Yes.
Using the kernel developed by Next was a huge deal. It doesn't change the fact that 25 users ago Apple was an absolute mess (thus the need to purchase Nexr for the OS (and CEO).
Os9 was an absolute outdated disaster.
And? Are Windows 11 problems negated because of an ancient Mac Operating system?
Can you explain why that is the case - since you brought it up a number of times now.
This is a real issue. My Digital radio classes, which during Windows 7 days, took two classes to have everyone's systems running, then transition to the important details that make the software easy to use. My last class took months for the Windows users, as Windows 11 updates borked their installs. Either through Blue screening, or endless reboot loops, or if the software survived the update, plain weird stuff happening. On the Windows 11 laptop I was using, the programs stopped running. Microsoft in its wisdom, moved the programs and files to OneDrive. changed my username to my Microsoft account, and removed my local name from everything. The eventual fix was uninstalling OneDrive. I could blame that on myself if it happened immediately, but it didn't.
It was not lost upon the class that I switched over to my Mac and it just worked. I had to do that because it was going to take a while to restore my Windows machine to function. And my students were having similar problems.
Meanwhile, My Mac and Linux machines just cruise along without issue. Installed software stays working, Updates don't bork the machines or software. And that is what we want.
My students have asked for a new class - an introduction to Linux. They are pissed off at Windows 11, which is regressing.
