Hello, I am moving to an Apple very soon - can't wait ! However, I was wondering if there are any optimizations that need to be made to OS X to keep it in top running form. For example, on a PC it's usually good to run DEFRAG or SCANDISK every now and then, so your operating system can continue to run smoothly. Is there somthing like this for the Mac? Does the operating system naturally slow down over time. I appreciate any help you can give me before I make the switch. Thank you!
