So I bought this keyboard. Armaggeddon Black Hornet MKA-3 mechanical gaming keyboard. Here's the link to it.

They provide Windows drivers so my it works nice on my PC. I use both Linux and Mac OS at my workplace, it works great with my Linux without any configuration but surprisingly not functioning well with my Mac. Although I don't use mac very, I still want to be able to use my keyboard when I have to use Mac sometimes.

Here's what happened, I plugged in the USB, reboot to Mac, can't type password at the login screen, I plugged in my apple keyboard, and logged in. The system detected my new keyboard, asked me to press the key right to the left shift key, after I pressed it for several times, it says the keyboard is not recognised and I have to choose one manually.

So I chose US standard layout, but the key mappings are all messed up. I mean you have 8 when you type 1, and you see 's' when you press space.

All my other keyboards are working fine, I want to ask is there anyway in mac you can manually 'program' the key mappings, or what should I do to make it work.

Here's some a list of wrong key mappings.

1 = 8
2 = 9
3 = 0
4 = 'Enter'
5 = 'Not Sure'
6 = 'Back space'
'Backspace' = \
' = q
, = 4
. = n
p = f
a = d
i = b

Thanks for any help.

Perhaps Ukelele is what you're looking for? It's a nice front-end to make custom keyboard layouts for Mac.

Also the solution listed here at SO might be helpful if it's more of a problem with the non-letter keys.

I also have same keyboard and I know how painful it is to make it work in OS X. I am using Karabiner and created a custom keyboard mapping here:

I am using it now and so far it is working fine except the Tab key which fires the same keycode with Backspace key. I prefer to keep backspace key as it is, and remap Caps Lock key to be the Tab key.

I hope it's helpful.
