I have questions and concerns. From a friend i have heard that you cannot fully remove all information and applications when you delete them. He told me the apps and information will be compressed and stored in case you want to back up. How would one completely remove unneeded software or information from a Mac. This is also a concern on my pc, if someone could help me that would be greatly appreciated. I have a vague idea on pc, because i think you can delete all but the most restoration point. Also how do you create restoration points on a mac or pc; or set the computer to automatically do that?im sorry, my questions may not be too clear but your help would be appreciated.thank you</blockquote>
