While one does not begrudge Apple their current mass market success one can sometimes long for the good old days when they only managed to sell computers to discerning sensible people.
Well done Johnny433! You managed to download and install Mountain Lion that’s five stars from me right there but then…
Oh dear! Was there some part of the App Store’s description of Mountain Lion that you did not understand?
To clarify: the latest Macs come with the latest Intel processor known as [wikipop]Sandy Bridge[/wikipop] which was launched in 2011 and features [wikipop search=”Intel Quick Sync Video”]Quick Sync[/wikipop] that can pump video (encoding and decoding) without troubling the main part of the CPU. So if you do not have the latest Macs with the latest processors you will not be able to use Mountain Lion’s AirPlay Mirroring (note: “AirPlay Mirroring requires a second-generation Apple TV or later, and is supported on the following Mac models: iMac (Mid 2011 or newer), Mac mini (Mid 2011 or newer), MacBook Air (Mid 2011 or newer), and MacBook Pro (Early 2011 or newer).”) you can set up some other form of mirroring (there are numerous options depending on your particular needs) that will be passed through the CPU.
Copies of this piece can be saved on to a floppy disc and mailed to you via the postal service if you feel that the march of technological progress is passing by too rapidly.
