Locate a log file using Console on Mac
You can use Console to find out where a log file is located on your computer.
Note: If you’re not logged in as an administrator, you need to enter an administrator name and password to search for and view log messages.
In the Console app on your Mac, select Log Reports in the sidebar.
If the Log Reports category isn’t visible, click the Sidebar button .
Select the file you want to locate, then choose File > Reveal in Finder.
A Finder window appears with the log file selected. If you don’t have read permissions for the folder containing the log file, you may be restricted from viewing the log file directly in the Finder.
