I freak out with this guys making the NeXTstep stuff for mac OS many years before than 1997 Steve Jobs.
http://www.tenon.com/about.shtmlTenon's efforts at integrating workstation-class applications and UNIX system software into "mouse and menu" PC software and hardware gave rise to a Mach kernel-based UNIX for Mac OS. This unique product, MachTen, was selected by MacUser Magazine as a Best Connectivity Finalist in 1991. In 1994, MachTen was selected by Open Computing Magazine as a "Best Product of the Year". Two years later, XTen, Tenon's X Window Server for Mac OS, was selected as the Macworld Editors' Choice.
For many years, Tenon's UNIX for Mac OS gave Macintosh administrators the strength they needed to fully integrate Macintoshes into the corporate enterprise. Likewise, University system administrators made good use of Tenon's UNIX-style file and printer sharing and full suite of UNIX-style networking capabilities. The strength of UNIX, the beauty of Mac OS, Tenon's banner cry that was later embraced by Apple when they debuted their new Mac OS X.
