Reduced number of Power features in apps of Office 365 for Mac Coming to Mac, there’s no option to leave out MS Excel (for example) if you don’t want it on your machine. That is, if you install, say Office 2016 from a USB or disk, you go to custom installation and remove all the apps you don’t want. Also missing is the ability to select apps to be installed when directly installing from Office 365 subscription page. That is to say, if you are migrating to Mac, don’t expect all apps from the Office Suite. I, for one, was disappointed as I could not open the files that I created in Microsoft Publisher on Windows 10 machine. For people who always use Publisher, it would be a turn off to find that there is no Microsoft Publisher in the Office 365 for Mac suite.
