secure_file_priv ainda NULL após editar my.cnf macOS

Estou tentando ler um arquivo csv no meu banco de dados SQL, mas não consigo fazer isso por causa de problemas de segurança com o secure_file_priv. Li muitas postagens que me disseram para editar my.cnf para permitir que uma pasta seja acessada pelo SQL. Atualmente, meu my.cnf se parece com isso:

[mysqld]
secure_file_priv = /private/var/lib/mysql-files
pid-file = /usr/local/mysql/data/mysqld.local.pid

Mas, quando eu corro SHOW VARIABLES LIKE 'secure_file_priv';

Eu ainda recebo um valor NULL. Eu também reinstalei o mysql e reiniciei meu banco de dados muitas vezes. Enquanto minhas alterações no arquivo my.cnf são salvas, não há efeito na saída.

Também fiquei pensando se isso tinha algo a ver com não especificar um arquivo de configuração, mas quando eu especificava um caminho para meu arquivo my.cnf, meu servidor parava automaticamente depois que eu o iniciava.

EDIT: Adicionando conteúdo do log de erros aqui sudo tail -f /usr/local/mysql/data/mysqld.local.err:

Pelo que posso perceber, não estou vendo nenhum erro sendo registrado. Mas, quando executo o seguinte script SQL, recebo um erro.

LOAD DATA INFILE '/private/var/lib/mysql-files/table.csv'
INTO TABLE Patients
FIELDS TERMINATED BY ',' 
LINES TERMINATED BY '\n'
IGNORE 1 ROWS;

ERRO: The MySQL server is running with the --secure-file-priv option so it cannot execute this statement
