My MacBook mid 2010 keeps shutting down while boot
My Macbook mid 2010 keeps shutting down while boot, I first installed MacOs Yosemite that's when it started. It kept crashing and while boot it displayed some weird command thing on the left. I installed Sierra (not high sierra) the crashing is still going. Now it's "running" MacOs Sierra please help
Ist dies eine gute Frage?
