Mac OS Sierra doesn't recognize my camera...

Solved:

Older camera models dating from before 2005 used a different method of communicating with a computer. Currently most cameras use a mode called picture transfer protocol (PTP). When using PTP, a separate driver is not required to download images to your computer. When you connect the camera to a computer system and power it on in the playback mode, the system will automatically install a built-in driver. You may then download images using the built in imaging software supplied with the operating system.

In order to change the communication mode of your camera so that your newer operating system can detect the unit, please follow the steps below on your camera:

1. Press "MENU"

2. Navigate to the last set up menu (yellow section with the tools symbol)

3. Select the "COMMUNICATION" option and then press "SET"

4. Choose "PTP" and then press "SET"

5. Connect the camera to your computer

Thanks.

The procedure I explained above was given to me by a Canon representative by email for the Canon EOS 20D. After following it, my camera is now recognized by my computer in Bridge CC / Photo Downloader and in Image Capture.

You can communicate with Canon at the following address: customer_support@canada.canon.com

Best of luck,

Chris.

Do you think there is a solution?

Or do I have to buy another camera?

Thanks!

I will contact Canon, then.

Thank you all.
