Hi, I'm trying to install numbers and pages to a fresh installation of El Capitan on a macbook late 2008. When I go to the App Store, it tells me that Sierra is required in order to install. I tried the install iWork 09 trial then update route, but I'm not able to open any of the app as trials after installation and the App Store doesn't show any update available. I also tried to install a cracked version of iWork 09 with the same result. Anyone has a solution? Thanks in advance.
