I have had problems with the autorization of Digital Edition

and are now following the steps provided here: https://helpx.adobe.com/digital-editions/kb/error-e_act_not_ready.html#. However I dont understand this: Navigate to /Users//Library/Application Support/Adobe/Digital Editions and drag the activation.dat file to the trash. WHERE DO I NAVIGATE? I am using a MAC OS 10.10. My computer is installed for spanish, I am not sure whether that matters. I am installing adobe digital editions 3.0 to be able to read an e-book that I just bought.
