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 got same problem on "macOS 10.12.3" installed "MySQL Workbench Community (GPL) for Mac OS X version 6.3.8 CE build 1228 (64 bit)". It's always not responding after working around I found that problem comes from MSQL Workbench is set "Default Target MySQL Version" wrong version.
Step 1: open Terminal and check your MYSQL Server version
mysql --version
My machine:
mysql Ver 14.14 Distrib 5.7.9, for osx10.9 (x86_64) using EditLine wrapper
Step 2: Open MySQL Workbench tool then go to "MYSQLWorkbench" near Apple icon on menu
Step 3: Workbench Preferences -> Modeling -> MySQL -> Default Target MySQL Version: 5.6
Step 4: Change current default from 5.6 into 5.7.9 then OK Step 5: MYSQLWorkbench -> Quit -> Open and check result.
Hope this help someone.
