Microsoft has confirmed that the last two editions of Office for Mac are compatible with OS X Mountain Lion.
Apple launched OS X Mountain Lion yesterday. It is being delivered through the Mac App Store.
Microsoft said that users would have to run the Microsoft AutoUpdate app to download some patches which are needed for the compatibility.
The company added:
Mountain Lion ships with a new feature called Gatekeeper. Gatekeeper helps protect users by allowing you to choose to only download and install software from known developers, like Microsoft. Please note that due to the Gatekeeper architecture, updates will not run when you download and initiate them on your desktop; instead please use Microsoft AutoUpdate to keep your copies of Office for Mac current.
