Bypass High Sierra APFS Conversion

If you install macOS High Sierra on a Mac with a SSD drive it WILL be converted to the new APFS format. However, some people do not wish to do the conversion at this time so they are waiting to install High Sierra. There is a work around using the Terminal App that allows you to install High Sierra with the HFS+ format. It is a bit technical. And, I have not tried this so have a good backup of your stuff.
