Coming on the heels of its latest revision of the 13-inch MacBook, Apple has released updates for Mid-2010 MacBook users working with either the 32-bit or 64-bit version of Windows in Boot Camp. The updates address a spurious warning message that can appear when clicking the brightness tab in the Boot Camp Control Panel, and fix a bug that could silence headphone audio. Installation instructions are available on Apple's Web site. (Free, 1.5 MB)
Option-Click AirPort Menu for Network Details
If you hold down the Option key while clicking the AirPort menu in Mac OS X 10.5 Leopard, you'll see not just the names of nearby Wi-Fi networks, but additional details about the selected network. Details include the MAC address of the network, the channel used by the base station, the signal strength (a negative number; the closer to zero it is, the stronger the signal), and the transmit rate in megabits per second showing actual network throughput. If you hover the cursor over the name of a network to which you're not connected, a little yellow pop-up shows the signal strength and type of encryption.
