Suggestion: Paintbrush #110
Description
"Paintbrush is the original simple paint program for macOS. It provides users with a means to make simple images quickly. Accept no substitutes!
When Apple released the original Macintosh in 1984, they included two applications: MacWrite and MacPaint. Twenty-five years later, every Mac still includes a basic text editor in TextEdit, but a simple paint program is a thing of the past."
It's a very handy program and I use it on my Mac, as I really miss IrfanView here! The program is released under MIT License.
