I am fairly new to Macs and bought a New Mac Mini about a month ago that had Leopard as the OS X. I was very impressed with the Leopard system, but did upgrade to Snow Leopard as it was supposed to be the latest and greatest however I have had problems ever since I installed the upgrade. My time machine doesn't seem to be working, I am getting a lot of pin wheels when I click on various programs, etc. So I am seriously thinking of going back to Leopard 10.5, but not 100% sure how I go about that. Will it work if I just put in the re-install disc that came with the computer originally or do I need to go some other route? Appreciate simple directions. All the computer is really used for is surfing, e-mails and storing various pictures and documents so no real need for any advanced "improvements" that I allegedly may have gotten with the Snow Leopard "upgrade".
