When building on macOS 12 we get:

  block/file-posix.c:3335:18: warning: 'IOMasterPort' is deprecated: first deprecated in macOS 12.0 [-Wdeprecated-declarations]
      kernResult = IOMasterPort( MACH_PORT_NULL, &masterPort );
                   ^~~~~~~~~~~~
                   IOMainPort

Use IOMainPort (define it to IOMasterPort on macOS < 12),
and replace 'master' by 'main' in a variable name.
