Apple has released Mac OS X Lion 10.7.5 Supplemental Update, an addition to the recently released Mac OS X 10.7.5 Lion that’s tiny enough not to merit its own version number. The update resolves only two issues: one that could cause Time Machine backups to take a long time to complete and another that prevented certain applications with a signed Developer ID from launching. If you hadn’t previously installed 10.7.5, you won’t need to worry about this supplemental update — the latest build of Lion 10.7.5 (11G63) includes these two fixes. (Free, 2 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.
