How to disable Adobe Acrobat PDF Reader in Safari

Open Safari, go to Preferences (under Safari on the menu bar), Security, Internet Plug-ins and Manage those plugins and see if you have a setting for Adobe Acrobat Reader. Also, from Preferences, Extensions and see if you have an extension for Reader in there.

I am also having the same problem, I went in and blocked plug-ins and it is still happening.

Try blocking the plugin as described in:Safari: About Internet plug-in management

Same for me and it all happened after the latest download of 8/3. Up until then it was fine.

Back up all data before making any changes. Please take each of the following steps until the problem is resolved.

Step 1

If Adobe Reader or Acrobat is installed, and the problem is just that you can't print or save PDF's displayed in Safari, you may be able to do so by moving the cursor to the the bottom edge of the page, somewhere near the middle. A black toolbar should appear under the cursor. Click the printer or disk icon.

Step 2

There should be a setting in its preferences of the Adobe application such as Display PDF in Browser. I don't use those applications myself, so I can't be more precise. Deselect that setting, if it's selected.

Step 3

If you get a message such as ""Adobe Reader blocked for this website," then from the Safari menu bar, select

Safari ▹ Preferences... ▹ Security

and check the box marked

Allow Plug-ins

Then click

Manage Website Settings...

and make any required changes to the security settings for the Adobe PDF plugin.

Step 4

Triple-click anywhere in the line of text below on this page to select it, the copy the selected text to the Clipboard by pressing the key combination command-C:

/Library/Internet Plug-ins

In the Finder, select

Go ▹ Go to Folder

from the menu bar, or press the key combination shift-command-G. Paste into the text box that opens by pressing command-V, then press return.

From the folder that opens, move to the Trash any items that have "Adobe" or “PDF” in the name. You may be prompted for your login password. Then quit and relaunch Safari.

Step 5

The "Silverlight" web plugin distributed by Microsoft can interfere with PDF display in Safari, so you may need to remove it, if it's present. The same goes for a plugin called "iGetter," and perhaps others—I don't have a complete list. Don't remove Silverlight if you use the "Netflix" video-streaming service.

Step 6

Do as in Step 4 with this line:

~/Library/Internet Plug-ins

If you don’t like the results of this procedure, restore the items from the backup you made before you started. Relaunch Safari.

This procedure is a diagnostic test. It makes no changes to your data.

Please triple-click anywhere in the line below on this page to select it:

ls -@Oaen /L*/In*P* | pbcopy

Copy the selected text to the Clipboard by pressing the key combination command-C.

Launch the built-in Terminal application in any of the following ways:

☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)

☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.

☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.

Paste into the Terminal window by pressing the key combination command-V. I've tested these instructions only with the Safari web browser. If you use another browser, you may have to press the return key after pasting.

Wait for a new line ending in a dollar sign ($) to appear below what you entered.

The output of the command will be automatically copied to the Clipboard. If the command produced no output, the Clipboard will be empty. Paste into a reply to this message.

The Terminal window doesn't show the output. Please don't copy anything from there.

If any personal information appears in the output, anonymize before posting.

Try this:

1. Close Safari

2. Close Acrobat

3. Command + Shift + G

4. In the "Go to the folder:" field, put in the following path: /users/[YOUR_USERNAME]/library/Internet Plug-ins/

5. Remove any of the following items present to another folder on your desktop:

- AdobePDFViewer.plugin

- AdobePDFViewerNPAPI.plugin

6. Command + Shift + G

7. In the "Go to the folder:" field, put in the following path: /library/Internet Plug-ins/

8. Remove any of the following items present to another folder on your desktop:

- AdobePDFViewer.plugin

- AdobePDFViewerNPAPI.plugin

9. Relaunch Safari

10. Go to a URL with a PDF file

You should be good now.

The Adobe plugins are where I said they are. Please review the instructions for Step 4 and try again.

There's nothing in that Folder

That's not the right folder. Please follow the instructions. Don't do something else that you think will have the same effect.
