Apple has released an update for Lion, OSX 10.7.5. This update adjusted the handling of USB devices – unfortunately crashing the ability to reliably tether with a Canon camera.
Canon is currently working on a new Software Developer Kit, slated for October release, to resolve this issue. Until then, Capture One Pro will not reliably tether to Canon cameras in OSX 10.7.5.
SOLUTION:
DO NOT update to OSX 10.7.5. Patiently wait until the new SDK is available.
- OSX 10.7.4 + Capture One Pro 6.4.4 = OK with Canon (including 5D3 and 1DX)
- OSX 10.7.5 + Capture One Pro 6.4.2 = OK with Canon (not 5D3 or 1DX)
TOO LATE?
If you have already updated to 10.7.5 and do not want to revert to the previous update of the operating system, here’s your alternative: Capture One 6.4.2 can be downloaded below, and will work realiably with Canon cameras in 10.7.5.Capture One 6.4.2 used an older version of the Canon SDK which is not affected by the changes in 10.7.5. However this older version of the SDK does not support the Canon 5D3 or Canon 1DX.
