In a statement to Gizmodo, Apple publicly acknowledged the vexing display issues plaguing its latest iMac models. The symptoms of these issues, which mostly affect the 27-inch model, include yellow discoloration and screen flickering. In its statement Apple said, "We've addressed the issues that caused display flickering and yellow tint. Customers concerned that their iMac is affected should contact AppleCare." While the company has been too slow in addressing this problem, better late than never. follow link
Option-Click AirPort Menu for Network Details
If you hold down the Option key while clicking the AirPort menu in Mac OS X 10.5 Leopard, you'll see not just the names of nearby Wi-Fi networks, but additional details about the selected network. Details include the MAC address of the network, the channel used by the base station, the signal strength (a negative number; the closer to zero it is, the stronger the signal), and the transmit rate in megabits per second showing actual network throughput. If you hover the cursor over the name of a network to which you're not connected, a little yellow pop-up shows the signal strength and type of encryption.
