In addition to releasing Mac OS X 10.6.3 (see "Mac OS X 10.6.3 Update Delivers Range of Fixes," 29 March 2010), Apple has incorporated that update's security fixes into Security Update 2010-002 for Mac OS X 10.5 Leopard owners. It corrects dozens of vulnerabilities related to maliciously crafted files, Web sites, and email messages, and also updates many core components (such as PHP and MySQL) to make them more robust against potential attacks. The update requires Mac OS X 10.5.8 and is available via Software Update or as a standalone download: Security Update 2010-002 (Leopard-Client) (78.39 MB) and Security Update 2010-002 (Leopard-Server) (361.4 MB).
Viewing Wi-Fi Details in Snow Leopard
In Snow Leopard, hold down the Option key before clicking the AirPort menu. Doing so reveals additional technical details including which standards, speeds, and frequencies you're using to connect, as well as what's in use by other networks. With the Option key held down and with a network already joined, the AirPort menu reveals seven pieces of information: the PHY Mode, the MAC (Media Access Control) address, the channel and band in use, the security method that's in use, the RSSI (Received Signal Strength Indication) measurement, the transmit rate, and the MCS Index. In Leopard, some, but not all, of these details are revealed by Option-clicking the AirPort menu.
