I will ask you here, again,
Why do you need Mavericks so badly? What is in Mavericks that you absolutely must have?
What software are you running or need the requires OS X 10.9 Mavericks as the minimum OS X requirement?
The minimum OS X requirements for most of the software on the Mac App Store is either 10.6 or 10.7'and above.
What is so special to you about OS X 10.9 Mavericks that you need it so badly?
And, It you needed OS X 10.9 Mavericks so badly, why didn't you install and download this version when it was available and free over a year, ago?
OR are you just coming to these forums just to rant and rave for no real reason...
OS X 10.8 Mountain Lion is much better than 10.7 Lion. It is what Lion should have been,
Are you ranting just because you can't have something any longer because it is no longer available to you?
OS X Mountain Lion is not that much different from OS X Mavericks.
OS X Mavericks, I feel, has more iOS-like junk in it (some of it I never use) than the previous OS X 10.8 Mountain Lion.
