I've been playing on a PC with no issues. I purchased a mac mini because my PC is dated, then purchased the mac version of FF. It downloads and installs OK, but when I log in, the window goes black and it never recovers.

I submitted a ticket, followed all of their directions which did not fix it. They said if their solutions did not work, then my router or ISP is blocking the game. This cannot be the issue as I can play on my PC and there are 2 other PCs and 1 other mac that run off the same router and network as I do. I replied with that information but have not heard anything else since.

Here is what I have tried and my system specs:

From Tech Support:

Please make sure all background applications (including anti-virus programs such as Norton, Kaspersky, etc.) have been disabled and/or closed to minimize game interference.

Ensure that the latest version of Safari is installed on your Mac (even if you don't use Safari). Once Safari is up-to-date, please open the 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 your Mac OS. Once this process is complete, please re-launch the FINAL FANTASY XIV application.

I have also uninstalled and reinstalled the game

System Specs:
macOS Big Sur Version 11.4
Mac Mini (2018)
3.6 Ghz Quad-Core Intel Core i3
8 GB 2667 Mhz DDR4
Intel UHD Graphics 630 1636 MB

73 GB available storage

8 GB Memory

Any help would be appreciated. My PC is laggy and I'd really like to use the new system.
