Question: boot up weird
My MBP mid 2012 recently upgraded to macOS High Sierra and every since I have a slow and weird boot up, Prior to the upgrade the laptop was very quick to boot up. Now the progress bar gets about 2/3rds across then stops and thinks about it; the screen then goes blank and after a few seconds I get a black screen with the progress bar in an orangeish surrounds and then it completes.
Can anyone tell me what the issue is
MacBook Pro with Retina display, OS X El Capitan (10.11.1), 512GB flash storage; 8GB RAM
