Get the last version from Oracle website. As I’m writing, it’s mysql-5.7.9-rc-osx10.10-x86_64.dmg (it’s a direct download link!). Then, install from the .pkg file located in the .dmg you downloaded.
Once installed, if you try to connect to MySQL with mysql -u root -p, you’ll have this error message: ERROR 1820 (HY000): You must reset your password using ALTER USER statement before executing this statement. You need to set a new password:
SET PASSWORD = PASSWORD('my_super_complicated_password');
No more error message, but still nothing if you try to connect to your localhost with mysql -h 127.0.0.1 -u root -p or if you listen with telnet 127.0.0.1 3306. To fix that you’ll need to create a configuration file: /etc/my.conf. Here is a basic one :
[client]
port = 3306
socket = /tmp/mysql.sock
[mysqld]
bind-address = 127.0.0.1
port = 3306
socket = /tmp/mysql.sock
datadir = /usr/local/var/mysql
key_buffer_size = 16M
max_allowed_packet = 8M
log-error = /var/log/mysql/error.log
symbolic-links = 1
lower_case_table_names = 2
[mysqldump]
quick
Hope this can be help. Details about what you’re now allowed to do on MySQL Server blog.
