Hey guys, I contacted apple support and the employee guided me to try booting my mac with some special short cuts. Such as hold command and option and the power button. Hold P and R and Command and Option I think. I don't know what it does, but now every time I boot my mac at the apple logo it flashes before it powers to desktop and when I turn my Mac off it takes over 20 seconds even when nothing is open. I remember it taking less then 5 seconds to turn it off. I don't know what the guy made me do on my boot up but is there a way to boot normally or do I have to factory reset everything?
