Q: Slow PDF Viewing in Yosemite

Hello,

 

Since Yosemite Beta, Safari makes viewing PDF very slow. I don't have the problem if I download the PDF and use Preview app.

 

I have a rMBP late 2013 i7 16GB. It's even slow when having a few pages open. Firefox doesn't have this problem.

 

Also it seems that randomly Safari starts to use the discrete graphics.

 

This is very very very annoying.

 

Any ideas? Or we have to wait Apple to fix this ****.. they must be pretty idle knowing how the "new" ipad is the same as before.

iPad, iOS 8.1

    I have OSX 10.10.3 and PDF scroll is sluggish on my 2014 MBP 15. But... on some zoom levels its ok! So to fix the problem I have to zoom in and zoom out several times to find the best drawing for smooth scroll. This is ridiculous.

    It is now May 13, 2015.   I am running Yosemite 10.10.3, and still this infernal PDF scrolling problem persists!  I have a $2,200 Macbook Pro Retina, and I cannot read PDF files! I tried a couple of the fixes in this thread, and it helped some:

     

       1. Select System Preferences > General > Show scroll bars > Always.

     

       2. In Preview preferences, uncheck "Use smooth text and line art".

     

    This is unacceptable!  Way to go Apple!

    The only way I can view large PDF files is with Acrobat running a VM windows in parallels. I have tried every reader imaginable, nothing else works. This has been going on for too long.

    Try to use Command+0 to zoom to 100%. This might help.

    Other zoom levels causing sluggish scroll on my MBP.

    This issue was reported on October 2014, May 2015 and still isn't fixed.

    Apparently the only fix is to not use Preview. Use a web browser or Acrobat.

    It seems to be working nice on el capitan. Big pdf files opens as fast as before.

    It does has some improvements on El Capitan, but not as good as Mavericks. Meanwhile, if a PDF contains some pictures, graphs and annotations, the performance is still bad in El Capitan. I am so doubt 'there is 8 times faster in opening PDF' which said by Apple. Maybe Apple is trying to make the time in opening PDF from 0.1 second to 0.1/8 seconds, which is nearly useless.

    Don't remember where I found this solution, but running this works for me.  I do find that I have to run it every so often (possibly after updates).  I'm on 10.10.3 and just had to run it to return speed of preview to its former self.

     

    sudo update_dyld_shared_cache -force

     

    I just updated to 10.10.4 and the slow PDF issue returned (it had been there, then gone away in 10.10.3).

     

    Running this sudo command solved the issue for me. Working fine now.  Thanks!

    I am thrilled to report that PDF viewing is finally fixed in El Capitan 10.11! I just installed the beta and it was smooth as glass. Now just don't break it again!

    Preview 8.0 seems bad in a number of ways (eg., annotation is now awful). Fortunately, if you are on Yosemite you can just download Preview 7.0. It runs fine, annotates properly, and can sit in the machine alongside 8.0 without any problems I've seen.*

    Something has gone wrong at Apple. I've just bought a new Macbook Pro with Yosemite and already I've spent hours returning the system font to something I can read (Lucida Grande), getting back the old version of Preview, and I'm now looking at downgrading Mail, if I can. Apple has made a bunch of decisions about what they think people should want, imposed much difficulty opting out of those choices, and this time they've made a lot of bad calls.

     

    * Correction: it can behave erratically when cropping. Still better than the new one, though.
