displaydockmacos
I have set up a two-monitor display, with my laptop on the left and my main screen on the right. I like having the Dock on the left side, but it's on the left of the left monitor, and as such it's too far to the left.
In the Dock settings, I only have the choice of Left (left side of left monitor), Bottom (bottom of left monitor), or Right (right side of right monitor). Is there any way I can set it to the left side of the right monitor?
You don't need to worry about Spaces for this. What you need to do is go into:
System Preferences --> Displays --> Arrangement
Drag the icon representing your external monitor to the top of the icon representing your macbook monitor:
You can also drag the bar representing your menubar/dock to whichever monitor you want to be your "main" display.
As far as I can find, putting the Dock on the left side of the right monitor or the right side of the left monitor can't be done.
But let's look at other possible solutions to your problem. Point #1 notes that you don't want the dock on the right because it would interfere with disk icons on the desktop. And when you first drag the Dock to the right side, it does indeed cover the disk icons on the right side. But if you select "clean up" on the Desktop once the Dock is positioned on the right, it will move those icons over to make room for the Dock. This is a temporary solution, however, because newly mounted drives will still be buried by the dock. If you select "clean up by name", however, then newly mounted drives will fit into the grid created and not be covered by the Dock.
Not the solution you were looking for, I know, but it might be a workaround.

I too have tried to have this setup, looking in display settings the closest thing that worked was this. It's not perfect but it does the job! Rearrange the left screen so that the screens meet at diagonals.
