Office for Mac 2011, the current version, has been in existence for 4.5 years. That is a very long time between upgrades. But Microsoft has (finally) released Office 2016 for Mac – and it is a very good upgrade.
If you are an Office 365 subscriber, Office 2016 for Mac is part of the subscription and an easy upgrade. If you are a retail or corporate licensing client, you may have a few months until Microsoft has it available to you.
I have been fortunate to be running the beta version for the past few months and have found Office 2016 has good parity with Office 2013 for Windows (not perfect, but much, much better). The interface uses the Ribbon styling (although not all buttons and options are in the same place or available) and the functionality is near identical. The ability to move presentations between platforms has never been better (again, not perfect, but a huge step forward). This is a major undertaking by the Microsoft Mac Office team (completely coding a new version of Office) and I expect Office 365 subscribers to have a steady stream of refinements rolled out (which is great!).
