CTRL+SHIFT+ENTER, ARRAY FORMULA EXCEL 2016 MAC. So I arrive late into the game, but maybe someone else will. This almost drove me nuts. No matter what I searched for in Google I came up empty. Whatever I tried, no solution seemed to be in sight. Switched to Excel 2016 quite some time ago and today I needed to do some array formulas. Also sitting on a MacBook Pro 15 Touch Bar 2016. Not that it really matters, but still, since the solution was published on Youtube in 2013. The reason why, for me anyway, nothing worked, is in the Mac OS, the control key by default, for me anyway, is set to manage Mission control, which, at least for me, disabled the control button in Excel. In order to enable the key to actually control functions in Excel, you need to go to System preferences > Mission Control, and disable shortcuts for Mission control. So, let's see how long this solution will last. Probably be back to square one after the coffee break. Have a good one!
