App in use message in macOS

How to fix it

The solution is to either to force the application processes to close, or remove the application in another way.

First restart the computer to see if the error message clears, and if that does not work follow the steps below.

Killing all Synergy processes

Follow these steps:

Go to the Launchpad and search for Terminal, then open the Terminal application and run these commands:

sudo killall synergy
sudo killall synergys

If that doesn't help, uninstall the Synergy application in the terminal.

Removing the .app

Follow these steps:

Go to the Launchpad and search for Terminal, then open the Terminal application and run these commands:

sudo rm -rf /Applications/Synergy.app/

This should hopefully remove the .app file (which is the application you see in the Applications folder).

Once the Synergy processes have been stopped or the .app has been removed continue with the Synergy update.
