macOS Title bars in MuseScore are still bright in dark mode

macOS is in charge of selecting the color for the title bar based on whether or not Dark Mode is enabled system-wide. To enable Dark Mode system-wide, open the System Preferences app, click General, and change Appearance to Dark.

If that fixes it, we can close this issie as being by design

Okay, I see now that this is indeed an issue with the official builds of MuseScore. My self-builds do not have this problem. Maybe that is because I am using the latest developer tools from Apple.

Which may not yet be available im Travis CI or cause the result not to run on older macOSs anymore?

As long as CMAKE_OSX_DEPLOYMENT_TARGET is kept at 10.12, the result should run on macOS 10.12 or later. And macOS 10.14 and Xcode 10 ought to be available in Travis CI, but I can't really say for sure.

Fixed with commit fe96c2b.

I tested the latest nightly from http://prereleases.musescore.org/macosx/nightly/ and it does not have this problem, whereas 9d7f4e4 does.

Was fixed in 3.2.1, but is back in 3.2.2, as the corresponding fix (building it on macOS 10.14, using XCode 10.2) had been reverted to avoid a significant performance drop on macOS 10.14+ machines

relates to #292477: [EPIC] issue with dark theme

Maybe this can be revisited builing on macOS 10.15 w latest Xcode? The light title bars feel somewhat wrong in dark mode.

See https://github.com/musescore/MuseScore/pull/6652 is set to fix this

Fixed in branch 3.x, commit a4cfffe7db

_Fix #290946 - Change macOS window title bar color for Dark theme

Previously, when you selected MuseScore's Dark theme,
the title bars of the windows on macOS stayed light.
Now, they will also change, along with the MuseScore theme._
