So recently I bought a used iMac Late 2009 for my main computer, mainly because it has 12GB of RAM and 3TB of HDD, but I liked that it came with not only a wireless keyboard but also came with a wired aluminum keyboard with numeric pad. There is only ONE problem I found when I found it in the box: it has two missing buttons. The A and the - on the numeric pad. Yes they are functional, the plastic button itself is missing. I do not want to throw this keyboard away and I don't want to send it back to the seller, so do you know where I can buy the missing buttons?
