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.

 
 

Security Update 7-12-02 Fixes Software Update

Send Article to a Friend

Security Update 7-12-02 Fixes Software Update -- Apple has released Security Update 7-12-02 to fix a recently reported problem with Mac OS X's Software Update utility. Software Update 1.4.6 eliminates concern over an attacker setting up a machine to masquerade as the Software Update server swscan.apple.com and deliver malicious programs in the guise of legitimate updates. Although Software Update 1.4.6 still relies on the same server, Apple is now cryptographically signing all downloads, and Software Update installs only downloads that Apple has signed, a capability that has been available in the Mac OS 9 version of Software Update for some time. Downloads that lack a valid signature are deleted. The 2.3 MB Security Update 7-12-02 is available via Software Update itself or as a separate 844K download. [ACE]
