5d Mark III not downloading RAW

[pgsdeepak]

Got my 5D Mark III a couple of days back. I took a few pictures in RAW-JPEG. While I tried to download, it launches EOS Utility(latest version) and hangs. I tried the same CF card on 40D and it was able to import without problem. I tried other software like Picasa, Adobe Bridge, iPhoto, Picasa and Adobe are not able to connect to the camera. EOS Utility is able to connect and I was able to remotely control the camera and take photos. I was able to download JPEG only files as well. But when it comes to Raw, the software goes unresponsive and loses connection. Once in a while everything works fine as well (even RAW), that is the strange part

My Computer and softwares are up-to-date. Infact the 5D MIII I got through CPS Load worked fine without issues. I also made sure the CF Card and Cable are also fine. 
Is it a known problem? or should I return the camera. Thanks in advance for your response

Sorry if I got it wrong, I thought Mountain Lion was working ok with 5d MIII. All the internet search results pointed me to a raw compatibility issue which was fixed with an update. So I ruled that problem out.

the reason why I swapped the camera was, 

1. Another 5D MIII worked on my MacBook without any issues 10 days before I purchased mine (I loaned one from CPS before buying one)

2. My 40D was still working fine even when I downloaded 5D raw files using that. I could edit the raw files. Also none of the softwares were working for me (some of the internet blogs said Lightroom works even if EOS utility does not)

3. Canon Support recommended replacing the camera

Anyway, I guess I will have to live with this issue as long as I have Mac. So I will get a card reader, guess thats my only option. I dont want to return the camera again (still confusing how the 5d mIII from CPS worked, I downloaded 800+ photos in one stretch fast and the one I bought cries when I download 4-5 photos)

Like I said earlier, I am not a Mac user but my photog friends that do, tell me they have problems. And the problems are as you have described them. Very erratic, working and not working. Mostly not. I attended a class on LR 4 recently and the instructor warned us to not use Lion and LR4. That is the extent of the help I can offer.

Sorry,

Thanks ebiggs1. You and marcosf made me feel better. I had done a lot of search in the internet and could not find much luck. Atleast now I feel that I am not alone and that it is some compatibility issue with mac. Feeling relieved that the camera is fine. I will get a card reader as that sounds like the only option at this point. thanks again.

After the new firmware upgrade, all is good. I can download without issues. Before I ordered a CF card reader, i was able to do the firmware update, so saved some money as well 🙂

thanks all who took time to respond
