View attachment 1933670Hello!
I installed a new ssd on my MacBook Pro mid 2014 with the WD Blue SN550 + Gigabase SSD Adapter on Amazon.
Last night I installed Big Sur 16.2.1 on it after installing the new SSD and shut it down when I was finished with all the things.
But now I started my Macbook again, but it does nothing. Just shows me the black screen, no sound, nothing is making any noise.
Then I opened it again and put the old ssd in it and still nothing.
The battery is reconnected and everything, I just don‘t know why it is not starting. Also tried SMC and holding the power buttom a while but still..
Battery is working because if I plug it in it shows the green led.
I hope that someone could help me, I really need it for my studies
🙁
