   Wow.   
      
   Wrong again.   
      
   It most certainly IS still Darwin.   
      
   Do you have an up-to-date Mac you can check this with?   
      
   Launch Terminal.   
      
   Type "uname -a".   
      
   You'll get this:   
      
   "Darwin .local 24.6.0 Darwin Kernel Version 24.6.0: Mon   
   Jul 14 11:29:54 PDT 2025; root:xnu-11417.140.69~1/RELEASE_ARM64_T8122 arm64"   
      
   Note that the OS (at the level of the command line) is "Darwin" and it   
   specifically calls out that "xnu" is the kernel.
