Big preview problems on Mavericks

This is not a RAM problem or a processor problem, it is a Mavericks/Preview problem. When I open the same file (which is very, very small PDF) in Adobe Acrobat Pro, there are no problems.

Same here, the finder generetes the preview for .CR2 (raw files for Canon) but if you try to quicklook the file, pop up an error. And when have in one folder .dng files, finder restarts... this is annoying because if I try to copy a folder the finder randomly crashes...

Same over here > ARW files (raw from Sony A77) is very slow since Mavericks update! Can not work this way!

My question: I did email this "bug" to Apple Support > no reply. Several Apple Forums > no reply.

Why doesn't Apple answer anywhere, that they are aware of this problem and will try to fix this issue as soon as possible??

Are we not the ones paying (a lot) for there products?

Please Apple Support > do your work > and respond to our questions!

Did you file it here:

https://bugreport.apple.com/

Apple doesn't usually respond to the forums or general email. They have a dedicated place for bugs and they have responded to me within a day of my reports.

And what feedback did they give about this bug, if I may ask?

Thanks for the reply! Lets hope we get a fix soon.

Well, after getting on the phone with APPLECARE, we indexed the hard drives with SPOTLIGHT, and it's much better now

Indexing doesnt help in my case.

Same problem and very annoyng on both MBP 15" Retina (16GB) and MP with 32GB.

I'm more and more regretting that I did upgrade to Mavericks.

ML was way more stable and better working.

Apple shouldve test it for a few more months before going public.

One thing that worked for me was uninstalling the google drive app... after that, things is going a little bit smoother... but the previews keep going slow to open files...

Hi

I have exactly the same problem/experience with my D800 raw-files - after updating to Maverick.

Any updates on this? Such a shame. 10.8 ran very well on my MBPr. Mavericks is embarssing with RAW photos.

Same problem here with Fuji RAF files. With mountain lion everything worked perfectly!

I already tried to clear the quicklook cache, reinstalled Apple Camera RAW and Adobe Camera Raw and DNG Converter…

I have also have this problem. I too am running Preview on a MacBook Pro with 16GB ram. It is a slug. It ran fine on OS Lion. Since updating to Mavericks, it appears something changed. I now notice a blue drop down box flashing down and up, hard to read. It locks up preview and will not allow viewing or allow me to quit Preview. It appears to be trying to index images on any memory card plugged into the Mac.

I can no longer quickly inspect memory cards for contents before deciding whether to delete the contents. I also have Sony format raw and jpeg images, and all Apple updates to date.

I have resorted to using Force Quiit to get out of Preview which, with Mavericks, seems to be extremely flawed (unless this is another attempt to eliminate privacy by collecting everything ever loaded on a computer, in which case you can report to the NSA it is working fine....).

Serously, I hope someone at Apple is monitoring this and will correct what is likely a HUGE conflict between Mavericks and Preview. This is bad for Apple's reputation, as I and others will be sharing this experience with others who have a right to know there is an unresolved problem. This has wasted several hours of my time trying to find out if it was something I had done. Apparently not, as others are also dealing with this issue.
