Stuttering or Lagging When View PDF Files?

[seasurfer]

I just got my iMac Retina yesterday, I was so happy and started using it right away.

I notice that when I am reading PDF, when I try zooming in and out, it starts to lag, this does not appear on my retina MBP 2013 or my iMac 2011. Do you guys notice the same things too.

I'll assume you're on Yosemite since you're on a RiMac.

PDF viewing in Yosemite is pretty bad for larger/more complex PDF files. I have a few PDFs that were fine pre-Yosemite but are very close to unusable in Yosemite, with the same symptoms you describe.

I filed a bug report with Apple, and I sent them one of the files in question. I also saw RADAR references in the console log in one of the beta releases, which tells me they're aware of the issue (RADAR being their internal system).

If I don't see improvement in the next release, I'll open another bug report via ADP.

I don't think this is a RiMac-only issue.

I wouldn't assume it's the retina display. Adobe Reader has had long-term performance issues on OS X, even before Yosemite. This is very confusing because there are several different ways a PDF can be displayed. The most problematic is Adobe's plugin for Safari:

(1) Mac OS built-in PDF preview. Access by: selecting PDF in finder, press space bar. Page up/down by: Fn + up/down arrow keys. Result: always fast.

(2) Stand-alone Adobe Reader. Access by: double-clicking on PDF in finder (if Adobe Reader is default app for this file type). Otherwise, drag/drop PDF to Adobe Reader icon. Page up/down by: Cmd + up/down arrow. Result: relatively fast; they may have improved the performance in the latest version.

(3) Adobe Reader plug-in for Safari. Access by: open PDF from Safari, or drag/drop local PDF to Safari. Result: slow page up/down. Solution: remove Adobe plugin files and revert to Safari's built-in Adobe rendering.

I wasn't even using Adobe Reader, I didn't even install it. I was using Preview, and it is really laggy even for small PDF files.

I don't have this problem on my retina MBP 2013, which also uses Yosemite 10.0.0.
