Imac 10.8 mountain Lion up dates


Hi I would like to know when are us people going to get the date for mountain Lion .I have just brought a NEW my book live,and yes it is out of date fore us Imac people. I wish that they told us on the box that My Book Live came in. Like to know is my $300 ex drive. Can not use remote on it for our Iphone Ipad And The Imac computes that cost a lot  of money.

Hello, what type of problems are you having?
