I have been trying to log in to My Cloud Home in Big Sur 11.5.2, but it keeps asking me to click ‘Allow’ but this does not appear under the ‘system Preferences > Security & Privacy > General tab’ as directed in the login. I have deleted the app and dowloaded from the WD site and reinstalled but still the same problem. I see there are many with this problem but WD seems not bothered by this now it’s made it’s sale. I will certainly think twice before I buy another WD product!
We are sorry for this experience. Please refer to this KB article: Install WD Discovery for macOS 11 Big Sur
