Usually that does not work, since the clicks need to be send very fast. That is why we have the #doubleclick and #tripleclick parameters for XClick.
@wressl Workaround: Since you are on the Mac, I suggest you use XRUN together with the Mac CLICLICK command line tool. It does not have quadruple-click either, but single clicks inside a shell script might be fast enough simulate it.
If you need the X/Y coordinates as input for CLICLICK use XCLICK | where_to_click.png => now ${!imagex} and ${!imagex} are filled with the x/y value, and you can pass it to the CLICLICK command line.
