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 actually have the problem with Preview. It uses an entire CPU and makes PDF viewing unworkable.

In another thread someone had me try this but the problem returned.

"Back up all data. Quit Preview if it's running.

Hold down the option key and select Go ▹ Library from the Finder menu bar. From the Library folder, delete the following items, if they exist:

Containers/com.apple.Preview

Group Containers/com.apple.Preview

Preferences/com.apple.Preview.LSSharedFileList.plist

Preferences/com.apple.Preview.SandboxedPersistentURLs.LSSharedFileList.plist

Saved Application State/com.apple.Preview.savedState

Log out and log back in. Launch the application and test."

i fixed the issue returning to mavericks


the issue was only with large pdf files over 400 mb.i had no issue with small pdf files


with mavericks i cannot use iCloud drive and my iPhone cannot connect with retina MBP


i have decreased my storage plan from 200 to 20 gb because i cannot use this extra gb without cloud drive.Dropbox is still working.Thanks god dropbox is not developed from apple


i liked yosemite however i must read my medical pdf files (some pdf files are more than 1,5 gb)


i am going to wait for this issue to be solved and then install yosemite.


With mavericks i never had issue with pdf files even with some pdf files larger than 3 gb(i merged some medical pdf books and created a large pdf file) preview and search are super fast!


i am disappointed nevertheless i hope that apple will address this issue.


Tim Cook was named ‘CEO of the year’!

our MacBooks cannot read pdf files however this was a great success for Tim

congratulations Tim!!!

with all these awards and interviews Tim is very busy now ,there is not enough time for him to spend for operating system and such minor things and we must respect it.The awards and the interviews are always more important!!!

a surface pro 3 can do the job

i can still play angry birds on my retina macbook pro hence i am very happy!no need to read my medical pdf files.I have bought surface pro 3 for this.

Weird! I never noticed this, but I tried one of the sample PDFs in that thread and it seems to be an issue on my machine too! Sucky!


HOWEVER I found this worked for me:

Instead of OPENING the PDF in Preview, just use the space bar to view it with Finder Quick Look. It seems to be much better, right?

Click on the full screen button to view it in full screen.

Use the up and down arrows to go between pages, or scroll wheel, touch pad or whatever.

To zoom into the PDF (change the size of the pages) hold down the option key and zoom with your mouse wheel or if you have a magic pad/macbook you can pinch-zoom.

I have this problem too and it's annoying to the nth degree. Can't get any of my work done.


Scrolling is choppy, beachball ever-returning that I have to force quit and restart to read some simple PDFs of < 2MB file sizes. What is this!?


I am working with mid-2014 rMBP with 16GB of memory that apparently I upgraded for no good reason.


I have used disk utility and also tried using the Memory Clean app. There is plenty of RAM left.


I submitted feedback to Apple as suggested.


Honestly can't say I've been truly happy with OS X upgrades since Snow Leopard. How I wish I could have thee back.
