Hi All, I have recently changed from PC to mac and have encountered a problem with the mac corrupting the Canon CR2 RAW files. This is what I?ve worked out so far: The problem is only on the mac? The same files on the PC are all fine! The problem is random without any pattern. CR2 RAW files from both the 1Ds MarkII and 20D are affected. Files from six different CF Card are affected. Simply loading the files onto the mac seems to corrupt them. Unprocessed files are showing up as corrupted in the basic mac preview and CD/DVD?s burnt from these folders are corrupted. Adobe Photoshop CS and Adobe Lightroom Beta 3 on the mac show corrupted files. The same programs on the PC do not. I will attach an example of the problem. So does anyone know what?s happening and how to fix it? Thanks, David David Jenkins. I can't tell for sure what is going on, but I've never had that problem. How are you transfering the data to the Mac? Just a thought, are you transfering USB or Firewire? I use to have some problems when I transfered via a CF reader that was Firewire. ![]() How do I view a RAW file? The codec is only good for allowing you to see the images in preview thumbnails and open them in an image viewer. If you plan on editing your RAW files, you will need software to help you out with that. But first, make sure your computer is up to date with the latest software and codecs needed to work with RAW. When I switched to USB problems stopped. I can only share with you what I do with my Mac G5 w/ PS CS2 & my a family member's (when I visit) Dell running XP w/ PS Elements 2.0 1) Take CF out of 20D. 2) Put CF in CF Reader. 3) Create a File on Computer HD. 4) XFER all data from CF to newly created folder on Computer HD. 5) Make a CD back-up from Computer HD. It's never failed. Since 2003, I've tranferred tens of thousands of files to my Mac via a Firewire card reader from 10D, 20D and 5D without a single corruption. I'm guessing if the files are okay in camera and on a PC, you have a hardware defect. It may be as simple as a faulty USB or Firewire cable, a bad hub or bad hub power supply. I assume your other USB or FW devices are okay--no corruption of other files--so internal hardware is fine? So I'd start by by isolating the problem. Skip the card reader and hubs and plug your camera directly into the Mac to upload. If that works, you know your MAc is fine and the CF reader, cable or hub is hosed. Isolate each component and you'll soon know which one is the problem. I'm betting a cable or hub. I use MAC and OSX, Canon Raw from 1DsMk2 and 1DMk2, and 350D as well, downloading via USB2 and Firewire. I generally have no problems but I did experience a period of strange corruption of files, and it was resolved by reinstalling Photoshop (CS2) and installing the latest version of Adobe's raw conversion plugin. You might want to explore this. Failing that your Mac might be defective - the first G5 I had was duff out of the box and had to be replaced. Do you have anyone you know with a Mac who would let you download some images into it to see it the problem persists there too? Hi Guys, Thanks for all your help! Ok Ive had a go at different USB ports and directly downloading from the camera. I have also been careful to eject the card reader properly. Buy games for mac. If you’re still running a Power-PC Mac, a) it’s time to upgrade and b) this isn’t going to work. All the examples from here on out will be from my own experience installing Wine to play Guild Wars on my Mac Mini 2011. What You’ll Need First up, you’re gonna need an Intel Mac. Once you and pick a game, you’ll be ready to make sure you have what you need to run Wine. To find out what kind of Mac you have, click on the Apple menu in the upper left corner of your screen, choose About This Mac, and it will tell you. The problem does not seem to be here. One suggestion was that the corruption might be being caused during data transfer to an external hard drive (500GB firewire 800) Im using for bulk storage and back up. This was not something I had originally considered as a possible cause. I have now also tried eliminating this from the situation by only downloading files to the internal drives. Files continue to be randomly corrupt in mac preview, although strangely if you close the finder and open it again the corrupted files are then ok, seemly to have repaired themselves. As yet all the files have opened in Adobe Lightroom ok. Thanks for the advice. If I find what the exactly problem is Ill post the conclusion. Thanks David David Jenkins. System Requirements for Mac OS X FastRawViewer for Mac OS X requires any Intel-based Mac (excluding very old 2005-2006 models based on 32-bit CPUs: and ) with Mac OS X 10.6+ installed. We recommend a video card with OpenGL 2.1 support (that's every native Mac video card that works with OS X 10.6). An OpenGL emulator will be used if such a video card is not present in the system; some of the advanced features of FastRawViewer will take significant time to render without hardware support for OpenGL. For Windows FastRawViewer for Windows requires a computer with SSE3-compatible CPU (that is, manufactured after 2004) and not-so-ancient video card. It works on a variety of 32/64 bit Windows platforms: XP, Vista, 7, 8, 8.1,10 (we suggest Windows 8.1/64-bit or Windows 10/64-bit). FastRawViewer for Windows uses hardware graphics acceleration: • Graphics based on Microsoft DirectX: DirectX 9.0 is required, DirectX 9.0c support or later is recommended • Graphics based on OpenGL - requires a video card with at least OpenGL 2.1 support.
