Mac version

Does anyone know if they are ever going to come out with a mac version for all three of the Mystery PI games? i would really like to have this on my mac but they don't have the mac version out. I found this game on my Mother-in-laws computer through something that came with her computer and I have been playing it but of course she is not to happy that I have been on her computer and not mine. I was able to play most of it on her computer but I have not been able to finish it because she keeps saying...you have your own computer go use yours. Please can someone help me and answer this, I would really like to have all three of them available to download and purchase.

Thanks
