My new MacBook seems to start a lot slower than it used to. It used to go right to the screen with the apple, then into the OSX loading thing nice and fast. Now it hangs on a screen before the one that has the apple for a while. This screen is pure white. Then it goes to the apple one for longer than normal and then onto the osx loading which is nice and short. Now I understand that installing new apps will slow a computer, but this seems abnormal. I also uninstalled my 2 most recently installed apps, in case it was them. Any help is welcome, thanks. PS: Keep in mind I'm new to the world of OS X.
