Thank you, Martin. Good to see that we can continue to use
- defined __APPLE__ && defined __MACH__ to test for macOS >= 10,
- defined __aarch64__to test for 64-bit ARM CPU.
- defined __ARM_PCS_AAPCS64 for the function call convention.

With Xcode 12.2 on arm64 macOS:
$ : | gcc -E -dM - | sort > predefs.out
$ grep -i '\(apple\|mach\|arm\|aarch\)' predefs.out
#define __AARCH64EL__ 1
#define __AARCH64_SIMD__ 1
#define __APPLE_CC__ 6000
#define __APPLE__ 1
#define __ARM64_ARCH_8__ 1
#define __ARM_64BIT_STATE 1
#define __ARM_ACLE 20
