Resolving errors with MacOS Catalina Installer

[Edited with updates October 11, 2019]

UPDATE: We have notarized all our packages available for MacOS Catalina. Downloading and installing these packages should no longer cause an error.

With the release of MacOS Catalina (10.15) we have become aware of an issue with our omnibus based installers. This only affects users who upgrade to MacOS Catalina. When trying to install the Chef Workstation by double-clicking on the .pkg affected users will see an error message similar to the following:

This issue affects all products we produce a .pkg for (Chef Workstation, Chef Infra Client, etc.) but because Chef Workstation is most widely used by those running MacOS, we expect some users to encounter this error.

We are actively working on a fix. In the meantime, we have the following suggested workarounds:

1. Right-click on the  .pkg file and select  *Open With > Installer.app*
2. Installing Chef Workstation (or other products by changing the `-P` argument) using Omnitruck: 

curl -L https://omnitruck.chef.io/install.sh | sudo bash -s -- -P chef-workstation 

Both methods will allow you to install and use .pkg packages that Chef Software produces.

We apologize for this issue and thank you for your patience as we work to fix our packages!
