4.15 distribution IOS Send build with Mac Mini

Hello everyone! I need help, I created a game on a windows 10 machine and I sent it to google play store and it all works. Now I want to put it on the Apple store of IOS, I do not own a Mac, I should buy it, to send a build to apple ( ITunes Connect) would suffice a mini apple Intel Core duo with 1,83 Ghz with OS 10.6?

Anyone have an answer?
