Trouble Viewing PDF’s in Safari? Blank PDF’s in Safari | Easy Fix

I have noticed a few Mac users have come upon an issue where PDF’s do not open in Safari or that they simply appear blank.¬¨‚Ć The issue is that there is an older Adobe Acrobat plug-in NPAPI-Plug-In has been installed an is no longer supported.¬¨‚Ć Even if you install a new version of Adobe Reader this older plugin remains on the¬¨‚Ć machine and browsers like Safari will attempt to use it and the users will see a blank screen.

To Fix:  Simply close Safari and then remove the plugin.  The easy way is to use spotlight search and simply type in NPAPI,  then click on show in Finder.

show in folder

Now in the list that pops up simply delete or drag to Trash any file that shows up that has npapi and the word plugin in it.

Another way to fix is to click on the Finder Smiling face,  then click on the top of the screen and choose GO | Go to Folder

In the box that pops up, type /Library/Internet Plug-Ins


In this list that opens drag to Trash any and all files that have the characters npapi.

Screenshot of /Library/Interent Plug-Ins with older npapi plugins. Highlighted a NPAPI.plugin that needs to head to Trash.


That’s it, with these removed you can simply restart Safari Browser and PDF’s should open normally.

On a side note:  the new Firefox Version 19.0 Browser has a built in PDF viewer similar to Chrome and will open up PDF natively ignoring any plugins at all.

  1. Wow that was strange. I just wrote an very long comment but after I clicked submit my comment didn’t show up. Grrrr… well I’m not writing all
    that over again. Anyways, just wanted to say excellent blog!

  2. Problem solved – that was easy and fast.

    Thanks for explaining, in very good detail, the steps needed to fix the PDF and Safari issue.

  3. OMMMMMGGGGGGG the first option worked to just delete the plug in. Do you know how long I’ve been using two computers. I would use my desk top to view my pdf’s. now my desk top is not working so I’ve been stuck all morning till now 🙂


  4. Thanks so much – this has been bugging me and wasting a LOT of time. Really grateful to you – I just deleted the NPAPI file and it worked a dream!

  5. I’m having the same problem on iPad 3. How does one solve it on the iPad? Not sure how to access the old plug in. Any assistance is welcome.

  6. Very disappointed that it worked for everyone but me! My search for NPAPI file turned up AdobeFlashPlayer_17_a_install.dmg. I dragged it to the Trash to no effect. Is there anything else I can try?

  7. One thing I should add is that pdfs will not open in Acrobat Professional 8 (it used to but “something happened” that made it stop — I don’t know what). However, when I loaded Reader on my MacBook Air, pdfs open in Reader. Of course, Acrobat has richer features so I would prefer it opened there like it used to. Thanks!
