1. Where can I find out how to use osx to its fullest potential? 2. What do I do about all of the .dmg that are just sitting on my desktop? I've downloaded some things and now I don't know if i should delete the .dmg files? 3. Why does a folder open up and I have to click another icon whenever I want to use Firefox? 4. Why, whenever I want to use an app I downloaded, does a new icon appear that looks like a disk drive. 5. Is there anything on a Mac that is like add/remove programs in windows? or how do I uninstall programs? 6. If is add and delete a lot of files, is it like windows where I have to run disk cleanup and disk defragmenter? 7. Does iTunes for mac copy all of my music files into another folder, meaning that I would now have two of the files on my computer? How can I stop this from happening? 8. Is there anything similar to the start bar on my mac, or everytime I want to use an app do I have to access it through my mac hd? As the title says, I am completely new to mac. I would be willing to read if there was a manual, but I never received anything with my computer. Any help anyone can give regarding these questions would be greatly appreciated.
