OK, some more news on this. It has definitely an Adobe Component (=Plugin won't work with Safari 5.1 and Lion), but more importantly, an Apple component (Safari 5.1 with Lion will download PDFs instead of displaying them inline).


The Schubert Plugin creates more problems than it solves: a) it slows things down considerably b) it has a tendency to crash on scrolling pages and c) it works strictly within Safari.


What wasn't mentioned is that across OS X, the web rendering engine for PDF's is also called for by other applications, in my case, most notably, Filemaker Pro 11. When a filemaker Page displayed inline PDFs in a web portal just fine unter Snow Leopard, the entire Filemaker crashes ANY time a portal calls a PDF file - and it crashed not just the web portal, but the entire filemaker application!


This is beyond annoying, it has cost me money, and no one seems to be able to solve this. I have had this problem for over a month, and I have no idea where to turn.


I am convinced Apple has the most advanved OS available today. But that doesn't justify ignoring obvious bugs on Apple's end - get it fixed, now. It's as easy as rendering PDFs in Safari again.

I couldn't agree more. Both Apple and Adobe should fix this ASAP. It has cost our organization also a lot of money and resources (offering support, redeveloping parts of our software). It is such an obvious bug, that it should have turned up during the beta-testing period. I hold Adobe partialy responsible, but it's common knowledge that they are crappy at testing new OS versions. From Apple I did'nt expect this.


I hope those tech guys at Apple read this thread; please FIX THIS ASAP!

Good news, in the latest nightly build of WebKit (the Safari core) they fixed this issue. Only downside is that the zoom, download and previous/next page buttons aren't visible yet, so zooming into a PDF or downloading it when it's embedded doesn't work. I assume that this will be available when Apple releases 10.7.2 (probably later today).

Thank you lvschie for your factual knowledge and follow up of this issue, very helpful to me as a student who can't access scholarly info online for the numerous projects due. (I use FireFox to download PDF's to my Mac, which is less than ideal.)


Keeping my fingers crossed on a 10.7.2 or Safari update to fix this.

Nope, Apple is the only one who can offer a solution, since they've decided to remove the support for embedding PDF's in Safari 5.1 through the EMBED and OBJECT tags. Or maybe Adobe, but they've yet to release a new PDF plugin that is supported by Safari 5.1. But with the speed Adobe releases fixes for their software, I wouldn't get my hopes up that they will come up with a working plugin any time soon.


Edit: There's a nice article on the Adobe part on ZDNet;

Just to offer a different viewpoint:

That is a pdf from Canon's website, in Safari 5.1.1, no plug ins of any kind installed so I am not sure why you are getting the results you are.


You do not need plugins to view pdf's in Safari 5.1.1

I do hope that it is fixed in 5.1.1, but that canon pdf doesn't look to be displayed using embed or object (or iframe, the other way that was a problem), so it doesn't prove anything yet. Direct-link pdf's haven't been any trouble, save for those with adobe pdf plugins that don't work with 5.1

I just am developing a FM Pro 11 solution involving a web portal displaying pdfs. Works fine under Snow Leopard as long as the pdf was not compressed using Adobe Acrobat. I have a 1.5MB pdf which displays fine in web portal in FM but crashes FM if I try to optimize in Acrobat to reduce file size. So maybe it depends on the format of your pdfs. Not all pdfs are created equally apparently!

This is DEFINITELY NOT FIXED, and is a huge pain. As per this thread I've installed the latest java, Firefox, and Adobe products and plugins, and latest updates to Lion. Safari 5.1.3. OSx 10.7.3 Preview 5.5.1 Adobe Plug-ins 10.1.2 Adobe 1.1.2


Use as a common sample for testing the .pdf from the IRS http://www.irs.gov/pub/irs-pdf/f1040sd.pdf

In Firefox - The screen is blank.

To use the same example http://www.irs.gov/pub/irs-pdf/f1040sd.pdf in Safari 5.1.3 the screen is all black.

If you right click in the black area you get a pop-up window to save as or inspect element. Sure enough in the element is the embeded tag

<embed width="100%" height="100%" name="plugin" src="http://www.irs.gov/pub/irs-pdf/f1040sd.pdf" type="application/pdf">

When the file is saved it can then be opened by either Adobe reader or Preview, but not of course Safari.


So this is a work around. When faced with a black screen from a .pdf download, right click in the black, save the file, then reopen it with preview. If you open this file in the free adobe reader on some forms you can only enter the data and print the form on others you can save both the data and the form. Using Preview seems to always save the data added to the form.


COME ON FIX THIS ADOBE or APPLE. This is a huge pain in the butt. All the files we've saved on our website in .pdf format are now unavailable to MAC users. What's the story !!!!!


Feb 12, 2012 6:37 PM in response to kpfeil

Since updating to Safari 5.1.3 I CANNOT:

Get any .pdf's:

from brokerage house for tax filing

from organizations that post minutes in .pdf

from archives of historical documents in .pdf

from government organizations that have forms and grant applications in .pdf

from my own websites that my 1,500 users depend on for current information.


This is a huge embarassment. What is going on ? I don't want to depend on Adobe Reader to render .pdf files. Browsers have always been able to render .pdf's. This destroys the functionality of millions of web pages for Mac users.


FIX IT TONIGHT !!!!
