As I noted in Part 1 of How-To: Decode Apple’s Tech Specs pages before buying a new Mac, Apple has designed the Mac purchasing process to be easy: pick a model, pick the good, better, or best configuration, hand over your cash, and enjoy your computer. Since most people get confused by tech specs — bullet points filled with numbers and acronyms — Apple downplays them in its marketing materials, leaving customers to sort through the details and figure out what most of them mean.

But these specs are really important when you’re shopping for the right Mac for your current and future needs. So I’ve created this How-To guide to walk you through each of Apple’s Tech Specs pages using clear explanations, hopefully enabling you to properly understand what you’re about to buy. Part 1 focused on the “big 5″ Mac specs you really need to know about, and this Part 2 looks at the rest — generally things that remain the same in a given model, regardless of the configuration you choose…

A new Wi-Fi scanner tool is in Mountain Lion’s refreshed Wi-Fi Diagnostics Utility, allowing users to easily discover Wi-Fi networks within range and view related data not available from Apple’s Wi-Fi menu bar item. Comparable to third-party Wi-Fi stumbler tool iStumbler, the scan tool provides data for BSSID, band, protocol, channel, signal strength, security, and more. It also has Active and Passive scan modes.

From the window, you can see what networks are in your area and their strength. Some maneuvering of base stations can increase coverage to the outermost areas of your house, and it is much, much easier to see slight differences in numerical signal vs. noise strength over those four waves Apple uses in its Wi-Fi menu.

Additionally, by looking at what Channel (1-13) your base station is on, compared to your neighbors (or other base stations in your house), you can often find the least used channel in your area to improve reception.

If you are interested in using the new Wi-Fi scanner tool, OSX Daily provided the necessary steps for quick access:
