I actually worked for a large School System that [at least initially] was COMPLETELY a MAC iOS shop. Working in Building Services, we found 0 "Real-World "
[ HVAC, Security, Fire Alarm, Communications] systems that could be programmed or controlled without Wintel equipment.
Life was a challenge....

No idea what years this happened, but, OS/2 was actually a WIN platform that actually worked. It ran DOS and WIN better than DOS/WIN itself ran, and OS/2 itself was a superior multitasking OS that WIN has never been able to match. OS/2 was the system we should all be running at home, and in the office. It was bullet proof, and brilliantly designed for the home and commercial user alike. UNIX was pretty much only for gear heads and big business applications and while it could have been designed to work for the casual user, it never was. LINUX is probably as close as UNIX comes to what you call a residential OS, but it was always a day late and a dollar short. OS/2 was it, and IBM killed it for VERY suspect reasons. The entire computing world has suffered because of the shenanigans of MS, IBM and Intel.

OS/2 was like many of IBM’s products which were technically superior (like Beta vs VHS), but failed in the marketplace to other less elegant technologies such as Token Ring vs Ethernet and SSA vs FibreChannel. When OS/2 failed, it took HPFS with it. I will add that my nextdoor neighbor was an IBM mid level SW development manager and his company laptop had OS/2 installed. After some period of frustration, he brought it over and asked me to install Windows on it. Interesting how the world turns. OS/2 allowed virtual machines and now most data center servers run Linux platforms running some version of virtual machines such as VMware.

The current MacOS, iOS, iPadOS, WatchOS, and Apple TVOS are ALL based on BSD UNIX, and have been since the inception of OSX on March 24, 2001.

UNIX programs run on Macs from the Terminal command line. Terminal.app is found in the Utilities folder in the Applications Folder on the startup drive. You can drag an alias of it to the dock and have one-click access to it any time... Once you're set up as a user on your Mac, you are ALSO set up as a user in UNIX.

There is also a Terminal User Guide under Help in the Terminal application itself.

What can I say. Your neighbor was a computer moron. A software development manager that needed a neighbor to remove a great OS and install the worlds worst OS. You would have to be close to computer illiterate not to be able to do what your software development manager couldn't manage.

I can only add the IBM managers were not always technical. He was not a moron. He was quite successful and well regarded at IBM, but not especially technical, and his degree was not in a technical or engineering discipline. When I worked for IBM in the mid 60s on the 360 system, fairly early in your career, you were given the choice to pursue the technical/engineering side or management.

I didn't say he was a moron, I said he was a computer moron. Plenty of brilliant people are computer illiterate. Just very very hard to imagine a software development manager couldn't figure out OS/2, designed for the consumer market, or install DOS/Windows, designed for the computer illiterate market.

Sort of forgot about OS/2.
Sort of came & went ...
Couldn't afford Big Blue anyway .
