rebooting apple macbook pro 2011 yosemite

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. The solution for me was to restart the Mac just pushing AltĪrriving at this point you need to select not your MacintoshHD but the one on the right instead which is the image of your Mac.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.

Shift+Alt+Cmd+R : For the internet reinstall but the problem still persists.

Cmd+R : For the normal reinstall but the problem still persists.

You already tried to partition the disk multiple times but it keeps erroring with the Error: -61 I believe you followed the official guides and you tried to factory reset your Mac and you find yourself in this situation: the disk is locked and you cannot select it for re-installation
