I'm not preventing sleep, but my callback does get called, at least on 10.4.8. -Marc _______________________________________________ Do not post admin requests to the list. They will be ignored.

If it's not running I use IONotificationPortGetRunLoopSource to get notified when it *does* start, and I do the KEXT related initialization then. Look at the IOKitLib documentation for this function and IOMasterPort/IOServiceMatching/IOServiceGetMatchingService etc. This email sent to site_archiver(a)lists.apple.com
