Hi everyone. As a first time mac user this is my first post on this forum and unfortunately not one I am happy to make. Two weeks ago I bought an old iMac 24" (early 2008) and although a bit old it still worked beautifully. I froze every now and then and I was told that a reinstallation of OSX would be advised so I followed an appleguide on how to do that but unfortunately I've been sitting at "This item is temporarily unavailable" for the better part of a week. Not being put off by a challenge, I thought that it must be simple enough to make a boot USB and install the OSX that way. Boy was I wrong.. I dont have another mac so I'm using a windows PC to do this. I've followed the guides from around the net and tried powerISO to make a bootable USB to OS X, tried to make one with transmac and even gotten 2 other DMG files (mountain lion and another mavericks) I've even done a virtualbox installation on my windows PC and saved the Yosemite installation files to make a bootable USB and still, every single time I get to "This item is temporarily unavailable" I can boot from the USB but when I get to disctools and select recover, machine is verified at Apple, I type in apple ID and pass and next thing I know I'm sitting at the same frustrating error message... So; what are my options? I live in Denmark so going to an Apple Care center og Genious bar isn't an option as they dont exists. I am completely clueless as to how it is even possible to lock myself out of a computer as thoroughly as I have done. Really hope that someone can help me. Kind Regards jake.
