macOS Catalina is said to have dropped support for 32-bit apps. But how much of the support is actually dropped? Is it only that 32-bit libraries are no longer supplied? Or will 32-bit binaries, even if statically linked, fail to launch?
If 32-bit binaries can't launch, is there any supported way for a 64-bit app to request the kernel to create a 32-bit code segment?
