Open Office 4.0

I went to install Open OFfice 4.0 on my MAC and got a message that the OS did not want to allow me to run the install because the software was unsigned. I downloaded the software from a trusted site. I have used the software many times in the past (previous versions) I know how to override the block. My question is ..is there a reason that I should not install Open Office version 4 on my MAC?

No. That warning was just GateKeeper doing what it was designed to do (prevent the installation of software not signed by Apple). There's nothing wrong with OOo on OS X.

Open Office 4.0...

Thank you VanSmith.

For various reasons, some developers choose not to pay the $99/year fee to be a registered Apple developer, and thus get caught in Gatekeeper's web. If you're sure that what you're getting is legit, you can override Gatekeeper's controls temporarily -- but for the most part I strongly recommend leaving them on, as it is your best defense against malware and trickware.
