Mac updating boot caches
System cache files are generated by OS X and, unlike application cache, have nothing to do with the user.The hidden system caches are mainly created by the apps that run on your Mac.
Some app developers keep important information on cache folders.While most apps will handle cache management on their own, and Mac OS will handle some other cache type files directly too, more advanced users can manually intervene and clear out their own cache and temporary files from a Mac as well.To be clear; this is not a recommended task, nor is clearing caches and temporary files on a Mac something that you should need to perform.After a fresh backup has completed, here is how to delete and clear cache and temp files from the active user: * The caches folder will contain many nonsensical file names and folder names, with names like “com.apple.i Tunes” and “com.apple. To find a specific app cache, you’d look for a folder of file that matches the name, for example the contents of “com.apple. This caches and temporary files folder is not intended to be user facing or user friendly, so don’t expect it to be.If you are aiming to clean out web browser caches, a better approach is to empty cache in Safari on the Mac or empty cache in Chrome on the Mac, both of which can be done directly from the web browser apps themselves.You should always back up your Mac before performing any procedure like this.
Backing up insures that if you mess up, or if something goes awry, you have a recent backup handy to restore the computer to. Backup your Mac with Time Machine before beginning.
