私は数週間前から MAMP のインストールを行ってきましたが、今日起動したときに起動しませんでした。mysql プロセスが実行されていなかったので、サーバーの起動時に次のエラー ログを確認しました。
130826 14:19:55 mysqld_safe Starting mysqld daemon with databases from /Applications/MAMP/db/mysql
130826 14:19:55 [Warning] You have forced lower_case_table_names to 0 through a command-line option, even though your file system '/Applications/MAMP/db/mysql/' is case insensitive. This means that you can corrupt a MyISAM table by accessing it with different cases. You should consider changing lower_case_table_names to 1 or 2

したがって、特定のログ ファイルが見つからないことは明らかですが、なぜそれが起こったのか、またはそれを修正する方法はわかりません。
