I currently have office 2011 on my late 2013 retina MacBook Pro with 2.6ghz i5 with 8gb of ram and 512gb of storage. I am considering upgrading to office 2016 because Walmart has it on sale for the single Mac which isn't a subscription and I kind of like to stay up to date with software. For anyone who has it is it worth it? If I get it how do you completely uninstall 2011 to install 2016? If I get 2016 and install it, I would like to have 2011 completely gone off of my system. All my files that work with 2011 will work with 2016 right? Pc word documents should also be compatible just like 2011?
