    Applications

    If you can't find "Macintosh HD" under "Devices" in Finder, go to "Preferences" and under the "Sidebar" tab, check the "Hard Drives" option. "Macintosh HD" will appear in the left column.

  • You can set Mozilla Firefox as the default browser on your system. To do this, go to the "Firefox" menu, "Preferences", "General" and check the "Make default" option.

    • Since October 2015, representative certificates generated by FNMT depend on the root certificate AC Representation and are issued under FNMT -RCM.

  • Root certificates can be downloaded from the CERES website under "Certificates", "Technical Support", "Downloads", " FNMT Root Certificates". If your certificate is issued under FNMT -RCM, download the root certificates AC FNMT Users, AC Representation or Public Administration (AP) , as appropriate. Check both trust purposes and click "OK".

    You can check that they have been installed correctly in the "Authorities" tab of the Firefox certificate store, within the browser menu, under "Preferences" , "Privacy and security" , "Security" , "Certificates" , "View certificates" . To review the trust settings, select the root certificate and click "Edit Trust" . Remember that both purposes must be marked.
