Go to: Mac HD/Library/Internet Plugins
Trash the AdobePDFViewer.plugin and AdobePDFViewerNPAPI.plugin files
Empty the trash. Relaunch Safari
PDFs should open with no trouble.
A program I run through Safari requires the Adobe PDF Viewer plugin to be installed. When I upgraded my Safari to 5.1.7 (which a program I used requires) the dobe Acrobat NPAPI Plug-in, Version 10.1.4 shows as installed, but the AdobePDFViewer.plugin is not recognized by Safari.
I have tried re-installing Adobe XI to see if the PDFViewer.plugin installs, and it does not. When I revert back to Adobe 10.1.4 the same is true--no PDFViewer Plugin.
I need the following:
Adobe 10.1.4 or XI
Safari 5.1.7 (not negotiable for the program that I use through Safari)
Please help, as this is work related!!
Mac OSX10.6.8 (which is the required OSX version to run said program).
All of this was working fine until somehow my Safari automatically updated to 5.1.10, which is not supported by this proram LEED Online, so I had to revert to an my Snow Leopard Disk and upgrade Safari back to 5.1.7 to be correct for this system...
Apple will continue to push the Safari update for security reasons. That won't change, and I'm pretty sure you can't disable it.
I'd have to think that LEED Online needs to update their software to bring it within four years of current standards. (OS 10.7 was released in 2010)
Nearly EVERY developer on earth that intended on doing business with Mac users beyond Snow Loepard has updated their software since 2009 when 10.6 was released.
You should also try to update/upgrade Adobe (Reader? Acrobat?) to the latest available, either 10.1.9 or 11.0.6.
yes, I tried Adobe XI--which is supposed to be compatible, but it is not recognizing the Adobe PDFViewer.plugin.
Why would Safari recognize Adobe Acrobat NPAPI Plug-in, Version 10.1.4, but not Adobe PDF Viewer.Plugin when they both are shown in my >Library>Internet Plug Ins folder?
I am wondering if at least updating this machine to Mountain Lion 10.8.2 might help fix the issue--as LEED Online states it is compatible with it:
"Mac OS X v10.8.2 "Mountain Lion": Adobe Reader version 10.1.4 & above is now supported on LEED Online on Safari 6.0.2"
