Apple recently seeded the “Golden Master” release of its Mountain Lion operating system to developers. The term “golden master,” by the way, is taken from audio recording where it refers to a single copy of either the original, recorded audio or of a finished album from which all other copies are made. In software, the golden master is the final, canonical version to be released to the public. All that means that Apple is very close to releasing Mountain Lion which will be available in the Mac App Store for $19.99. If you’re planning to upgrade, here are a few things you can do to get ready.
Backup
It’s always crucial to make a backup of your data. Lots of things can go wrong during a software upgrade or just in daily life: the power could go out, your download could be corrupt, or you might accidentally erase your hard drive (hey, it happens). A good backup should be up to date, verified (you’ve tested to make sure you can recover your data from it), and on a separate hard drive. Preferably you’ll also have a copy of your most important data in a separate location (referred to as an off-site backup). That way your data will be safe even if something terrible happens to your house. And just to be clear, having a backup means you have two copies of everything, one on your computer and one on your backup drive. Backing up your photos and then deleting them off your laptop to save space doesn’t count.
On this one point, I will allow myself to get preachy. Backup, backup, backup because, as the saying goes, there’s no use crying over spilled milk. Unless it lands on your laptop.


If you’re like me, then you loathe the idea of getting your computer fixed by a professional. If you’re like me, you picture “computer help” as a long, involved, and inconvenient process, during which you either haul your PC up to the local computer fix-it store and wait for hours, or ask some unknown computer-fixer into your house and again, wait for hours.
If you use a computer and the internet at the office or at home, you might need to share the service with others. If your service is currently set up for only one person, you will be thinking about what to do to change that. How do you go about setting up a computer and internet system for multiple users? The answer: an Ethernet router.
