I apologize if this question has already been posted. I have always been a Windows user, thinking about switching to Mac. What type of maintenance do you need to run on an Apple computer to keep it running smoothly? My experience with Windows is that you need to Update daily using Windows update to update Antimalware and various other Windows programs. Keep your virus protection up to date. I have Norton 360. And run the Scans. Run defragmenter at least every month or every other month. Run registry clean up frequently. Check the Problem Reports and Solutions page and install the fixes. Run Disk cleanup to free up some space. ETC. THANKS in advance!
