Hi! My MacBook Pro (early 2006 version) crashes sometimes when I try to change the display brightness. There is no message, no bluescreen - it only goes black and reboots. Mostly the problem happens on resume or when I worked a lot on the machine. It looks like a driver problem, as it happens in all apps that change the brightness. Other people have described similar problems, but there was no real solution: http://discussions.apple.com/thread.jspa?m...34 http://forums.macrumors.com/showthread.php?t=327920 Has anyone heard of that problem? Maybe there is a solution by now? Anyway, I did a bit debugging, and I found out that the brightness is changed by calling DeviceIoControl with code 0x90402444 on \Device\MacHALDriver. Is this the same way Input Remapper does it? Or is there another way to do it? As Input Remapper also requires the driver, I assume noone knows what the driver actually does, right? Cheers!
