When booting up screen goes black and continues normally
Hello.
I got a MacBook Pro 17 inch of eBay. When booting up this MacBook Pro, it goes 3/4 of the progress bar, the screen than turns black and than shows the regular login screen.
Is there a problem with the GPU logic or this normal as the graphics are changing between dedicated and integrated? Both GPU’s have no problems as I checked by watching videos and doing browsing.

What is the OS-X version you are running on the system. Your system may need a firmware update.

It is running high sierra 10.13.6. It also is missing the apple hardware test. It gives me error -3403D
