Hi ! Im a newbie to Macintosh computers and I have the new Mac OS X 10.5.5. Im confused, is this a Leopard or a Tiger ? Also, if anyone has time to answer this thread.. Id like to ask for a recommended APP for my Macbook. I usually love to chat to my friends and relatives using the webcam, i also love to create videos and pictures. What im using right now is IMovie, Iphoto and the APP that is already installed here in my computer. Do you have other suggestions and where can i get them ? If there is a FREE APP, it would be great ! I also want to ask if you have ANTIVIRUS in your Mac and what do you use ? And is it OK to download the FREE Limewire ? Id like to download some MUsic because i dont have anything on my itunes. Pls. help a newbie like me. I am a little used to PCS but im a beginner to MAcintosh. thanks for reading and i hope to hear from all of you. PEACE and Advance Happy Halloween ! P.S. Also, i noticed i have Office 2008 12.1.3 UPDATE on the side of my screen. I dont remember downloading them.But i see it on my computer. What is this ? I tried installing it but it wont.
