 | | | No HID events after installing security update | No HID events after installing security update 2007-05-20 - By Eric Lengyel

Hi --
I'm using HID manager to read input from the keyboard, mouse, etc., in a
game engine. Everything had been working fine for two years, but I just
installed the latest security patch from Apple (update 2007-004), and I no
longer get any events from the HID manager at all. Many of my customers are
reporting the same trouble. I strongly suspect that the problem stems from a
change made to the HID manager in this update described by the following
blurb:
http://docs.info.apple.com/article.html?artnum=305391
"Insufficient controls in the IOKit HID interface allow any logged in user
to capture console keystrokes, including passwords and other sensitive
information. This update addresses the issue by limiting HID device events
to processes belonging to the current console user."
My code basically matches the sample code on Apple's website in terms of
what functions are called and when. Anybody have any idea why I appear to be
getting hit with this security mechanism? (I'm just running an app on the
local machine.)
Thanks,
Eric Lengyel
