This isn’t true - it’s supported on the OSs it was developed for as of the last update in 2023. This is to be expected.
Live is actually a good example. Live 11 was still in production and got a final update this year, so of course it’s supported on current versions of Sequoia. But 10 isn’t. Its last update was in 2020, and it’s not supported. Live 11 will most likely NOT be supported on MacOS 16. It may not even be supported on Sequoia iterations going forward - no one knows. Going by release year doesn’t really tell you anything - it’s the last supported update. and the release cadence of the company. Ableton and SB are no where near the same cadence for releases, so it’s different.
Once software versions are depreciated, dev stops, and focus shifts to the new version. That’s just the way it is, and it’s that way for everyone.
This is a repeating conversation every time a new OS comes out, particularly on Mac. If UAD had their way, they wouldn’t allow anyone to upgrade unless they were good an ready, even if it takes years. They STILL haven’t gotten their drivers fully updated for Sequoia and Apple Silicon. When you update their components, MacOS still gives you a warning that “these people are using depreciated components which will stop working in a later version of the OS” (paraphrased).
I get it, but you don’t have to update your OS. You can if you want to, and if you want to be supported, you should plan for updating your software to follow suit. You can cherry-pick examples of companies that do things differently, better, worse, or whatever, but if you’re really concerned about this, then the solution is “plan for updates.”
In some cases, this even means new hardware. Were you aware that if you’ve purchased/upgraded to Logic Pro 11, that you don’t get all the features unless you’re running Apple Silicon? Pretty amazing requirement. Same for MacOS Sequoia itself - if you want all the features of the OS, Apple forces you to purchase an M-series chip.
Now, if Apple decides to shift a core audio component feature-set or development library to M-only in a future iteration, that means that ALL DAWs on MacOS would have to change their code or simply not be able to run on Intel. That probably won’t happen (at least all at once) but it’s the same thing.
Anyway, good luck out there. Have a good one.
