Hi, I locked my mac through Find my iPhone and when I try to boot it again it appears an error message: "The Mac OS X Installation couldn't be completed". I run the last version of Mavericks and I can't figure a way out. Help me please!
Maybe try unlocking the device with find my iPhone? I'm not sure that you can actually do that, though. The only other thing I can think of is to reinstall the OS (google it)
I tried unlocking from my iPhone, no succes. I found something on the internet, in boot I pressed COMMAND+R, connected to the internet and this solved my problem. I love Apple so much.
