Maybe this explains some of the bizarre questions I've gotten from mac designers.
The other day I was explaining to one that their designs fixed width looks silly once it got up towards 4k resolutions. But the designers main concern was if people actually used full screen browsers on 4k monitors and if there was any point in thinking about the design at that resolution.
There are plenty of times I enjoy have 2 browsers side by side of even 4 browsers in a square, and being able to do that is one of the benefits of having a 4k monitor. But without a doubt the majority of my time is spent with a full size browser window open, and I observe the same from all the other windows/linux users I manage that use a 4k monitor.
In service of keeping this post simple, I've ignore system display/ui scaling. But still... the question/assumption from the mac designer completely blew my mind.
And actually typing that all out just unlocked a bunch of memories about how many times I've been:
The same process happens when I need a mac user to get to an apps settings that on a windows/linux computer would normally be under something like File > Preferences/Settings. They have no idea what I'm talking about or know just barely enough to know they don't remember how to do it and panic.Then I have to go google it and remember that CMD+comma(⌘+,) exists and reveal it to the mac user like it's actual black magic. And then I immediately forget about it until 6 months later when I need to support a mac user again and I repeat the whole cycle again.
On Mac OS Settings is located in the menu named after the program, left of File and Edit. For example Firefox > Settings.
