Apple has been stuck with MacOS X 10 for some time only updating minor version if your hardware is supported. This was Microsoft's plans for Windows 10, but uptake has been so poor that Windows 11 is now in the pipeline. However, if Windows 11 is still going to be NT based then this too will be stillborn.
NT means New Technology. Apparently, Microsoft thinks that 1940s technology is new technology. (OS development has been taking place since the 1950s.)
My introduction to Mac started with System 7 and 8 at home. These used Creator ID to associate applications via the Finder in a similar way that Unix allows capabilities via Supplementary Groups and device files. Classic Mac OS just worked like other Non-Microsoft systems. Prior to that, I was integrating WFWG 3.11 and NT 4 into Samba NT domains using various flavours of Unix. We were an IBM (AIX) and Unix (Solaris) shop for critical applications and had actual terminals for critical application deployment.
Dragged everyone kicking and screaming through Windows 9X, 2000 and XP. Realised the futility of sticking with Microsoft and so rolled out SunRay on Solaris for certain classes of users. The accountants still had their Excel, but we charged a lot more per PC seat than a SunRay seat.
A loyal Microsoft user was explaining that everyone used to use the same version and now they do not. My reply was that with each version being worse than those before it, it is getting harder and harder. Old Windows was like bashing your head against a padded cell. New Windows is like bashing your head against concrete or thick steel.
Use of Microsoft Windows is now unequivocally counter productive. If you use it then you are either wasting your own time or someone else's.
As I maintain that Windows is just a monitor (not much more than DOS) with a GDI and a whole load of wrappers to waste CPU cycles, the monitor part could easily be replaced with a small library that can be run under an Operating System (OS).
The simple fix is to provide a wrapper for an actual OS that can manage resources. I know that Microsoft would not be interested in GPL GNU/Linux and LGPL WINE, but they could port their ABIs and APIs to FreeBSD, which though not free as in freedom has an excellent filesystem (ufs2 or 5xbsd) and hardware support. You can fork BSD and not have to share which is sort of what Apple has done with MacOS X.
This would allow native Unix/POSIX apps to use the FreeBSD runtime and X11. Windows programs could run alongside via the wrapper.
I use Debian GNU/Linux and have taken Chrome, Drive, etc. from the previous Chrome OS install on the machine with me.
Google do cloud better as both files and apps are hosted on servers with fibre network connections. Free software also has Broadway which can also push GUI apps via HTML 5. All that is needed for the desktop is just enough GNU/Linux to run Chrome. Your work just follows you where ever you login to Chrome. This is a good solution for the corporate desktop.
Apple also does cloud, but you need Pages, Numbers and/or Key Note installed on each device and must push morbidly obese Office files over the Internet.
I use free LibreOffice and Gnumeric on Apple MacOS and GNU/Linux as I am used to those apps.
