Function keys not working after upgrade to Sierra

Just updated to Sierra last night. This morning the Function keys aren't working when I use my external Logitech K750-mac keyboard, however, they are working properly with the macbook internal keyboard.

Any thoughts?

Thank you,
Ken

 

Hi Ken, please follow http://kb.parallels.com/114309 and let us know if that works.

Hi Arun,

Thank you for the reply. No, sadly, it doesn't work. As I mentioned in the original post, they work from the macbook's built-in keyboard but not the external K750-mac keyboard.
Any other suggestions?

Thanks,
Ken

 

I got it working!!

I had to un-pair, then uninstall all the Logitech unifying software and then reinstall and re-pair it. Now the keys are detected in my VMs. Thanks for the assistance.

Regards,
Ken

 

I have seen the same problem reported in multiple apps. This is not a Parallels problem. Unfortunately, removing, re-installing and re-pairing did not help me. Maybe my K750 is older or has older firmware...

 

Hi @KenKnight , we are glad that your issue is resolved. Please reach us anytime for further assistance.

 

Hi @MikeS16 , did you check if there are any firmware updates for your keyboard?

 

The new Logitech software did not show any option for upgrading, so I assume it's up to date.

 

Hi @MikeS16 , please take a snapshot of your virtual machine. Action > Take snapshot and then uninstall and reinstall Parallels Tools inside your Windows virtual machine and check if that helps.

 

It's happening in Native Mac OS as well. It has nothing to do with Parallels. This is some ugly combination problem between Sierra and Logitech driver. I have a Mattias aluminum keyboard that works fine in both Mac OS Sierra and virtualized Windows. Also, my old Dell bluetooth keyboard is fine.
