Companion to musescore/muse_framework#295, which holds the actual CMake change; this PR bumps the muse submodule to it and adapts the MuseScore Studio side.

In short: the macOS deployment target was set as a normal CMake variable after project(), which shadows the cache entry, so -DCMAKE_OSX_DEPLOYMENT_TARGET=... and cacheVariables in a CMake preset were silently ignored — the cache said one thing and the build used another. It is now a cache variable, set before project() (which is also the only point where it still reaches the compiler checks that project() performs). See the framework PR for the details.

On this side:

  • CMakeLists.txt includes the new SetupMacOSDeploymentTarget.cmake before project(). MUSE_FRAMEWORK_PATH and MUSE_FRAMEWORK_SRC_PATH move up along with it, since the include resolves through them.
  • LSMinimumSystemVersion in both Info.plist templates now uses CMAKE_OSX_DEPLOYMENT_TARGET, since the MACOSX_DEPLOYMENT_TARGET variable that fed it is gone. The commented-out overrides of those two variables in src/macos_integration/CMakeLists.txt are removed too.
  • The submodule bump raises the minimum supported macOS version from 10.15.4 to 13.0.
  • macOS CI moves to the xcode-27 runner image. That image contains a single Xcode, which is selected by default, so DEVELOPER_DIR does not need to be set anymore. Note that the image is arm64-only and still in public preview; it runs macOS 27.

Verified on a configured build directory that the default, a -D override and a MACOSX_DEPLOYMENT_TARGET environment variable override all end up in both -mmacosx-version-min and the LSMinimumSystemVersion of the app bundle and the QuickLook extension.

📝 Walkthrough

Walkthrough

The macOS workflows now use the xcode-27 runner. The macOS workflow removes the Xcode 26.6 developer directory override and uses install-qt-action for Qt 6.10.2. CMake configures framework paths and the macOS deployment setup before project(). Both macOS Info.plist files now use CMAKE_OSX_DEPLOYMENT_TARGET. The muse submodule reference was updated.

Priority: ➖ Normal

Merge Risk: ⚪ Minimal · up to de62e

The macOS deployment and CI updates preserve the examined build contracts, and no repository-controlled validator blocks the new runner label.

Motivated by the fact that it is no longer possible to compile for macOS <11.0 using Xcode 27, and that a deployment target bump is likely required for #34896

please update PR

The deployment target was set as a normal variable after `project()`, which
shadows the cache entry, so specifying CMAKE_OSX_DEPLOYMENT_TARGET on the
command line or in a CMake preset had no effect at all. It is now set as a
cache variable before `project()`, which is also the only point at which it
still influences the compiler checks that `project()` performs.

The separate MACOSX_DEPLOYMENT_TARGET variable was only consumed by the
Info.plist templates, which now use CMAKE_OSX_DEPLOYMENT_TARGET directly.

I wonder about audacity, should we follow that pattern too? @cbjeukendrup

Yes, basically all changes from here should carry over to Audacity (except src/macos_integration, as I suppose Audacity doesn't have that)
