I would like innodb to be the default storage engine. What do I need to do?

Answer 1

Under [mysqld] section in your ini file, add:

default-storage-engine = innodb 

It is usually /etc/my.cnf, but not sure about Mac.

From the docs:

On Unix, Linux and Mac OS X, MySQL programs read startup options from the following files, in the specified order (top items are used first).

File Name   Purpose  /etc/my.cnf          Global options /etc/mysql/my.cnf    Global options (as of MySQL 5.1.15) SYSCONFDIR/my.cnf    Global options $MYSQL_HOME/my.cnf   Server-specific options defaults-extra-file  The file specified with --defaults-extra-file=path, if any ~/.my.cnf            User-specific options 

The last one is never used by the daemon.
