Icons on the desktop may slow down Mac? When I ask a question about if I run too many process will slow down my Mac for Magican measured my Mac is high CPU usage. A Mac user tell me the icons on the desktop may still influence the performance of my Mac. Is this true?
Reputable sources like Macworld indicate that the Finder draws non-generic Desktop icons the same way it draws open windows, and the more of them there are, the more memory and processor time it takes to refresh the Desktop. I have not found any sources that indicate this is a major factor in system speed, but yes, more custom icons on the Desktop take more resources when the computer redraws the Desktop.
