Dear X-Air and WeatherCat troubleshooters, . . .
This is one of five functions missing in the newest OS. Scroll a bit over half way down the article to see the details.
Sorry to see this. UNIX oldtimers will go back working with the logs as they did before OS X console, but all this seems rather silly. Console isn't for neophytes, so Apple should have made it for the power-users who understand how it works.
I can't help but suspect that this was a piece of software that was supposed to have more functionality but they ran out of time to implement the intended functionality.
Oh well, . . . . Edouard
