How do I have Safari (v12) auto download PDF files On previous versions of Safari, I have been able to auto download PDF files by using the following code in Terminal:

defaults write com.apple.Safari WebKitOmitPDFSupport -bool YES


When I got a new MacBook Air running Safari 12, this option no longer works.  Does anyone know of a solution while still using Safari.  I run a lot of reports that I need to download and not just view.
The Acrobat/Reader plug-in for Apple Safari is based on Netscape Plug-In API (NPAPI), which is supported only till Safari version 11. In Safari 12, support for NPAPI plug-ins is removed, and hence the current Acrobat/Reader plug-in will not work.
