Removing Caches and other Temporary files can save space on your hard drive and in some cases even stop apps behaving erratically or sluggish.
The following steps will show you how to safely remove Cache, Log and Temporary files from your system. Removing these files triggers the applications to build a new file when it’s next launched. Cache and Log files get larger over time and can become corrupt causing system issues, forcing these files to be rebuilt can result in better system performance.
Deleting Cache and Log Files Manually on the Mac
There are three sets of Caches in OS X, the User Cache, the Browser Cache and the System Cache. The following steps will explain how to delete all these files from your Mac.
1. In the Finder Menu, under GO choose “Go to Folder” you can also use the shortcut: Shift + CMD + G
2. In the Go To Folder dialog box enter: ~/Library/Caches
3. At this stage it might be a good idea to quickly make a backup of the files we are about to delete, this is optional but it only takes a moment and in the very unlikely event we have a problem we can just put these back where they came from. The simplest way to make a quick copy is to hold the alt key and drag the folder to your desktop.
4. We then need to select all the files in the Cache folder, you can do this by first selecting an item within the Cache Folder and then going back to the Finder menu, then choosing Select All under the Edit Menu or by using the shortcut: CMD + A
5. Once you have all the files selected you can either just delete them by dragging them to the Trash folder in your Dock and then Emptying the Trash in the Finder main menu.
6. You then need to repeat the above steps but by replacing “~/Library/Caches” with: “/Library/Caches” and “~/Library/Logs” if you would like to remove your Mac’s Log files.
