Is OTHER wrong in the post ? POST : So a few days ago I sold an old Computer as I upgraded about a year ago. Before it went I restored the HD to remove any old data. 

For those of you not familiar with a Mac when it reboots (me a until a few days ago) you need an apple ID to reinstall the OSX after wiping the drive. 

The guy had already agreed to buy this when I let him know that I had restored the HD and currently the computer had no OS. He said it was no problem he had looked on google and he was sure he could fix it. 

Its now been about 3 days and he hasnt stopped trying to contact me saying it wont work and the OX wont install. It seems to be a common error from searching around the internet but he still keeps coming back to me saying its not working. I keep directing him back to online tutorials as I dont have the time nor do I actually care. 

However he has paid a few hundred dollars for a glorified paperweight at the minute but after he told me he can fix it I dont really care, AITA?
