# Downgrade MariaDB using Brew

After installing MariaDB 10.6+ I started getting errors such as:
 **ERROR 4047 (HY000) at line 10: InnoDB refuses to write tables with ROW_FORMAT=COMPRESSED or KEY_BLOCK_SIZE.** 
I needed to go back to the previous version but it was not easier to do so with brew. These are steps I have to take to downgrade it.

```shell
brew remove mariadb 
brew cleanup
launchctl unload -w ~/Library/LaunchAgents/homebrew.mxcl.mariadb.plist
rm ~/Library/LaunchAgents/homebrew.mxcl.mariadb.plist
rm -rf /usr/local/var/mysql
```

and then I reinstalled from scratch.
```shell
brew install mariadb@10.3 
```
