Another solution for the issue discribed above for MAMP Pro, as I found impossible to edit my.cnf properly :

When InnoDB is crashing, spot in the error message the DB that is causing trouble. Here it is phpmyadmin/pma__tracking so the table is the one with the pma_ extension.

Then go to /Library/Application Support/appsolute/MAMP PRO/db/mysql and remove the folder named after the problem causing DB.

Restart your MAMP server. Once you restarted with success, you can stop servers again, put back the DB folder where it belongs and start the servers again. Everything should be fine again.
