Regarding the End of macOS Mojave Support
Square Enix support for the macOS Mojave version of FINAL FANTASY XIV will end on Friday, September 16, 2022.
You will likely be able to play FINAL FANTASY XIV on macOS Mojave even after the end of support. However, after we discontinue support, we will as a general rule no longer be able to provide support for problems arising as a result of the operating system.
Square Enix may respond to requests for technical support regarding macOS Mojave issues after the end of support, but such informal support will be limited, on a case-by-case basis, and is not guaranteed.
Thank you for your understanding and continued support.
