Along with OS X 10.9.2 (see “10.9.2 Fixes Critical SSL Security Bug, Adds FaceTime Audio,” 25 February 2014), Apple has released Security Update 2014-001 with security fixes for those still using OS X 10.8 Mountain Lion, 10.7 Lion, and 10.7 Lion Server. Alas, it seems that people running 10.6 Snow Leopard are now out in the cold, since this is the first security update to drop Snow Leopard-specific fixes. Security Update 2014-001 doesn’t need to address the recently discovered SSL/TLS security vulnerability (see “Apple Updates iOS and Apple TV to Fix Critical SSL Security Bug,” 24 February 2014) because it doesn’t affect versions of Mac OS X prior to 10.9. But the fixes it provides are still significant, addressing vulnerabilities in app sandboxing, font handling, image display, Nvidia drivers, Quick Look, QuickTime, and the system clock, along with the Apache Web server and PHP scripting language. (All updates are free. For 10.8 Mountain Lion, 115.8 MB; for 10.7 Lion, 123.4 MB; for 10.7 Lion Server, 173.6 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.

Not being able to upgrade with the Security Upgrade concerns me, but I don't want an OS that overwhelms my CPU.
