Upgraded to Yosimite 10.10.5 and found out to my surprise the 5D3 is not supported. I'm wondering about going back to Mavericks or up grading to El Capitan. Anyone know about this?

In El Capitan?Version 29.1a of the software should work with your camera.
I think that was Yosemite, but if you go to the Canon software page for those EOS tools there is a selector for your OS and it looked like everything was now supported. Verify though for sure. http://www.canon.co.uk/support/cons...wnload&language=EN&os=OS X 10.11 (El Capitan)
You should probably just update your software.... Never had issues with 5D3 and the new OS.
