There are usually no valid 32 bit addresses, i.e. the first 4GB are not mapped.

  That might be their point. As the OP quoted > any virtual address below 0x100, 000, 000 is invalid. That kinda suggests that all 32bit addresses are inherently invalid on 64bit MacOS

    Not inherently, it's just a linker default. You can run 32-bit processes through WINE.

      Only in Rosetta. On arm64 these binaries will not be allowed to load.
