I’m a total newbie here any trying to figure out how to use wordpress.org (not wordpress.com) with a domain I purchased from GoDaddy.com a month ago. Also I have the handicap of being a Mac user (mistakes were made). Thanks in advance!
WordPress.org is a web-based platform, for the most part it can be accessed the same on Windows or Mac. You can use Managed WordPress hosting (more streamlined) or one-click install in a cPanel hosting account (more flexible). If the domain and hosting are in the same account it should automatically connect when you set-up the account.
