Disable Adobe Acrobat Plugin in Safari

Disable Adobe Acrobat Plugin in Safari. There have been several security bugs in Adobe Acrobat in the past. Safari can view PDFs too.

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.

How to fix it

macOS 10.11 – 11.0

  1. Open “Safari” > “Preferences”
  2. 10.12-: Click the Websites button, then Internet Plug-ins: Website Settings.
  3. 10.11: Click “Security” > “Plugin-Settings…”
  4. Deselect “Acrobat Reader”
