My 2015 MacBook Pro 15 inch's screen goes black for a second while the apple progress bar reaches half while booting
I'm getting this weird glitch happening every time I boot my laptop.
I turn on my MacBook Pro, apple progress bar reaches half and then for a second the screen will black out and then will boot normally. Before doing a full cleaning of the internals this would not happen.
Tried resetting NVRAM and SMC but no avail.
Has anyone ever encountered this actually? I scattered across the internet but nothing came up for this issue. Reinstalling MacOS is my last hope but I have some feeling that it's not associated with that.
Any help will be appreciated.
MacBook Pro 15″, macOS 11.2
