Is there any way of Filtering out messages from OS X system log?

Is there any way of Filtering out messages from OS X system log?

I am looking through the log on an old MacBook running Lion.

This has an error message every 10 seconds from an obsolete service:

com.apple.launchd.peruser.503[154] (de.novamedia.VodafoneDeviceObserver[1386]): posix_spawn("/Library/Application Support/Vodafone/NML2NDeviceObserver.app/Contents/MacOS/NML2NDeviceObserver", ...): No such file or directory

The actual app is long gone, it was only the launch service that is generating error messages (for the last 5 years!)

if you just wish to hide the error messages that are cluttering up the console log, for easier readability, then this can easily be accomplished by selecting any one of the offending event messages, then click 'Ignore Sender' on the Console toolbar; those messages will then be hidden from view. the event messages are still generated, until you fix the obsolete driver issue, but you won't see them in the Console. see more info HERE and HERE.

have you tried to locate & remove the obsolete Vodafone driver from the LaunchAgents, LaunchDaemons and/or StartupItems folders?

have a look in these locations:

1. ~/Library/LaunchAgents
2. /Library/LaunchAgents
3. /Library/LaunchDaemons
4. /System/Libary/LaunchAgents
5. /System/Libary/LaunchDaemons
