Final Fantasy XIV game will not work on my brand new MacStudio M1 Ultra

The requirements for that game

https://na.finalfantasyxiv.com/system_requirements/

include:

* Models utilizing the Apple Silicon chipset (such as M1) are not supported.

THus, it should not work, and you proved it does not work, on The Studion Ultra since that is an Apple Silicon Mac.

Attempting to install or use a know Not Support version of an Application especially on Apple Silicon M1 Computer is folly in IMO.

Attempting to force the issue and make or attempt to make it work can and will either fail or is an invitation for disaster and comprising the Operating System.

Once that is done - it is unknown what the possible consequences may be to the Computer and Operating System.

If the XIVonMac developer's are not directly communicating the issue with Apple, then don't expect anything to be fixed. Someone has to prove to Apple that the bug is with macOS and not the third party app. Only the app's developer will have the necessary information to do so.

Also you need to keep in mind that any work arounds are usually temporary work arounds. They may work for years, but sooner or later something will cause a work around to break. Running an Intel game on an M1 which has a completely different & unique CPU & GPU is never a sure thing because even running a game on supported hardware with another unexpected GPU can lead to issues. It happens all the time on Windows if an unexpected GPU is involved. Game developers tend to take a lot of shortcuts within their games to make them perform properly (fast & with minimal lag) and these shortcuts tend to utilize unsupported system calls. It does not surprise me that an Intel game doesn't work well on an M1 Mac because games push the envelope on specific hardware and the OS way beyond standard apps plus Rosetta is making certain assumptions about the Intel apps being translated which may not pertain to this particular game. Rosetta is not perfect, but it does a pretty good job for standard apps and that is all Apple can hope for by providing Rosetta for interim support.

It is always up to the app developers to ensure their apps work regardless of what is causing a problem (if it is an OS bug, then it is up to the developer to report & work with the OS manufacturer to resolve the issue).

Certainly you didn't buy this expensive computer just to play a single game. Yes it is unfortunate that the game won't work. This is why so many people keep old computers so that they can use their older software. Welcome to the club.

Except there is no guarantee Apple engineers see this. We are a community of users.
