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
To finally open the installer click Open Anyway
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 :)
