I searched for 'MySQL' in spotlight search and found 'MySQL Preferences Pane' and clicked on 'Start MySQL Server' button but the status still shows 'The MySQL Server Instance is stopped' ('stopped in red font). I also tried to install the MySQL Workbench and both new and older versions with same results. The programs seem to install just fine but afterwards they are not found in Applications folder and server setting shows 'stopped' and cannot be turned ON.
MySQL Community Server 8.0.11 using installer file 'macOS 10.13 (x86, 64-bit), DMG Archive'
