I have a Macbook that is about 2.5 years old. In the past few weeks it seems to have been running a little slower, so I wanted to do a restore. However, I do not want to restore it to its exact form, as one would after a HD crashes. Rather, I just want to clean install the OS, and then restore apps, music, documents. I did an erase using Disk Utility last night prior to installing Snow Leopard. Thirty minutes later, I had a brand new computer. When I plugged in my external, it took a while but it did install my apps. The problem is none of them seem to work when I click on them due to "access" errors. Furthermore, when I later tried to restore my documents I was having trouble getting Time Machine to even see read them from past folders. Instead I was just seeing empty folder after empty folder. Please advise.
