Wi-Fi Diagnostics app not found After reading this CNet article I was pretty excited to have a tool that monitors my wireless network since I'm in the process of setting it up well.

Wi-fi Diagnostics is said to be in the CoreServices folder (see the CNET article) and so I fired up terminal and got this back:

$ /System/Library/CoreServices/Wi-Fi\ Diagnostics.app
-bash: /System/Library/CoreServices/Wi-Fi Diagnostics.app: No such file or directory


Any ideas where my Wi-Fi Diagnostics.app  has gone off to? I'm runnning OS X 10.8.4 on MacBook Air 5,2.
In 10.8.3 and lower, the program Wi-Fi Diagnostics is the tool to measure RSSI, signal to noise ratio and to scan for hot spots (a.k.a. war driving). That app is gone on 10.8.4 and is replaced by Wireless Diagnostics that has many but not all the same functions. Bonjour scan is out for instance, but the scanning and measuring tools are far better in the new tool. 

The new application Wireless Diagnostics.app works mostly as the referenced article notes as well


  it is now more conveniently available by holding the Option key, clicking the Wi-Fi menu, and selecting Open Wi-Fi Diagnostics.


PS: As a side mark, you can't execute Cocoa applications from bash the way you tried. Use /System/Library/CoreServices/Wireless\ Diagnostics.app/Contents/MacOS/Wireless\ Diagnostics or open -a "Wireless Diagnostics instead.
