We appreciate any and all feedback we have received on ACDSee for Mac Pro. We have been listening to you, and, over the past year, we have been building a dedicated Mac development team to address your needs. Our team has been working hard revamping the product to improve performance. Very shortly, we will be releasing a public beta version for macOS Sierra. You can help us to make it better!
Sign up to take our ACDSee Photo Studio for Mac BETA for a spin and let us know if you have any feedback. Stay tuned for more information to come.
