If you want to delete in spite of everything this warnings, You can change it at your own risk the mysql_safe script : comment the complete condition “nohup nice > /dev/null 2>&1″ and insert after this instruction : NOHUP_NICENESS=”"

@wpicz, this is only true if you’ve upgraded to a later version by compiling from source. The file /usr/local/mysql/bin/mysqld is not touched after updating.

The mysqld program referenced in the mysqld_safe script is located in /usr/local/mysql/libexec/ which is updated.

If you run /usr/local/mysql/bin/mysqld then you will not start the latest version you compiled. I don’t understand why ? all seems ok :

mysql> \s
————–
mysql Ver 14.14 Distrib 5.1.45, for apple-darwin10.3.0 (i386) using readline 5.1

@wpicz, I also get the warnings but MySQL still runs properly after restarting the machine or killing mysql. If you run /usr/local/mysql/bin/mysqld then you will not start the latest version you compiled.

I found some warnings with the mysqld_safe script :
com.apple.launchd[1] (0x1001074d0.anonymous.nohup[2244]) Bug: launchd_core_logic.c:8301 (24003):0

com.apple.launchd[1] (0x100416fe0.anonymous.nohup[2245]) _vprocmgr_switch_to_session(): kr = 0x44c

To resolve it, I launch mysqld directly :

Label
com.diymacserver.mysql
Program
/usr/local/mysql/bin/mysqld
ProgramArguments

–user=_mysql

RunAtLoad

KeepAlive

UserName
_mysql
GroupName
_mysql
Umask
7
WorkingDirectory
/usr/local/mysql

If this can help somebody…
