I have the same issue running from my Macbook Pro running macOS Mojave version 10.14.5. I can cut, copy and paste to the host but no other keyboard strokes pass through. This problem started in spring 2019 and has gotten to the point of being unusable. I am certain this is a LogMeIn client issue on the Mac. Nothing is set wrong on my machine. This has really cause a lot of issues working from home.
@SteveRingsmuth Sorry, Steve!
Could you also specify the GoToMyPC software version being run on the problem PC?
Exactly what keystrokes are you attempting to send during failure?
@SteveRingsmuth Specifically which are the functions you are trying to send through Pro to the Host PC, that are currently failing?
What OS is the remote computer(s) running?
To the best of my knowledge, any key strokes dont send. Only mouse actions. I have to type something on my mac, then copy it, then past it to the remote pc to get anything to work. This happens regardless of the Windows OS on the far end.
Just for the record, from my mac, I can do a Remote Desktop connection to another PC with the LogMeIn Client and then connect to the remote pc and all of my keyboard strokes pass through just fine, but not when I am using the client on my mac.
