Quadra 630s cannot be upgraded using the current Power Macintosh Upgrade Card, despite incorrect statements on Apple's 12-Sep-94 price lists. Apple plans a PowerPC-based upgrade for the 630 series, the Performa, LC 575 and 474, and the Quadra 605. The upgrades should be available late this year. [MHA]
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.
