How to Clear or Delete System Log Files on Mac OS X

Posted by on .

What are log files on Mac? Log files are extremely useful because they represent a record of what's going on with your Mac computer. They're essentially meant for post-mortem purposes when things go wrong, like when your applications act funny, your system hangs or something just shuts down unexpectedly. Using these logs, developers can debug the system and find vulnerabilities, and they're very handy when you send crash reports for specific apps.

If you have a computer running Mac OS X (macOS), these system files tend to build up over a period of time, which could possibly slow down your computer. The question is, are they safe to delete? This is what a lot of non-technical users tend to wonder because they're afraid it will break the system somehow. That's not at all true. Removing log files is quite safe, and there are several ways to do this. This article offers an overview of two different methods to remove system log files.

Note: If you've been sending crash reports to Apple or app developers whenever an application hangs or automatically shuts down, these log files will be sent to them for debugging purposes. If that's the case, then whatever you have on your computer has already been sent to them, so you don't need them anymore unless you're a developer and want to understand what went wrong. If you're a regular user without much technical expertise, feel free to delete them periodically to lighten the load on your computer's resources.

Part 1. How to Clear .log Files on Mac Manually

To delete these system log files manually, you have to know where they're stored. The default location is usually within the Library folder, where you'll see a sub-folder called Logs alongside other system folders such as Updates, Extensions, Components and several more. To access this location, you'll need to use the Finder app. Follow the steps shown below to delete your system log files manually.

Step 1. Open a new Finder window and navigate to the Library folder, then search for the Logs sub-folder. You can also search for ~/Library/Logs in Finder, to take you there directly.

Step 2. You can select individual log files, then right-click and select "Move to Trash".

Step 3. Go inside the sub-folders within the Logs folder and do the same with the system log files found there.
