FMS 14 only supports MySQL 5.6 Community Edition for ESS. Apple has released Mac OS X 10.11 (now 10.11.1) El Capitan and the only version of MySQL that works on it is version 5.7. I was able to get the latest Actual Technologies ODBC driver 3.3.6 to connect to MySQL 5.7 on 10.11.1 and work, but this was done on a production machine that was upgraded to El Capitan before I could say anything. So, fingers crossed. But wondering if anyone at Apple, FileMaker or Actual Technologies had posted about MySQL 5.7 working in this configuration. Obviously I feel uncomfortable about it at least until it is officially confirmed if it works. For now I'll just be watching it, but thought I'd see if anyone else ended up in this situation.
