Hello Doug,
The files that you've downloaded are in *****.ast format (=custom-files). They are not zipped. After downloading and copied on a disc you can load them into the CUSTOM of the KN7 (Doug, please use: custom style load/save in the disk-menu)
I hope this information will help you?
I'm sorry I can't help you with the Mac, my knowledge is not good enough for that. Pherhaps someone else could help you if the Mac give problems with this.
Best greetings,
Cees
