A bug report about this has been moved to "Confirmed/Planning to Address", so at least they're aware of it and will hopefully have a fix soon.

That said, the complete lack of communication and that they're still selling the mac version (with a warning M1 isn't supported but this also affects Intel macs afaik and no warning about 12.3) is very disappointing and worrisome. The teams communication, attention to detail and consideration for the player experience is something they are known for. It feels like that's changed recently on a few different levels, including this issue.

I wonder if they're readying to drop support entirely for Macs. M1s aren't exactly cutting edge at this point and while ffxiv worked well on them (till this patch!), there's still no official support or word on any of this since December.
