15 or 19 F-keys? Really?
The Mac numpad layout is completely non-standard and you're going to have a VERY hard time trying to find something the same in a mechanical board or USB numpad.
There is the Logitech G710+. Full backlighting, 12 function keys + 6 macro keys. Cherry MX brown switches with orings preinstalled. I have heard that it doesn't feel as "solid" as a Ducky or other good plate-mounted board, but AFAIK none of the "good" board brands have extra function keys or macro keys. The Corsair K90 is another option (MX reds on normal keys), but the macro and function keys are rubber domes.
Honestly, though, I'd just buy a Ducky Shine. Cherry MX switches throughout, plate mounted, solid feeling, full backlight, standard keycap sets fit (this can be a big issue, some boards have non-standard space bars, etc), etc. Go with the TKL if you can live without a numpad, otherwise full size.
