Possible issues related to MySQL:
- Make sure it's actually running. Try
brew services stop mysql
followed bybrew services start mysql
. - Check if it's working via the terminal first:
mysql -uroot
- If it is, and Sequel Pro is giving an error like
Authentication plugin 'caching_sha2_password' cannot be loaded
, then open up mysql in the terminal and type:ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY '';
