### Help with this?:Tried to use Sage's Python which was not yet installed.

My computer is a MacBook Pro (Late 2013) running macOS High Sierra. I've downloaded SageMath-8.5.app and tried to run it. I got the following error message in the sage.log file.

Unfortunately the advice in the error message seems hard to use: the directories it refers to cannot be found I have Python 3.4 installed

Any suggestions would be greatly appreciated. My expertise level is "beginner".
