This is an old bug they have had for many years and it can be very problematic for people who use keyboard that need that key a lot.
Con Scrolling in Chrome on Mac client is jittery
For some users, there is a bug which causes jittery movement on client. Scrolling on the server is normal.
Con The price seems to change constantly
Used to be free Open Source software but now prices seem to increase every few months.
Con Clicks don't get transferred to clients when the server is Windows
Bug's been open forever. Still not fixed:
Con Doesn't work with Mac (as server) with secure keyboard entry
If you use the Mac as the "server", the mouse will switch to the "client" computer but not the keyboard. Simply entering a password in Chrome on the Mac will enable the SecureEventInput and kill the ability to use the keyboard on a Synergy client. The Synergy client doesn't notify the user if this setting is enabled or not.
