My new Macbook Pro is behaving oddly when I open the lid after having put it to sleep by closing the lid earlier in the day.
The system resume process starts, but then gets stuck part way through. The gray and white bar that appears partly loads but then stops and does not progress. I've let it sit for over an hour like this and there has been no change.
Laptop is only two weeks old, bought new from Apple. Has Mountain Lion on it. Is not a retina display and not a Solid State hard drive.
