When I moved to Mountain Lion (10.8.4), pdf files opened on Safari (6.0.5) would no longer download to my computer properly:  although they showed up, neither Adobe Reader nor Acrobat (even most current versions) could open them (said they were damaged).  But Firefox downloads them such that they open just fine.  I prefer the Safari browser so would appreciate it if Safari could be patched to fix this (or if someone could tell me how to fix it).

    Back up all data.


    Triple-click the line of text below on this page to select it, the copy the selected text to the Clipboard (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, remove any items that have "Adobe" or “PDF” in the name. You may be prompted for your login password. Then quit and relaunch Safari, and test.


    The "Silverlight" web plugin distributed by Microsoft can also interfere with PDF display in Safari, so you may need to remove it as well, if it's present. The same goes for a plugin called "iGetter," and perhaps others.


    If you still have the issue, repeat 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 again.

    I had a similar problem:  after the (painful) move to Mountain Lion two months ago, I had managed to make Safari download pdfs instead of displaying them, and then today, after a simple restart, Safari began to display pdfs in a separate window.

    Your solution got me back to where I wanted to be.  I have added it to the very long list of tweaks I need to make ML productive.

    I have no clue which piece of software installed those plugins behind my back.


    Thanks so much,
