macOS : KiCad.app file extensions : Finder.app associations

Description

Finder.app does not recognize several KiCad file extensions.

As such, KiCad files unassociated with Finder.app :

• Do not correctly sort by kind (by file extension).
• Include the extension in the highlighted text when renaming.

• Functional extension:

• Disfunctional extension:

Informal Fix

For files of an unassociated extension:

Right-click --> Get Info --> 
Open With.. --> Select [../Applications/KiCad/KiCad.app] --> Click [OK] --> 
Click [Change All..]

This will correctly associate, but it would be good to associate the unassociated extensions by default at KiCad installation.

Steps to reproduce

Sort by Kind or Rename certain KiCad files with extensions such as, but not limited to:

.bak
.kicad_sym
.kicad_mod
.kicad_sch_bak
.kicad_pri
