Raw files are way too slow compared to Mountain Lion on quick preview.
It's something that i use on a daily basis, and today was impossible to do it... :S Spinning wheel all the time.
Anyone has the same problem?
MacBook Pro, OS X Mavericks (10.9)
With apologies for cross posting, but 'Desperate times require desperate measures' as they say...
Since upgrading to from Lion to Mavericks 10.9.1 I have this problem:. Attempts to use Preview on .rw2 (Panasonic GX7 RAW) cause massive screen corruption and virtual system hang, requiring a reboot.
Other threads may be talking about same problem, a bug in Mavericks Preview app.

As some have said, be sure to post feedback / bug report directly to Apple, not just on this forum.
Good luck

Same issue with PDF files. Preview app is now a train wreck, intermittently freezing all the time. I've noticed if you move the Preview window during a prolonged freeze, it will unfreeze it. Mavericks in general seems to have added some overhead to everything. The Launcher app has a really painful lag when horizontal scrolling.
Just as it was with iOS7, it would seem we all are not paying enough to appease the Apple gods and Mavericks is are cue to upgrade to new hardware!
Preview crashes whatever PDF file I try to open with it.
Amazing as you say that this can happen after Mavericks has been out in the field for months.
Having to use Adobe Reader instead but very annoying. Preview is such a useful tool, almost part of the OS.
No software updates yet appearing to fix the bug. Wonder how long we'll have to wait ...
Send Apple feedback. They won't answer, but at least will know there is a problem. If enough people send feedback, it may get the problem solved sooner.
Done. Hope that changes anything…
Excuse the manner of posting. I do not know how to use this self-help format. I read the summary received today of the Preview-Mavericks conflict and wanted to update my post. Others have reported this conflict as far back as October 2013. It is now January 2014. Apparently there has been no response from Apple on this issue. I will load Adobe Lightroom and Elements and no longer rely on using Apple's Preview, since Apple does not seem interested in restoring Preview to full functionality that it had under Lion. It jiust does not work any longer, since Mavericks was introduced.
I had not mentioned other Preview problems - i have had problems trying to print from Preview - formatting is often bizzarre and requires resetting features.
I believe Apple inadequately tested Mavericks with existing programs before releasing it. I am disappointed the crashes I have reported to them (which they tell you they will not respond to) did not result in some kind of announcement to this forum, that they were working on this. With the billions in profit Apple just reported for the last quarter, couldn't they invest in maintaining their reputation of being better than the pack?
I will not post here in the future as I don't need and AA or drug rehab format of self-help for matters that Apple engineers should be addressing - this is not a problem of our creation - it is Apple's baby and they should commit to correcting it. Unless this forum if full of computer engineers, we do not have the resosurces to remedy this. Thanks to all who took the time to respond. Let's hold out hope Apple will do the right thing and finally repair Preview and Mavericks.
That's it apple. After trying Mavericks for two weeks I'm going back to Snow Leopard. And not a single reply to this thread or any thread. You guys should be monitoring this like crazy all the money you make from us. This OS was simply rushed out. Basically it turned my once old but fast MAC into a dumptruck on the Autobahn.
I once was a MAC user and was happy to turn people into new MAC fans and raved about your products and their ease of operation. You've killed that enthusiasm now. Pay to ask a question online? Kill FCP7? Kill Mobile Me which is far better than iCloud? You guys have gone down the MicrosoftWormhole. Good luck to you. Time to downsize my MAC footprint already and start fishing around for other up and comers..
This is a Mac user to user forum.
You are not addressing anyone from Apple here.
We are all Mac users like you that volunteer our time to help other Mac users with their Mac technical problems.
If you want to send feedback and comments to Apple about OS X Mavericks, send your feedback here.
You won't get any responses from Apple, but they do have employees that do look at all information gathered from their various feedback links.
Well Michel as this is a technical forum, I would like to address this to all and suggest that anyone thinking of upgrading to Mavericks; does not have a 64-bit system DO NOT upgrade to Mavericks. Period.
No you will not be able to use Final Cut X, but you will not be able to use it properly anyway because your computer will run so slow. Again, based on feedback from other people, my own experiences and chatter on the internet, keep your Lion or Snow Leopard operating system and wait for Apple to start correcting what I consider a rushed to market operating system. Wait for Mavericks until you have invested in a new computer. For those with pre-64 bit laptops (or laptop pre-2012), holding off is the only sane thing to do. Upgrade to Mavericks and you will add unecessary frustration to your life. That's it. That is my preventative care tip.
All of the computer hardware requirements for Mavericks are for those Mac models that have 64 bit addressing CPUs.
Your pre-2012 Mac laptop statement is false.
To install Mavericks, you need one of these Macs:
If you are perusing Mac troubleshooting forums, the only thing you are going to see is people having issues with their Macs and OS X Mavericks. This represents only a small percentage of Mac users having major issues with Mavericks.
Millions are not having the issues you are having.
The possible reasons you are having issues is not enough RAM, low hard drive free space and/or you probably have installed third party software or third party connected hardware that is incompatible, currently, with OS X Mavericks and either "crapware", "junkware", malware that needs to be completely uninstalled or critical software that needs to be updated to Mavericks compatible versions.
My late 2009, 27 inch screen iMac runs OS X 10.9 just dandy. It runs dandy because I haven't loaded up my Mac with loads of crapware or malware, or superfluous apps, updated any software that needed Mavericks compatible updates. I have updated all of my connected device drivers to Maverick compatible versions. Plus, I have cloned backups where I can, easily, revert back to my previous OS X version and operating state if something had majorly gone wrong with my Mavericks upgrade.
Some things to consider before completely bashing OS X Mavericks.
Most users have reported here much better performance of their Macs on Mavericks once these issues were addressed and corrected.
To be honest I'm having preview problems on my both (now Mavericks) 15" MBP with maxed 16G memory and 512G SSD and 2009 Mac Pro with 32G memory and bunch of fast SSDs.
Before Mavericks upgrade both of them where working faster and more stable.
I'm very unimpresed with Mavericks and Apple inability to fix it in a reasonable time.
IMHO they would better delay it for a few more months. There where no rash to introduce it (perhaps 100% marketing).
For me Mavericks looks like MS Windows Vista
Have you tried a re-install of Mavericks?
You know, jsut because you try to write like a colelge professor, doesn't mean you're correct.
The problems with Mavericks are widespread. I have one of the proper MacPros, with 16GBs of ram, and I'm having issue after issue. I'm a professional Photographer and a MAC expert, and I've spent hours on the phoen with Apple trying to resolve the issues, to no avail.
I dont have maleware, freeware, crapware, or doucheware. I have reintalled twice.
Not sure why you feel the need to defend a clearly premature OS.
Despite of the huge inconvinience of the process I'm seriously thinking to downgrade back to previous OSX on all of my machines.
I wich I could do it for iOS7 on my iPhone and iPad since I really hate usability problems with my older eyes and how slugish both devices with iOS7.
The new minimalistic "invisible" keyboard design is really stupid. I think design never suppose to be morte important than real usability or common sense.
The reason there are so many people complaining about Mavericks is because it's a horrible mess. I don't see how it got through QA unless it was intended to make Mac products 2 years and older so slow and laggy that we'd all go running for new hardware.
My preview is seriously laggy. Chrome scrolling is way more laggy. Finder is way more laggy. Outlook 2011 more laggy. FCPX, way more laggy and crashing all the time. None of this occurred before Mavericks. Mavericks is a pig with fleas. Does Apple intend to fix any of this? Ever? If not, how do I downgrade?
Big preview problems on Mavericks
