Out of curiosity, I set the permissions on my hard drive from “everyone” to “no access“. Actually,i was trying to change the permissions on my mac book air so that my hard drive would not be visible to everyone that could access my network share. Unfortunately, I did not know that changing it would effectively lock out the mac all together and the drive then turned into a blue folder with a red circle on it and just the gray screen of death with the perpetual wheel after reboot 😦
I restarted again and now I’m stuck at the gray screen with the apple logo. What can I do to get it back to normal?
