Good morning and thank you for posting on the Final Fantasy XIV Technical Support Forums.

Please try the following troubleshooting steps:

- Ensure the latest version of Safari is installed on your Mac (even if you don't use Safari.)
- After updating, open Safari browser and make sure that all Browser History and Cookies/Web Data have been deleted.
- Please also make sure that "Cookies" are accepted and not being filtered.

Once these options have been adjusted, please run the Apple Update program to check that all firmware is up-to-date on you Mac OS. Once this process is complete, please re-launch the FINAL FANTASY XIV application.

-Make sure your fire wall or antivirus program is not interfering with the game

- Check to see if the following port ranges are opened on your router. You can contact your ISP and request they open them for you:
▼TCP
54992 through 54994,
55006 through 55007,
55021 through 55040
