You got it almost entirely wrong... There are significant amounts of FreeBSD code in the Mac OS X kernel (the network stack, the VFS layer, several file systems, access control, security auditing and more). Mach provides only IPC, scheduling and virtual memory, IIRC. The rest of the kernel (including all device drivers) is proprietary Apple code. DES --=20 Dag-Erling Sm=C3=B8rgrav - des@des.no
