Edge Client for Mac customization

In APM; Customization; Advanced; Form Factor: BIG-IP Edge Client, you can change the Banner Color, Banner Text Color, Logo and Icons for the Edge Client.

When the client is downloaded and installed, the banner has a hatch pattern. This comes from BIG-IP Edge Client.app/Contents/Resources/banner_pattern.bmp on the Mac. If I simply delete this file on the Mac I get a nice clean solid background. I can also replace it with something else however what I really want to do is modify banner_pattern.bmp directly on the Big-IP so that it is part of the downloaded client. (I have done this with the Windows Edge Client by modifying /var/sam/www/webtop/public/images/my/header-transient.png and header-transient-small.png)

Would anyone know where this banner_pattern.bmp file is buried on the Big-IP – I can’t seem to find it…

Thanks
