Sign in problem

Hi… I am trying with 12 words phrase , but not able to sign in my wallet… can anyone help me

are you getting an error message? where are you trying to login? Post more details

I’ve just created an account, and trying to login, I get… well… I can’t even press the “open wallet” button, stay greyed out on Safari & Firefox, using both the 12 word, and the URL/quick access password…

MacOS 10.12

PS: Why isn’t Iridium (Chromium based) supported???
