Dear LinusI have verified the problem you were describing, and it appears that there is a bug in version 3.7.4 when processing the images to JPG on an Intel based Mac (that was the reason I didn’t see the problem in the first place) We expect to release a version 3.7.5 of Capture One on the 15th of September where this issue has been fixed.I hope you can live with this inconvenience until the release of 3.7.5, because the only real workaround I can supply you with at this time is to do the processing on a non Intel Mac (not a very practical advice).Best regards Phase One Customer Support
