“Remember the first time you started up your Mac? Hearing that lovely tone you thought would never get annoying and seeing the beautifully designed Apple-centric Boot Image,” Ian Spence reports for Mactuts+.
“It sure was a special moment. But now the love you once felt is gone, and you spend a little too much time staring at the boot image rather than actually using your computer,” Spence reports. “It’s true, over time your computer will slow down and stop working the way it once did.”
Spence reports, “Much like an automobile, your computer needs regular maintenance to keep it running at its peak-performance. The more you drive your car, the more “gunk” will build up in your engine. Over time, this “gunk” can impede the performance of the engine. The same applies for computers. To keep things running smoothly, your computer is constantly caching files. If this cache is never cleaned, over time it can become quite large, and eventually slow down your computer.”
