These issues can be a serious problem for those who have spent money on others virtual reality mirrors that interact with SteamVR using them on your Mac, because now you won't be eligible for the next versions of the platform and you'll have the opportunity to stay where you are now. What's wrong with most of these is that they haven't announced it beforehand, but are up for the night.
Valve False: there are more Macs than Linux users
The only thing that escapes the situation is that, according to Valve developers, they stop supporting MacOS because they want to focus their efforts on Windows and Linux
You just have to see Steam hardware stats to see it.
It's true that when we compare Mac or Linux and Windows usage, their usage is taken into account in both cases as Microsoft's operating system includes Steam usage, but they say they will focus their efforts on Windows and Linux, leaving MacOS to slow down when they have five times as many users as Linux, causing delays. Why does Valve lie to users when it's so easy to look at?
In any case, it is true that not many MacOS (or Linux) users have any realistic operating systems, since neither of these two games are designed for games and, in fact, developers are focused on the long term. on Windows only. However, when Valve releases SteamVR for MacOS, suddenly removing such support is an impossible task.
How to continue using SteamVR in MacOS
If you have planted real mirrors and want to continue using them on your Mac, you can continue to do so, even though you will be forced to always use the same type of SteamVR without updating it.
How to make it accessible to Steam -> Right-click on SteamVR -> Properties -> Betas and select SteamVR (macos).
This way your device will continue to work on "legacy" (old) versions of SteamVR. Something is something, as we mentioned above, because it would be far worse to withdraw direct compliance and force MacOS users with virtual reality apps to either switch platforms or sell their VR glasses.
