Security Update 2005-002 Fixes Java -- Apple has released Security Update 2005-002 to eliminate a vulnerability through which an untrusted Java applet could gain increased privileges and potentially execute arbitrary code. The fix applies only to Java 1.4.2 (and thus Mac OS X 10.3.4 or later); previous Java releases are not affected. The update is available via Software Update and as a separate 16.4 MB download. [ACE]
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.
