Apple’s new version of OSX is due this month (the gold master pushed to developers this week, release to the public usually follows two weeks later). One catch, older Macs that can run Lion will not be able to run the new OS. My MacBook is barely under the wire and will get Mountain Lion, but this is probably the last OS update for this particular piece of hardware.
To see if your Mac will run Mountain Lion, click the Apple logo in the top left, go to “About this Mac”, and select “more info”. You will see the model name for your Mac (mine is Late 2009 MacBook).
Here is the list from Apple of Macs that will run Mountain Lion:
- iMac (Mid 2007 or newer)
- MacBook (Late 2008 Aluminum, or Early 2009 or newer)
- MacBook Pro (Mid/Late 2007 or newer)
- MacBook Air (Late 2008 or newer)
- Mac mini (Early 2009 or newer)
- Mac Pro (Early 2008 or newer)
- Xserve (Early 2009)
If your model is not listed, you’re stuck with your current OS (you may be able to upgrade to Lion, but personally, I wouldn’t recommend it). Even if your model is listed, some features of the new OS, such as Power Nap and AirPlay, may not be supported on your Mac. Review the tech specs on Apple’s site to review which features your hardware supports.
The same thing is happening in iOS 6, due this fall. First generation iPads cannot run iOS 6, and only the latest generation iPads will support Siri.
