I received my BRAND NEW 2020 M1 / Apple Silicon MacBook Air on Tuesday. Nothing was installed on it prior. I installed the WD Discovery for macOS Big Sur app, set it up, and logged in. It does not launch finder. It does not integrate into finder. it does not mount the My Cloud Home as a drive on the desktop.
The WD Discovery for macOS Big Sur app continues to work on my wife’s 2017 MacBook Air as expected.
My conclusion is that it does not work on M1 / Apple Silicon. Please fix this.
