Migration Assistant move from Yosemite to Sierra: keyboard and trackpad behaviour different when using Microsoft Remote Desktop I've done a Migration Assistant move of my apps/data/settings from a Yosemite machine to a Sierra machine.

After that I verified that all my "System Preferences" keyboard shortcut settings and trackpad settings had been copied over (they are; I had disabled most of them so Microsoft Remote Desktop gets all keys and mouse events)

On the Sierra machine, somehow these are note forwarded correctly:


Option-Space
Secondary-Click


With "Yosemite", both will get you the Windows "right mouse button" behaviour (firing up the context menu).

On "Sierra", this the resulting behaviour


Option-Space will get a blank space
Secondary-Click will paste the clipboard


How can I force Sierra to forward them as-sis to the Microsoft Remote Desktop session?

I'm using a "US" keyboard on both Yosemite and Sierra.

I've reproduced this issue with:


Microsoft Remote Desktop.8.0.23
Microsoft Remote Desktop.8.0.26
Microsoft Remote Desktop.8.0.29
Microsoft Remote Desktop.8.0.35
Microsoft Remote Desktop.8.0.36
It might be worth trying the latest RDC 8.2 beta from Technet :Remote Desktop Client Preview for Mac supports multiple monitors and more 

Even though it is still a beta, it offers several significant improvements over the existing release version. I've been using it for months without seeing any real issues.

Key improvements


Multiple monitor support
Copy and Paste files using Cmd or Ctrl C/X/V
Direct connectivity to desktops as well as connectivity through a Remote Desktop Gateway
A new user interface together with a redesigned user accounts experience that includes unified management
High quality video and audio streaming
Import of .rdp files into the app and export of connections as .rdp files
New features like the ability to group desktops and to copy and paste images and files
