Yes, you can. Here is a script, put this in a file called RunActionX-Times.jsx and copy to your Adobe Photoshop > Presets > Scripts folder. Sorry, I'm not sure where the Scripts folder is on a Mac, but you should be able to find it with no problems.

In Photoshop, your new script should appear under File > scripts. Just type in the number of times you want an action to run and VIOLA! Works like a charm!
