Probably two things relevant here.
One is General in system preferences which look like this:
A Magic Mouse may count as a “track pad” so if you have this setting
to automatic, the scrollers will only be shown when scrolling.
You can manually override the scroller setting:
https://developer.apple.com/documentation/appkit/nsscroller/1523591-scrollerstyle
The style it sounds like you prefer is NSScrollerStyleOverlay.
However, I would discourage you from changing this.

Hi,
I connect any non-Apple mouse, turn off the Apple mouse and the scroll
shows, in it I can´t change the background color. I used swift and
macOS. Without another mouse, only magic mouse I can change this color
without problem.

What is the mouse, and is there any installed software involved that

Hi,
I don't kown is the correct place, In a NSScroller, when I conect
the external mouse, not apple's mouse, the scroll change and show
always, the problem is that I can't change its background color. How
could it? or at least make it clear.
