Hello
recently I hooked up a keyboard to my mackbook pro to play games
it recognizes it as a generic

the problem is while playing games using FPS controls, like WoW (W,A,S,D)
pressing a second key, cancels the first one

say I'm holding down the walk button, if i tap the turn right button, the character stops walking

Is this a problem with my USB to PS/2 converter?
or problem with the MAC?

It may be specific to your particular keyboard. One of the things to look for in a gaming keyboard is "n-key rollover." The keyboard may be limited in how many simultaneous keypresses it can track. A keyboard with true n-key rollover (like my CVT Avant Prime) can keep track of every individual key, up to all 100+. Usually, a 4-key or higher rollover works well enough, but a 3-key rollover is not enough for some games.

It's almost certainly because you have a cheapy PS2 keyboard connected over USB, not because you're using a Mac (MAC is short for Mac Ain't Capitalized, btw). As JAE said, be specific about the model of keyboard - and while you're at it, be specific about the model of USB adapter.

the keyboard works fine on my PC
The keyboard is an HP multimedia internet keyboard 5187
something like this http://www.geeks.com/details.asp?invtid=5187-1767&cat=KYB&cpc=DSP

here is the converter

well you can see if there's a problem with the Mac or with the converter two ways:

Use the converter to connect teh keyboard to your PC
Use the built-in keyboard on your Macbook Pro

I wouldn't be surprised if both of the above work fine; OS X doesn't have support for PS2 devices, so I wouldn't be surprised if a PS2->USB adapter didn't work so hotly either.
