MacOS could not be installed on your computer

The two keyboard shortcuts for sleep: Display sleep: Shift+Control+Eject Computer sleep: Command+Option+Eject

To change the default sleep mode to hibernate (in the terminal):

sudo pmset -a hibernatemode 25

I don't think there's any way to preserve the normal sleep behaviour and have a separate keyboard shortcut for hibernation without writing a script that changes to hibernate mode when called and changes it back after, somehow, but this command does work on my MBP. There's a number of options for sleep that you can see with:

man pmset

In my experience, Microsoft is investing substantial engineering, funding, resources, man and woman-power in to the Office 365 - Mac Office 2016 suite.

The updates are very rapid, easy access to pre-release and insider builds, well documented issues / workarounds.

There's even a "back channel" admin and version tracking system that helps point power users to what changes when with respect to Office for Mac.

Are there known issues - absolutely. Even better, Microsoft documents them so people don't waste time troubleshooting things. Will one or more affect you? That's harder to tell, but we have thousands of daily users in our company using these apps heavily. The number of things we need to escalate to MS are few and far between and the time to fix things is superb. I personally prefer iWork suite, but Office and Microsoft have a huge lead from what I can see for most people's needs in the office space - Mac or iOS.
