QA

Sequel Pro and MySQL connection failed

问题描述：

MySQL said: Authentication plugin 'caching_sha2_password' cannot be loaded: dlopen(/usr/local/lib/plugin/caching_sha2_password.so, 2): image not found

解决方案：

This is because Sequel Pro is not ready yet for a new kind of user login, as the error states: there is no driver. Quick fix for non-homebrew installs:

Apple Logo > System Preferences > MySQL > Initialize Database, then type your new password and select ‘Use legacy password‘

After restart you should be able to connect. Do it only on fresh installs, because you may lost your db tables otherwise.
