How do I determine the default MySQL Storage Engine?

Open MAMP PRO and start the servers.
Open Terminal (/Applications/Utilities/Terminal.app).
Change to the MySQL binary directory:
```
cd /Applications/MAMP/Library/bin
```
Connect to the MySQL server:
```
./mysql --host=localhost -u root -proot
```
Select the information_schema database:
```
USE information_schema;
```
Query the storage engines:
```
SELECT * FROM engines;
```
In the result table, look for the row in the Support column with the value DEFAULT — that is the active default storage engine.
Exit the MySQL prompt:
```
exit;
```
