Updating Toad to Version 1.2.0 on Mac OS Yosemite

Before you upgrade from Toad 1.0 to 1.2.0, please make sure you delete this folder first:

cd ~/Library/Containers/
rm -fR com.dell.Toad

Then install Toad 1.2.0 from App Store.
This will reset all existing connection, and you have to redo all the connection settings.

Done
