I had Adobe reader installed and I couldn't open PDFs in Safari at all. I found this fix though... (credit goes to J@ffa)
Go to Macintosh HD>Library>Internet Plugins and delete AdobePDFViewer.plugin and then quit Safari.
Now Safari 4 will use Preview to open the PDFs.
If you launch Adobe Reader (9), and check the Internet Preferences, there is a checkbox for "Open PDF in Browser using"... and a popup that shows any usable Adobe Apps installed on that machine.
UNCHECK that, Apply it, quit Safari and relaunch - bang - problem solved!
Safari now uses its internal PDF rendering.
Hello all.
I am having the same problem. I tried deleting the Adobe internet plug-in, and have also tried resetting the Adobe internet settings as described above. I've restarted Safari, even tried restarting the comp, and no luck. I've even uninstalled Adobe Reader at this point and still can't get my pdf-s to open in Safari. I know that this is a problem due to Adobe reader 9 because I had no issue until I recently installed Adobe Reader. Any other ideas??
Edit:
I've also tried reinstalling Safari, but no luck. Seems that the comp remembers all my settings anyway.
Get Safari 5.
You DO know this thread was started a year and a half ago, right? Before Safari 5 was released.
