I'm new and I cannot Add a OSX project (all github repos are under Linux)

Hi Community! I bought an account for testing your OSX build service for my startup. I’m not able to select OSX from Add project… all my github projects are shown under Linux… but I bought specifically OSX for building OSX (ios) and testing parallelism… Your documentation gives no clue… I called to Support by phone but he just sent me this page: https://circleci.com/docs/ios-builds-on-os-x/

This is the screenshot showing that my repositories are only listed under Linux when adding a project and NONE for OSX… I only want to try the subscription I paid for OSX…

Please help me , Thanks!!!
