Is Godaddy.com hosting Mac-compatible?

I'm trying to purchase a domain and website hosting on Godaddy.com. It's asking me what plan I want, and what operating system I have: Linux or Windows. I use a Mac. I have neither (I think; I'm running OS X Snow Leopard). Please, no snappy comments about PC vs MAC; I want my question answered, not a bloody war on my hands. Thanks.
