I'd like to make backup of some specific console logs.
How do I find the location of a specific Console log file on my Mac to copy as back up?
Console.app's logs are stored in the following locations:
/var/log /Library/Logs ~/Library/Logs
To back up all the logs, simply copy the contents of these three folders to another location.
To back up a single log, look in Console.app for the log that you want to back up, select it in the sidebar, then press ⌘R (or right-click and select Reveal in Finder). This file can then be copied to another location.
