So I have been designing android apps and I want to move into Apple app development and I have been approved as a developer and everything and I have been able to design a few test apps on a windows machine without a mac. The only thing I can not do is complete the binary upload as it seems I have to use the application loader which will only work on OS X. So it appears as my options are to buy a mac to complete the binary process unless anyone can point out a way to do it on a windows machine which I have not found. If I can't do it on a windows I want to buy a mac, my question is can the mac be any operating system or does it have to be one of the later operating systems in order for them to work. Basically I am looking for advice as it appears as this is a great site for apple development support and I am sorry if I am posting this in the wrong section. I look forward to your answer and I look forward to exploring this site and forums more and hopefully become involved.
