I can't describe you how disappointed I feel about your decision to stop supporting the MAC client, I have been one of your most supporting MAC customers since September 2020 and now the news about your decision to drop support on the MAC client has taken me unprepared and hugely disappointed.
I expect game developers in the future to stop using OpenGL as their only jack of all trades rendering SDK and be more flexible exploring other alternatives more compatible with the different platforms existing today.
Even Windows is planning to get rid of OpenGL, so I don't know how you will survive chasing a dead horse, I think you should have considered Metal or other alternatives instead of using OpenGL for MAC OSX, this would have improved the game client performance and continue your support for MAC users. Other companies did it, so I don't understand why you don't. It's easy to stick with OpenGL and be a game developer working for a multimillion company, it's harder to be more knowledgeable with other rendering alternatives, for this reason I define your discontinued support to MAC users a business failure.
Please consider taking feedback about the product you sell as well, there are a lot of feedbacks on Reddit on how terribly optimised your game is and you should really start to work on some serious improvements because it's not possible to play GW2 on max settings without being affected by lag and poor rendering, not even a reasonably expensive computer could do it and GW2 is meant to be using a very old engine.
I will add a few links to enrich my feedback with useful information about OpenGL alternatives, in case your (well paid) developers didn't already:
The end of OpenGL, Vulkan: https://gamefromscratch.com/cross-platform-opengl-alternatives/#:~:text=Use Vulkan + MoltenVK&text=Vulkan is a lower level,graphical functionality in modern GPUs.
Metal (API): https://en.wikipedia.org/wiki/Metal_(API)
I have spent a lot of money in GW2 since I started playing the game and I honestly feel betrayed by your decision to drop MAC entirely.
I have a question for you, will the last things I have unlocked with gems be locked back if I asked for a refund or will they stay unlocked (for example all the living world content bought with gems)?
