I have a MacBook Pro mid 2009 with El Capitan running on it.
I wanted to enter Recovery Mode and pressed cmd+R until the Apple logo appeared with a progress bar. After about 3 hours waiting the progress bar was complete but nothing happened. I waited another two hours but still nothing changed.
When booting in normal mode everything is fine and within a minute I can start working. Do you have any advice for me?
