I just received an email from Apple Support stating the following;
"Our records show that you may be using applications included in Logic Studio. We wanted to share some important compatibility information about these applications and macOS High Sierra, which will be available this fall. Older versions of Apple pro music applications — including applications in Logic Studio — will not launch on a computer running macOS High Sierra. New versions of Apple pro music applications — including Logic Pro X and MainStage 3 — are compatible with macOS High Sierra. You can purchase these applications on the App Store. For more information about compatibility of Apple pro applications on macOS High Sierra, please view this support article. Sincerely, Apple"
After some further research, it seems versions PRIOR to Logic Pro X v10.3.1 will not function in High Sierra AND you will have to pay to upgrade. Support website here (there are other applicable applications as well);

So take it as a warning I guess... If you don't want to purchase new software, don't upgrade to High Sierra....
