I see menus for Apps and this url https://creative.adobe.com/apps works in Windows, but not on a Mac. Mac shows only the /files area and if I type in /apps it says Not Found.
This link works fine for me on my Mac using Google Chrome. It might be a pop-up that is blocked for you...
Chrome also has a built in Flash plug-in, I didn't check if they use Flash for the pop-up login, but this is a login page for Creative Cloud. You can bypass it by logging in here:

The product isn't shipping yet, but you can get it for $29.99 if you own CS3 or newer (through the link above)
