So, the keyboard works but only partially, the at sign is not the right place, certain function keys do not work etc.
This is the same keyboard as my 2011 iMac.
I use this keyboard with my Mac mini PowerPC.
The reference is received MB110F / B then it should have been the model "A".
First time I'm disappointed Amazon ...
In short, do not buy this keyboard if you're running Snow Leopard 10.6.8 or higher.
Personally, I still think keeping the keyboard. I have 30 days to decide me, but since he works for the use I have with the mini.
Anyway, it's a shame I did not get the right keyboard.
