I got this error during boot on my 2011 MacBook Pro. I'm not sure if a bit is flipped. I looked at the binary and it looks like a bit was flipped. 0xf = 1111 0xb = 1011 so it looks like a bit may have been flipped is there a way to tell if there is a faulty error in a registry or if this is just an error that occurred due to some anomaly?
