Unable to install ChemBioDraw in MAC OS 10.9

Error: Unidentified developer

Solution:

Disabling Gatekeeper In Mac OS X 10:
OS X 10.8 features a new security feature called Gatekeeper which prevents the installation of malware by controlling the types of software that can be installed. At this time, many developers have not released signed versions of their applications and installers. To enable installation of these applications, Gatekeeper must be disabled at the beginning of the installation process.
Note: Gatekeeper only needs to be disabled during the initial installation and running of the application; after that, it can and should be re-enabled.
1- Navigate to System Preferences from the Apple Menu or from the Dock.
2- Click on the Security & Privacy preference pane, under the Personal header.
3- In the Security & Privacy pane, click on the Lock icon on the bottom-left.
4- Enter your Mac's username and password and click Unlock.
5- Click the radio button next to

Anywhere.

6- When prompted, click the "Allow From Anywhere" Button. You can now install any compatible application on your Mac without the installation being blocked.

Re-enabling Gatekeeper After updating any necessary software, follow the above instructions until step 5, and click the radio button next to Mac App Store and identified developers. Then close the System Preferences window.
