You may not have even noticed your computer slowing down, possibly because it happened over time as you added more items to the Desktop.

Having all these thumbnails in the RAM slowed my Mac to a halt. This means your Mac can become extremely slow. The tool is always ready with previews, so when you have a lot of documents on the Desktop, all those previews will have to be temporarily stored in the RAM. While Quick Look is a fantastic tool to have, it will be your enemy if you keep Pages or Word documents, images, videos, music with artwork, and anything else it supports previewing on the Desktop. There are many different file types supported, from MP3 and AAC to JPEG and MP4. It allows you to select an item and preview it with a quick tap of the spacebar. Quick Look is one of my favorite features in OS X. In this tutorial, I’ll outline several reasons why you need to keep the Desktop clear and explain how to do it more effectively. The thing is, they probably don’t know how much it slows down their Mac.

These people have adjusted the icon size to 16x16 pixels just to fit it all on the display. I usually don’t have to mention the Desktop, unless it’s really bad. I usually ensure they have enough RAM to run the latest version of OS X, update everything, clean out some caches if the hard drive is near full, and advise they reorganize things. Over the years, I’ve repaired many computers.
