If you want your terminal vim to open files you double click, follow the following steps (MacOS only):
 
1. Open Automator
2. Select Application
3. Copy the attached file
4. Save and set as default for opening files

Multiple files are opened in vim tabs.
If there is already a vim instance running, files are opened in it.
