Apple has released iPhoto 9.4.1 to improve synchronization of photos with iOS devices via iTunes and fix a problem with downloading and viewing photos synced from Facebook albums. The update also fixes two specific crashes: one when using the Export command and another when upgrading multiple books, cards, and calendars. Note that iPhoto 9.4.1 now requires OS X Mountain Lion 10.8.2 or Lion 10.7.5.

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.
