Are there third-party mechanical keyboards that strictly have the Apple layout? Are there third-party keyboards that have the Apple layout?

I found this question but it is not my one.

I mean, "STRICTLY", Mac layout. The sizes of keys, the paddings between keys, no Num Lock, have Fn, no numbers' area... everything is equal to the Mac keyboards, including MacBook Pro, MacBook Air and Apple Wireless Keyboard (but not the USB one).

Sorry for missing this important part. What I'm seeking are mechanical ones. I searched "mechanical keyboard Mac layout" and found the question mentioned above but failed in noticing that question was not only talking about mechanical keyboards.
If you want "clicky" mechanical keyswitches, you should look at the Matias Tactile Pro, for US$150. It is a modern version modeled on Apple's long-discontinued mechanical-keyswitch keyboard that was sold in the 1990s, the Apple Extended Keyboard, which was before the days of USB.

The keyboard layout of the current generation of MacBooks and MacBook Airs is probably not 100% identical to that of the Matias Tactile Pro, but I believe this is as close as you are going to get.

Note that you can remap any functions of Function keys in Mac OS X in software, if anything doesn't match up to your liking.



Matias also makes a Mini Tactile Pro that saves space by doing away with the numeric keypad.



Das Keyboard Model S Professional for Mac, at US$133, is also highly rated, although the key layout in the numeric keypad and certain other keys is slightly different that what Apple uses today.
