I had successfully installed MySQL5 in my Mac and I was able to logon to MySQL server using terminal using command:
mysql -u root -p. However, It was found out that MySQL server would not started automatically every time the system was started up.

Then I made some check by following the ReadMe file of the MySQL5 installation package. I tried to run the command:
shell> sudo /Library/StartupItems/MySQLCOM/MySQLCOM start
