Resolving installer.app malicious software error on MacOS

While I was deploying vRA 8 in my homelab recently, I ran into an issue where the installer.app could not be started due to MacOS security restrictions.

Installer.app can't be opened because Apple cannot check it for malicious software.

I ran into similar issues already earlier with other VMware product installers but never wrote down how to solve it.

Before you mount the iso file execute below command to remove the com.apple.quarantine attribute from the iso file.

1sudo xattr -r -d com.apple.quarantine  ./vra-lcm-installer-16982088.iso

Once executed mount the iso file and start the installer.app. Hopefully VMware solves this in their installers or at least adds this step in the documentation.
