On-Screen Keyboard at the Login Window

Good morning,

We're looking at deploying a number of Mac Mini machines linked up to touchscreens for "Kiosks" where users have access to a web browser for email, but not much else.

Once logged in, the On-Screen Keyboard works very well, and we can make sure it's running all the time, however we can't get it to run over the Login Window, so the machine still requires a Keyboard and Mouse.

Does anyone know how we can get this application to run over the Login Window? I've tried getting launchd to spawn it but for some reason it gives the error that the application can't be found:

11/06/2010 09:47:24 com.apple.launchd[1] (On-Screen Keyboard[815]) posix_spawn("/System/Library/Input\ Methods/KeyboardViewer.app", ...): No such file or directory
11/06/2010 09:47:24 com.apple.launchd[1] (On-Screen Keyboard[815]) Exited with exit code: 1

wierd..

Anyway, the application has a CodeSignature section, so I can't see the loginwindow disliking it. Any thoughts?

Thanks in advance

Mac Mini, Mac OS X (10.6.3)

It's possible but the on-screen keyboard should support some pre-login limitations. Mac OS X 10.5 introduced the ability to run a launchd agent while the login screen is showing. Pre-login launchd agents are privileged programs; you must be carefully to maintain system security. For example, Typical On-Screen Keyboard for Mac OS X ( http://www.typicsoft.com/en/Products/On-Screen-Keyboard.html ) and Typical Virtual Keyboard for Mac OS X ( http://www.typicsoft.com/en/Products/Virtual-Keyboard.html ) both support the login screen. They are for Intel only. You can download it from http://www.typicsoft.com
