Today I wanted to install a fresh **vCenter Server Appliance** for further automatic provisioning with Terraform. When I wanted to install the vCenter Server Appliance I faced an error while I tried to mount **ISO** in Finder and execute the install.

This is the new feature introduced in macOS and unfortunately you have to go to **System Preferences**

<!--adsense-->

To finally open the installer click **Open Anyway**

![Open Anyway][3]

Once clicked a final question appears and we can use vCenter Server Installer opened.

Finally **vCenter Server Appliance** installer loads and you can deploy **vCSA**.

Happy installing :)
