Due to camera control issues with MLA in macOS High Sierra (10.13), a public beta with a fix is now available from the Downloads page. The existing camera control setup is still available, but in this beta, a new camera control dialog is also available that will only work with cameras supported by the Image Capture framework on macOS High Sierra. It has been tested with Nikon DS5100 and Canon EOS 5D Mk2 DSLR cameras. Most Nikon DSLR cameras should work if they had before macOS High Sierra. Some Canon DSLR cameras will also work with the Image Capture framework.
As it is a beta version, thoroughly test your setup before relying on it in a time critical situation. Also ensure you have adequate backups of the show documents you are working on.
Here is also a link to download the macOS installer.
