     I've recently been having issues with Safari reading online pdf files and loading up sites using adobe flash player.


     I've somehow tracked down a temporary solve by going into Safari's "preferences", then the security tab.

     Where it shows "internet plug-ins" I have it checked so it can load adobe flash. But when it comes to reading pdf files (adobe reader)

     I have to uncheck "internet plug ins". So in turn I can read the pdfs, but not use adobe flash player.


     There seems to be a conflict between the adobe reader and flash player that I can use both at the same time.

     Any suggestions on how to correct this issue?


     Here's a screenshot of what I have. And if I have to delete one of these plug-ins how can I do this as I don't see any options to do so.Safari Security.jpg

    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 PDF's displayed in Safari, you may be able to print by moving the cursor to the the bottom edge of the page, somewhere near the middle. A black toolbar may appear under the cursor. Click the printer 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 (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.

              Thank you, Linc Davis!

              I followed your instructions and it looks like it's working!


              I went to youtube and the adobe flash error didn't come up. Granted that I already previous had

              the internet plug-ins checked.

              Also went to a site to see if I can read any pdfs and no issue came up!
