After reformatting I got to the setup screen after the cool intro. I noticed several problems. When on the screen asking about transferring files from another computer I chose no since I have none to transfer. But after choosing my option and trying to move forward it sat on that screen for a while until it finally moved forward. It didn't do this before. On the screen where you'd set up your internet connection and it lists available wireless networks it was slow on there too. It took me a while to move forward after choosing a different option. It took a while to recognize that I had hit a different option. Again, it didn't do this before. Under the internet sharing option it listed an option called bluetooth DUN. This option wasn't there before. If I recall it only used to list ethernate and airport under these options, but bluetooth DUN was the first option listed. I reformatted again because this seemed too strange, but even though ethernate was listed first bluetooth DUN was still is this listing. On the second reformat I got a message when turning airport off. I was dumb and didn't write the message down, but I believe it said something about airport power. Again, I didn't get this message before. Not when I first set up my Mac and not on the first reformat. None of this has happened before. It bothers me. What's wrong?
