Does anybody know of any compatibility issues or quirks with MySQL Community Server/Workbench on macOS Sierra? I recently did an installation on a Mac that had never held MySQL
I had this same issue. I found out that the first instance you open just continues to spin when trying to run simple select statements with what seems to be no reason. You cannot even close the tab once it is open without closing all of MySQL Workbench. However, if you open up the same instance again it seems to work fine.
