Console.app bounces but does not start In a (possibly related) recent question I outline some background to a decidedly unhealthy Mac Book Pro (patched up to date with the latest 10.6 updates). 

A suggestion was to try to see what clues might appear in Console.app ... but Console.app doesn't start. It bounces in the dock, then reports that it can't open. 

Where can I find the logs that Console.app reflects?
Logs from Console.app are in 3 different places:

/var/log (which is actually /private/var/log)
~/Library/Logs (~ means your home directory)
And /Library/Logs

When looking for general errors, one of those locations should provide insight. Note that Console.app also shows Crash logs, and specifically lists some special log files that may not be in one of the above three directories. However, those are special purpose and won't necessarily provide any insight into the issue at hand.
