Before updating to mountain lion
If you have an Apple Pay-compatible i Phone or Apple Watch, you can now use it with your Mac to complete online Apple Pay transactions.Optimized Storage Apple’s penchant for Solid State Drives – SSDs – in most Macs mean faster storage but far less of it than before, which means it’s easier to run out of space as you put more apps and data on your Mac.
Changes to i Cloud Drive in Sierra include the ability to automatically sync the contents of both your Mac’s Desktop and its Documents folder, the two locations most of us keep most of our files.If your system is running on “Lion” (last year’s big Mac update), just open the Mac menu in the top-left corner of the screen, select About This Mac, and click the More Info button.When you do, the next window will tell you the model and date for your particular Mac.Now Sierra can automatically move infrequently-used files to i Cloud instead, freeing up space on your Mac’s drive.You can still find the file right where you left it.But if your Mac chokes during the Mountain Lion update and refuses to boot up again, you’ll be happy you made the effort.
The good news is that the Mac comes with a built-in, easy-to-use utility called Time Machine.
Now you can use Siri on the Mac to schedule appointments, play music, set up reminders, find files and do lots more.
Universal Clipboard This new feature lets you copy on one device and paste on another.
All you need is an external hard drive (which you can snag online for about $100 or so) and a little patience.
Once you have Time Machine all set up, it will back up your Mac once an hour whenever the external drive is connected to your system.
If you have problems with the Mountain Lion update process—or, indeed, if anything bad befalls your Mac—you can use your Time Machine backup to restore your system, either to your old Mac or a brand-new one.
