Mac will not work with Canon EOS cameras

Question

Mac will not work with Canon EOS cameras

My imac OS X 10.6 is not working well with my Canon EOS 5d Mark II camera on the tethered mode. The camera works well with other Mac computers, and I have spent hours with Canon tech help. It now seems that the issue may be with the computer. The EOS Utility is working, everything has been updated, all Canon checkpoints look good, but when I use the camera, the image does not transfer. And then everything gets locked into a loop and I have to crash the camera and force quit the program. Is there something in the computer that may be blocking the transfers? any ideas where to look? Canon has done everything on the camera side, but I don't know where to begin with the computer.

iMac, Mac OS X (10.6.4)

Have you tried other cameras on your mac? change usb cables and use a different port and see if anything changes. If not run an apple hardware test and see if you are having a problem with the usb ports on your logicboard.

Thanks. All cameras work with other computers, no camera works with this computer. The USB port seems fine, external drives do well with them. The Mac system hardware info shows no issues. I'm still trying to figure if Apple has a "permission" issue.

Can it pick up that the camera is there at all? for example do Aperture/Lightroom photo imports work?

If the answer to both of those is "no" then you will want to reinstall the OS and before you install anything plugin the camera and see if it gets seen. If not, then take it to get fixed.

When I open EOS Utility and tether the camera, the computer recognizes the camera. When I hit the shutter via the computer, the camera works, but the transfer is never completed. It hangs up both the camera and computer. Canon tech spent a lot of time with me running senerios and everything seems to be good except to the last point.

OH, ok. So the issue is with transferring the image from the camera to the computer. Since you said you have done everything possible with canon, the camera's firmware is completely up to date, you have the correct software installed. Since you say no cameras work with this computer I am inclined to say the problem is from the computer, which is why the problem exists. I'd do an apple hardware test and see if anything turns up. Clean install of the canon software would also be a good idea.

Hi Victoria and welcome to Apple Discussions,

As a temporary fix if you need the pictures urgently get a USB card reader and take the card from the camera and get the pictures on the computer that way.

Happy Christmas,

Alan
