  • What do you see when you cmd shift 4 and selected the region? Commented Apr 26, 2011 at 18:21

  • Is Aqua window manager still running or are you in a non-default X11 mode different than simply firing up the standard X11.app after a normal user log in to OS X?

  • @bmike I don't know what you mean by Aqua windows manager, if you mean the X111 grey windows, yes it runs and wireshark run within it.

Click to the desktop or any other application, and then press + + 3.

With this method Wireshark will loose the focus and you can grab the whole screen.

  • there is no desktop when you cmd+tab to wireshark you go to another envirinment (X11) and if you want click desktop must switch to another application then your solution is useless for my case.

  • Not true, resize your wireshark window to have a little smaller and then you can click on the desktop, or use Expose to show the desktop click on it and use Expose to show your application again. I did it and it worked. Commented Apr 26, 2011 at 20:32
  • I don't know how you can do it because when I want run wireshark first it rum X11 (a grey environment) then run wireshark into X11 so when I minimize or resize wireshark I just see X11 Grey environment and can't resize it (or minimize)

  • On the download page you can download Wireshark images for OSX which starts X11 automatically and runs almost like a normal application. Commented Apr 26, 2011 at 21:36

    If you're seeing "a grey environment" whenever X11 starts up, then X11.app is running in full screen mode. Press Cmd-Opt-A to toggle that, then you should see Wireshark running as a regular window on your desktop, and the other screen grabbing suggestions here should work fine.

Have you tried using Grab.app? It supports a "timed screen" capture mode. You'd switch to Grab.app, select "Timed Screen..." then switch back to X11. After 10 seconds it will do a screenshot.


According to @calum-benson's hint, I found what my problem was. I must un-check 1Full-screen mode1 in X11 Preferences.
