Known Issue: "Installer.app is damaged and can't be opened" error when installing client on OSX Mountain Lion
Does SmartBear have a plan to sign Collaborator Client for Mac OS X so that a customer doesn't have to incur the risk of disabling Gatekeeper to install a package downloaded from the Internet?
We're currently working on getting our OSX package signed, this is somthing that you should expect to see in the next few releases. The Windows packages will also be signed.
