i have no idea what you mean. and not sure what 'normals' are, but the world is full of macusers who do professional work on their macs, or just surf the web and send email. 'everyone on the forum' is still less than 1% of the mac user base... and i stand by what i posted.
You can stand by your post all your life but you will never have admin as many Macs and Mac users as I have. I can 100% guarantee with Jupiterean levels of experience that 90% of Mac users don’t know Spaces exists (even when the accidentally trigger it), most don’t know anything about Mission Control hot corners, most don’t even know three finger Mission Control activation.
Most don’t even know command-tab. A basic OS feature that is around since 30 years and most still don’t use it.
Most still click on the Dock to multitask and they still move windows around to find the windows underneath. Drives me crazy when I see people do that at work and they all do it, so I stopped nagging them.
These kind of ancient behaviors are rooted in how people interact with real world objects. It‘a only a small group of users who are dedicated enough to learn all the features and gimmicks.
So Stage Manager…that is optional and not even nice to look at…with bad reactions on this forum….will be almost universally ignored because most users don’t even know…
…command-tab.
