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.

 
 

SuperClock! error

Send Article to a Friend

SuperClock! error -- Steve Christensen, the author of SuperClock!, writes in regard to Mark H. Anbinder's article "Quadra Vampires", "Well, that's news to me. SuperClock! was written completely in assembly language, so there aren't any compiler-oriented issues to deal with. SuperClock! also doesn't do any cache-oriented operations directly - I make no hardware assumptions of that type since I want to be able to run on 68000s as well as 68040s. It's possible that some of the system code I call may flush the cache as part of its operation, though. I work with the software guys that did the ROMs for both Quadras, both use SuperClock! on their Quadras, and I haven't heard any complaints."

[Adam: Our apologies, Steve. Mark said that the information came from someone within Apple, so it's more curious that you weren't contacted first. Though SuperClock! is off the hook as a Quadra vampire, I would warn people to generally be aware of older programs that might exhibit this behavior. We don't know of any specifically, but older compilers had no way of knowing about the Quadras and certain out-of-date code may run slowly on them.]
