Different startup screens
Hello!
I am wondering and curious about my macbook when it is starting up. The startup screen have 2 types : grey and black startup loading screen.
The startup loading screen will appear grey if I press the power button once.
The startup loading screen will appear black if I force shut down macbook by press and holding the power button while on the startup screen that appears grey.
Is there any explanation of this? The startup is normal, no errors, only if the mac is starting up with the grey screen, there is minor problems while the mac starting up with the black screen is working fine. I am using Macbook Pro 15 Inch 2016. Thanks! Below are the pictures :
