John Carter was telling about a problem with Adobe. "After allowing Adobe to install updates, I discovered I could no longer view a PDF file in Safari. I found the following fix in the Apple Support Communities: Try removing the following files:

/Library/Internet Plug-Ins/AdobePDFViewer.plugin

/Library/Internet Plug-Ins/AdobePDFViewerNPAPI.plugin

OK, John, but how do you find the Library on Mac? So, here's the info we need.

Lion reserves will NOT display Library. Snow Leopard and below lets you see it.

Regardless of what version of OS you have, the one way that works for everyone is:

1. Open Terminal (type "terminal" in Spotlight to get it)

2. At the command line, enter the following commands, one at a time. When the first command is entered, you will be asked for your login password, but not for the second command.

When you first open Terminal, the command line may look something like this:

jcarter@JC-Mac ~

$

or this:

jcarter@JC-Mac ~ $

Regardless, the command line is identified by the dollar sign. You start typing after the dollar sign.

Here are the two commands:

sudo rm -rf /Library/Internet Plug-Ins/AdobePDFViewer.plugin

sudo rm -rf /Library/Internet Plug-Ins/AdobePDFViewerNPAPI.plugin

You can copy and paste these two lines directly into Terminal (one at a time) and get the same results. Every command has to be followed by pressing the Return key.

So, there we are, thanks to John. Another question answered!
