Antwort auf „not booting osx appears a folder”I was having the same issue with my new old macbook. I just bought a new internal hard drive. i installed it, and started it up with the disc that came with it and nothing. the new hard drive doesn't appear on the installation screen nor in disk utility. i'm absolutely clueless as to what to do. i've googled for hours to no avail. anyone mind giving some guidance?
