Finder Services - Cannot get specific service to appear/run
macOS Sierra has two built-in Terminal Services, New Terminal at Folder and New Terminal Tab at Folder.

Go to System Preferences > Keyboard > Shortcuts > Services > Files and Folders, and check one or both and add a keyboard shortcut if you’d like.

Then in Finder you can select a Folder, right-click and select the service from the Services context menu, or from the Finder > Services menu or use the keyboard shortcut if assigned.



There’s no need to use AppleScript unless you really want to.

Here's some example AppleScript code that works of me:

try
    tell application "Finder"
        set theTargetPath to quoted form of (POSIX path of (target of front window as string) as string)
    end tell
    tell application "Terminal"
        do script "pushd " &amp; theTargetPath &amp; "; clear"
        activate
    end tell
end try




Note: The example AppleScript code is just that and aside from the use of a try statement, does not employ any additional error handling and is meant only to show one of many ways accomplish a task. The onus is always upon the User to add/use appropriate error handling as needed/wanted.
