I have recently installed macOS Sierra and sometimes my Macbook pro mid-2012 boots up properly (rarely). Otherwise it does not boot. When I try to boot it with cmd+v , it shows following text:
Read error 0x6
Kernel cache read error 0x6
It's been days since Im facing this issue. Any solution? Right now I'm asking this question using my Mac because it was of of those good times when it did boot properly.
