Mac desktop with MacOS High Sierra 10.13.6 will not let me get the updated version
Hello,
I have a 2011 Mac desktop with MacOS High Sierra 10.13.6 and it will not let me download any apps from the App Store or let me get the updated version (10,14,6 which is what it states that I need in order to download and use these apps). Just wondering if there is any other way I can go about getting the two apps I need which are Pages and Numbers.
Thank you in advanced.
