I'm running Sierra on an old 2012 13-inch MacBook Pro. Everything slowed to a crawl on Thursday, presumably from the same ocsp problem everyone else experienced. My laptop eventually shut down after freezing totally, and upon reboot, it presented me with the prohibitory symbol (?). I figured it was a problem with my hard drive, but couldn't find anything wrong -- reset the PRAM/SMC, ran Disk Utility's First Aid function, etc. Still couldn't boot up.
So I left it alone, and the next day, it suddenly booted up fine. Still slow, lots of spinning beach balls, but not as bad as before. Each time I've tried shutting it down, it gives me the prohibitory symbol, then if I let it sit for a day, it boots up fine, but runs slowly. It "works," but it's horribly slow -- I can't use the machine for anything too stressful, or it starts locking up. It does seem to run without issue if I turn off the Wifi, which makes me think it's a lingering symptom of the ocsp issue.
This came out of nowhere. Anyone else having similar problems? Any ideas what the cause could be?
