It fails here:

Follow these steps to edit the PATH file in macOS or Linux: Open Terminal through Spotlight or Applications/Utilities. Enter this command to open your Bash profile in your default text editor: touch ~/.bash_profile; open ~/.bash_profile Move the cursor to the very end of the file and enter the following, replacing folder with the path to the platform-tools folder: export PATH="$HOME/folder/bin:$PATH" Save the file and exit the text editor. Enter the following Terminal command to run your Bash profile: source ~/.bash_profile

I thought I saved the error message but I can't find it. I'll reboot and post that in the next post.
