I have been successfully replacing batteries using "Original" Apple parts on several models of A1502, A1398, A1466 MacBooks. Systems that are running macOS 11 Big Sur are now reporting a "Service Recommended" warning in the menubar after installation. Booting into older OS (High Sierra, Mojave, Catalina) do not give this error. Is there any way to rectify this issue?
