Yeah, this is kind of “core” stuff and sometimes strange values get written there or corrupted or something and weirdness ensues. Caret blink time (insertion point rate).Serial Port Configuration and Port definition.Since the dawn of Macs we’ve had what is called the PRAM-parameter RAM (you can say it like pee-ram or pram, doesn’t matter)-which stores stuff like this (from Apple support): It’s a good step to make sure nothing interferes with the resetting process.

The good news is that, you’re only a few key presses and reboots away from things (hopefully) being back to normal.įirst, before I get into the hows, whys, and wherefores of resetting the SCM and PRAM, remember…while these are generally safe things to do (and the instructions are freely available on Apple’s support section), make sure you have a recent back up and critical stuff is backed up on an external drive or USB key or something.Īlso I’d disconnect all drives, speakers, external displays and keyboards before you try this stuff. And while doing stuff like fixing permissions can fix some strangeness, this is strangeness on a deeper level. Yeah, these aren’t problems that simple rebooting often fix. Is your Mac acting just… odd? Stuff like drives not appearing, screens not adjusting correctly, Bluetooth problems, AirPort non connecting? Maybe your fan is running non-stop or your battery has said that it is 50% charged…for two days…and your MacBook is plugged in.
