Annoying slowness of Preview after Yosemite upgrade

Something else is running on your Mac (Spotlight rebuild), anti-virus, or you are getting low on memory. I just opened a 756 page PDF (v1.6) in Preview on Yosemite and I can just flick backwards, forwards, or scroll with no pause. I am using a 2014 MBA with 4 GB of memory.

I have the same issue. The slowness creeps in when I add annotations. The more I annotate the PDF, the slower my Mac runs. This continues until I quite Preview. I have a 2013 rMBP with 8GB RAM.

I used to be able to annotate PDFs in Mavericks without this issue. Very frustrating.

As soon as I upgraded to Yosemite, the Preview viewer developed consistent problems while scrolling through PDFs. It hesitates at every page. Very annoying.

I have the very same issue, with large pdf files the app is almost unusable. Preview in Mavericks handles the same files without issues.

MacBook Pro Retina 13 Late 2013

8GB RAM 2.5GHz i5

150GB free on 256GB SSD

Please help!.

PS: with Acrobat Reader app works much better but still with a much lower performance than on Mavericks.

Let Apple now about this issue:

https://www.apple.com/feedback/macosx.html

I am writing to apple now, however I wanted to put my "one up" here as well. I have a MBP mid-2010 (core 2 duo 2.4GHz upgraded to 16Gb DDR3 and SSD) with Yosemite the visualization and scrolling of PDFs in preview is way slower and unstable.

I have noticed the same with Skim, another PDF viewer that I used to use when Preview had very limited annotation features. Same issues, it's slow and unresponsive. Adobe Reader is slightly faster than Preview now, which in really unheard of in my experience ... might this be a bug with Quartz?

it may be an issue with quarz since other pdf app relaying on the native pdf rendering show a similar behaviour (i.e. Pdf expert, and others)

Any way one car reduce the quality of the displayed PDF to gain stability and speed?

I have been looking into

defaults

com.apple.Preview

It seems to be a more generalised issue, since working on GraphPad prism (statistical software that use native pdf rendering) shows exactly the same behaviour of slow scrolling and zooming in preview mode.

Annoying slowness of Preview after Yosemite upgrade

Hopefully Apple are noticing these threads and people are sending in bug reports. I'm starting to consider running Bootcamp to work with PDFs.

I am using Parallels, in Windows VM pdf works like a charm. Since is so critical for me I am downgrading to Mavericks till fixed.

As this is a user support community - Apple does not review a incident unless someone who is working with a tech tells them about it.

So all you are having problems with any part of Yosemite upgrade should sent feedback to Apple that there are problems.

Problems that you are having may probably did not occur with Apples testing because test systems tend to have less stuff - Beta testers also may not have seen the problem -same reason == real test of a system is with the initial adopters after the system is available to everyone.

So keep sending feedback or calling support for technical issues.

My feedback has been submitted, thanks for your input.

Hopefully they will listen.

Please send them feedback as well if you have this type of problems.

Cheers,

I also use this note function very often in class. I am able to see the note, but I cannot move around the page. I am also having issues with removing a highlighted area.
