Trouble with GIMP

I'm learning Python from your book and I'm finding it a great resource. However, I'm at the point where I'm creating the StickMan game and I'm having issues. I'm using an iMac running MacOS Sierra 10.12.6 The version of GIMP that I downloaded is 2.8.18. Specifically, I'm at Part III, chapter 15, "Creating the Game Elements-Preparing a Transparent Image". Steps 1 through 3 go well, but when I go to "Select -> All", there is no "All" in the "Select" menu. I am also having issues with the paintbrush as a dot. It shows up as a large square and will blot out most of the 27x30 image that I'm trying to paint. Gimp seems to be prompting me to add other layers, but I'm not clear as to how that will affect the image I'm trying to create.

I'm only using a slightly later version of GIMP than you at the moment (2.10), and I don't see any issues - though I'm not running Sierra, I doubt that makes a significant difference. For example, in terms of the Select menu, I can see All at the top:

In terms of your problem with the brush, if you look at the brushes palette, the single pixel (1x1 square) is almost at the bottom:

(Not entirely sure what you're seeing, but hopefully those screenshots help?)

Finally, regarding layers in Gimp, those aren't necessarily an issue. When you export the image (as a gif or png or anything else) it should collapse the layers into one -- and even if you find them annoying, you can click on the top layer in the layers dialog, select the Layers menu, and then click Merge Down to collapse into the next layer in the list.
