manta Posted January 25, 2015 Share Posted January 25, 2015 Tearing my hair out over this one, hope someone can help. My new hack (see top line of signature) boots fine 95% of the time. But randomly (mostly on cold boot or a few reboots after) it will boot extremely slowly towards the final part of the boot process and USB keyboard/mouse and other devices are unresponsive on boot for ~10 minutes. Some people get this constantly and can't boot at all (there seem to be fixes for this), but it's very intermittent in my case and I have no idea how to fix it... not good for my OCD I've tried all kinds of things to try and fix this, none of these make any difference: - keyboard/mouse in different ports - USBBusFix and related flags in chameleon - with and without DSDT for my board - disabled onboard audio and used native AppleHDA (I don't need it) - deleted Intel graphics kexts I get this stuff in the console at the final part of the boot (these lines cover 8-9 minutes, corresponding to when the USB is dead): 24/01/2015 12:48:00.823 com.apple.SecurityServer[15]: Session 100002 created 24/01/2015 12:48:05.175 com.apple.launchd[1]: (com.apple.coreservices.appleid.authentication[245]) Exit timeout elapsed (20 seconds).

Anyone have any ideas on what could be causing these problems? I've tried to include as much info as I can, if there's anything else I can provide that might help, please let me know.

manta Posted January 31, 2015 Author Share Posted January 31, 2015 After some trial/error/elimination/hair-pulling I have found that this problem seems to be related to the Pace iLok driver (USB copy protection/DRM device) and kernel cacheing. The pace driver for some reason doesn't like to be rolled in with a manual kernel cache rebuild. If I do the following steps, I seem to be able to get rid of this behaviour: 1. uninstall Pace Ilok driver (license manager/license support installer) - the installer DMG has an uninstaller 2. reboot 3. rebuild kernel cache (I use DPCImanager after repairing permissions) 4. reboot 5. install Pace driver again (license support installer dmg) I have no idea why this happens but the above is a pretty easy fix and hopefully it might help someone. If anyone has any ideas on the root causes of this I'm very curious to know your thoughts. Link to comment Share on other sites More sharing options...
