just recently migrated complete to 7 to a 2015 Mac Pro from an older one.. all K7 products say repair in NA window.. how exactly do I download 15 standard upgrade in this situation, or does it even matter?
It does not matter, to install K15 you do not need to install K7. The only thing is that K7 may have (and most probably has) content and plugins that K15 does not have.
But you may install and use at least some of them later.
Thanks, appreciate it!!
