Clear MySQL Workbench Cache on Mac

Clearing the MySQL Workbench cache means removing the rebuildable window state and, if it has grown large, the history and log files inside the app's folder. Your connections, snippets and scripts are kept in that same folder, so they are not part of the cache. The app's data usually takes 100 MB – 2 GB, so the space you recover depends on how much history and logging has built up.

What the MySQL Workbench cache holds

Specific to MySQL Workbench

The MySQL Workbench folder under Application Support holds your connections, SQL history, snippets, scripts and logs, so it contains your own data and should be left alone. Saved window positions from your last session are rebuilt automatically, and the preferences file holds app-level settings. Clearing helps when the sql_history or log folders inside that Workbench folder have grown large. If the app offers its own way to clear history or logs, use that first.

What happens after you clear MySQL Workbench

Your connections, snippets and scripts stay in place because you are only clearing the history and logs. Window positions are rebuilt the next time you open the app, so windows may not appear where they were before. Old history and log entries are gone, and new ones start building up again as you work. Deleting the app itself does not remove these folders, so your files stay until you remove them separately.

Open MySQL Workbench and check its own settings for a history or log clear option.Copy connections.xml and any snippets you need to a safe place before removing anything.Quit MySQL Workbench completely before removing any files from its folders.Reopen the app and confirm your connections are still listed.

Frequently asked questions

Yes. Folders marked “Yes, rebuilt automatically” are rebuilt automatically; removing them only makes the next start slower.

Will my saved connections still be there after I clear the cache?

Yes. Connections are stored in the MySQL Workbench folder, and clearing history and logs does not touch them.

Why don't my windows open where they were last time?

Saved window positions are rebuilt automatically, so the app may open windows in different places the first time you launch it again.
