Okay so I just joined this forum, hoping for answers to many questions of mine, so I guess I'll start asking.. I got my MacBook Pro 15" 2.53 GHz about 1 month ago. The operating system when I go to "About This Mac" says Mac OS X 10.5.8. This isn't Snow Leopard is it? I'm guessing I should take the CD of Snow Leopard that came with my Mac and install it. I thought it was already installed. Anyways, yes/no do I need to install it? If it's not installed, I think I will... **I REALLY NEED TIPS FOR THIS, JUST STUFF I CAN DO REGULARLY TO HELP WITH THE PERFORMANCE AND SPEED? THANKS!** Now I really want to make sure my Mac will always be fast and consistent and not slow down like PC computers. With PCs, you get them and they are great for the first while you have them and they just get super slow after a while. I really want to keep my MacBook Pro fast and safe and clean. Any tips on this? I plan on using it for at least 4 more years. But any tips you have to keep it fast, running well, and all that so in 3 years it won't slow down on me and stay fast like I just got it? I pretty much have all the programs the Mac comes with, just with 3 or 4 additional ones I downloaded from their site. So, your tips? Also, is this good for boot time and reboot time? 32 seconds average for boot up. 5 seconds for shut down (I have all the programs closed most of the time when I shut it down) What are boot up and shut down times that aren't really that good so I can compare? Thanks. For the most part, my Macbook Pro has been really good so far, it sometimes takes long to close programs or if I click something it will bring up that rainbow circle thing as my cursor and will take a little extra time for the Mac to do what I clicked. Thanks for all your help!
