With the public launch of OS X 10.11 "El Capitan", we will officially provide support for Photo Mechanic on this new OS. We haven't encountered any issues at all in our testing, so it should be good to go. However, as always, we would counsel caution in upgrading to a new operating system. If you have any deadlines approaching, be aware there is always a risk. Use this post to discuss any issues or questions you have with Photo Mechanic on El Capitan.
