我在 mac os lion 中有 Mysql 5.6，但是当我尝试在没有 innodb 的情况下启动服务器时，即使我已将默认存储引擎设置为 myisam，它也不会让我这样做。根据文档，这应该是可以实现的。我不需要 innodb，它需要大量的 ram (>400mb) 和 cpu 负载。我试过启动 mysqld、mysql.server、launchctl。我都使用了配置文件和命令行参数。
我的 my.cnf 文件
[mysqld]
#skip-innodb
default-storage-engine=myisam
innodb=off
#query-cache-type=0
#max_user_connections=2
#innodb_buffer_pool_size = 2M
#sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES
这是输出：
2013-10-04 16:44:49 0 [Warning] TIMESTAMP with implicit DEFAULT value is deprecated. Please use --explicit_defaults_for_timestamp server option (see documentation for more details).
