Apple has released two Java SE 6 updates that deal with recent vulnerabilities identified by Oracle. The Java for OS X 2012-005 update for OS X 10.8 Mountain Lion and 10.7 Lion deactivates the Java plug-in when no apps have run for an extended period of time. If the previous Java update for Lion wasn’t installed (2012-004), this update disables the Java plug-in immediately. The Java for Mac OS X 10.6 Update 10 for 10.6 Snow Leopard similarly configures Web browsers to not automatically run Java and deactivates after no app activity for an extended time. Both updates from Apple bring Java up to version 1.6.0_35, and you can re-enable Java in both by clicking the region labeled “Inactive plug-in” on a Web page. The updates are available via Software Update and direct download, and Apple reminds you to quit any Web browsers and Java applications before installing either one. (Free, 67.2 MB and 81.9 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.
