We've got two ways to do it: the manual way and the CleanMyMac 3 way.
How to Clear Log Files on a Mac Manually
- Open Finder and select "Go to Folder" in the Go menu.
- Type in ~/Library/Logs and hit Enter to proceed to this folder (pay attention to the use of “~” — this will ensure that you’re cleaning user log files, not the system log files).
- Optional step: You can highlight & copy everything to a different folder in case anything goes wrong.
- Select all files and press Command+backspace.
- Restart your Mac.
Note: We recommend that you remove the insides of these folders, but not the folders themselves. Also note that some system applications, like Mail, have their own logs stored elsewhere.
Remember, if you want the additional space from cleaning these log files, be sure to empty your Trash. To do this, Control+click on the Trash icon in the dock and select “Empty Trash.”
In addition, some log files can be found in the /var/log folder, but not all the items contained therein are safe to remove. That’s why it is safer to remove log files using a Mac cleaning utility like CleanMyMac 3.
