With Mountain Lion’s quiet announcement came a lot of questions about compatibility and price. While we don’t know exactly how Apple plans to charge for Mountain Lion just yet, we are starting to hear that Mountain Lion will be dropping support for some older Macs.

I’m sure there will be a couple of people annoyed by the move, but to be honest, the minimum required specs seem to be pretty fair. We should note, however, that minimum spec requirements do not necessarily ensure that the operating system will be running in tip top shape. My MacBook Pro is a 2009 edition, running Lion. Lion works quite admirably, but I did notice some drastic differences in responsiveness after my move from Snow Leopard to Lion. We expect the same thing to happen with Mountain Lion. Heck, we should expect it to happen with any computer running a new operating system unless it was purchased the same day
Snow Lion Mountain Lion comes out. If you’re adamant about running the latest OS, now’s the moment to upgrade.
