The minimum macOS version on which JavaFX will run is currently set to 10.10:
https://github.com/openjdk/jfx11u/blob/debbd07dfe122f550e6770cfe34b4bf1e7eaff05/buildSrc/mac.gradle#L54
defineProperty("MACOSX_MIN_VERSION", "10.10");
macOS / aarch64 (aka arm64) requires macOS 11.0 as a minimum in order to run.
NOTE: This issue was cloned from JDK-8265031. Rather than backport that issue to FX 11 and FX 8 in its entirety, we will only update the minimum macOS version for aarch64 builds (to 11.0). For compatibility reasons, we will leave the default macOS version at 10.10 for the older releases of JavaFX.
