launching apps
Hi,
Recently, I've had a problem with any app from the App Store on my computer (iMac). When I launch it, it takes some time to "verify" the app and then asks for my apple ID and password. After I type it in, an error message pops up sayng "Couldn't verify this computer. Contact the Apple support." I'm running OS X 10.11.3 on an iMac form 2015.
iMac, OS X El Capitan (10.11.3)
