Q: Bad performance with Preview
I scanned a few pages and am now working on fixing various small issues with the resulting PDF file. The file is 11 pages long, its size is 4.4MB and it's made up of non-compressed pages that were previously scanned into TIFF format.
When I scroll the file, Preview takes 100% of one CPU core and doesn't let go until I switch to another window, and it does it bad. The scrolling is not smooth and it isn't comfortable to use. It is very disappointing, because the same issues happened with Preview for OSX 10.6 on my older MacBook Pro a few years ago. This shouldn't happen on a mid-2014 MacBook Pro.
Furthermore, the Preview product doesn't get updates through the App Store, and it doesn't have a "support community" on apple.com. It looks like an abandoned product that hasn't been updated much in years, now that I come to think of it. So why deliver it at all with OSX Yosemite?
MacBook Pro, OS X Yosemite (10.10.2)
