I downloaded the theme to the Downloads folder on my iMac. I click on "choose file" on the Wordpress Add Themes page. This opens the Finder on my iMac. I go to the Documents folder and highlight the "uua-congregation" folder that was downloaded. I click "choose", but instead of uploading the file, it just opens the folder showing all the files and subfolders. Is this because the download wasn't a zip file; or if it was, the iMac unzipped it automatically? How should I proceed?
