Bad Power Mac G4 Hard Drives -- Apple has revealed that some Power Mac G4s (Digital Audio - those released in January of 2001) contain defective 40 GB and 60 GB hard drives that can damage files, cause data loss, and potentially prevent the computer from starting up. Only a limited number of machines sold in the U.S. and Canada are affected, so if you have a Power Mac G4 (Digital Audio) with a 40 GB or 60 GB hard drive, read the Tech Info Library's instructions on how to determine whether your Mac has a bad drive. If so, Apple will replace the drive under warranty. [ACE]
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.
