At iMore, Rene Ritchie looks at the fusillades being thrown at Apple so far in 2013 — endless nonsensical punditry, rumors of iPhone production cutbacks, possible stock price manipulation — and how everyone is attacking the supposedly invincible market leader. He argues that Apple is fighting against psychology as much as competing products, and points out the company’s edge. Ritchie writes: “But here’s the thing — Apple has been here before. They’ve been to the very bottom, and they came back. Apple knows they’re beatable — that everyone is beatable — and they know how to fight their way back. It’s part of them now.” follow link
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.
