Thank you for your response,
I think computer is fine, I have dealt with this particular auction company before and they would state if computer is damaged. They are auctioning assets of the company that filed bankcruptcy.
All I have is the model at this moment ,it is A1419 just like yours, they have 2 others but I am not sure if I will buy all of them...depends on final bid value.
I have contacted them to see what they mean by "wiped" and at this point I am assuming that hard drive is totally wiped (reformated). I will try to get them send me serial number or will go to see it myself.
I know for Windows, each computer usually has a tag with windows OS serial number so you can just buy or borrow windows OS CD to install and SN will be used to activate it your OS.
Now for Apple I am clueless on the process.... and if I am gonna bid to buy this computer I need to consider any additional cost that I might incurr after the pirchase.
