My Macbook Pro Retina takes a long time to turn on?
I don't know when is exactly this started but I recently updated to 10.10.3 and did not install any new applications. When I click the power button the screen lights up but it takes about 1-2 minutes for the Apple logo to pop up. After the Apple logo appears, the Mac boots up fast as usual. My MacBook Pro Retina used to just take seconds to turn on and the Apple logo used to appear immediately. One day this just started happening. What does this mean and how can I fix it?
MacBook Pro (Retina, 13-inch, Mid 2014), OS X Yosemite (10.10.1)
