Photoshop Actions

I recently started working on my digital art after years of absence.
I love using photoshop actions to manipulate images.
I recently downloaded one of my favorite actions Vector Sketch Photoshop Action - Cartoon Effect, and am having issues.
The action either just stops mid action or gives me error messages “The command “Oil Paint Plugin” is not currently available”
I have the latest photoshop updates installed and have followed the action author’s instructions for the action. I am using a Mac.
I had planned on purchasing more actions but if they don’t work now I don’t want to waste my money.
Any help would be greatly appreciated.

Check the item documentation, you’re probably missing something.
