Back in February, Apple's Worldwide Developer Certificate, designed to
verify third-party apps and services, expired, requiring Apple to
issue a new certificate for developers to use. OS X installation files
downloaded from the Mac App Store before February 14, 2016 and stored
on a computer or USB drive are no longer functional. This includes
installation files for OS X El Capitan and older versions of OS X like
Mavericks and Mountain Lion. Users who keep OS X installers on hand or
have created USB install disks in case of emergencies should replace
their files with new versions by re-downloading them through the Mac
App Store using purchased history.
Users who can't replace an expired certificate can still use older
installers by changing the dates on their machines.
In the OS X Installer, choose Utilities > Terminal.
date 0201010116 and press Return.
Quit Terminal and continue the install.
OS X Installers Downloaded Prior to February 14 No Longer Work After Certificate Update
