MySQL 9.0 (MacOS) failed to initialize database after installation

[Simon Hiaubeng]

I had 8.3 installed before on the Mac. It was uninstalled before I install the 9.0 version.

I also deleted _mysql user from 'Directory Utility'. I don't know if this would cause any problem subsequently. I thought a new installation will re-create _mysql user in the Directory Utility, but it doesn't.

I install 9.0 using .dmg. The installation is completed successfully. The step of initializing database fails. I did this step using the utility in MacOS system preference as well as command line mysqld --initialize.

The command line gave me the clearer error:
[ERROR] [MY-013276] [Server] Failed to set datadir to '/usr/local/mysql-9.0.0-macos14-x86_64/data/' (OS errno: 13 - Permission denied)

The 'data' directory as in /usr/local/mysql/data has permission

drwxr-x--- 31 _mysql _mysql 992 Jul 14 06:13 data



What should I do? Should I change the permission for 'data' to wrxwrxwrx?

I am really a novice for database server. Please help.
