Hi Guys; I've used SpeedStepper to patch AppleIntelCPUPowerManagement.kext for Mac OS Snow Leopard 10.6.8 and all versions of Lion. SpeedStepper for Lion 10.7.3, applied to "AppleIntelCPUPowerManagement.kext, version 167.3.0" works with Lion 10.7.4 Before rebooting after updating Lion 10.7.3 to 10.7.4, I deleted the Lion 10.7.4 version of AppleIntelCPUPowerManagement.kext, and used an app to install the previous patched version for Lion 10.7.3. You can do this manually or use terminal, the system is still in root mode. Download for "speed_stepper_lion_1073_11d24.zip" posted here . . . http://www.insanelym...7 My system Specs . . . Motherboard: Zotac H67-ITX-C-E CPU: Intel Core i7-2600K GPU: Sapphire ATI Radeon 5770 (model 100283-3L) DSDT: Edits for HDMI audio only required, all else is vanilla WiFi: May require swapping card for an Atheros or Broadcom, or use RaLink Driver for Mac OS. All works, no issues.

That's better, thanks to 04152viki and bogdanw I was looking for the update on page one. I took the lazy route this time and used patched version 04152viki posted. And many thanks to flAked for being proactive, I see was posted in last December. SpeedStepper 10.7.3 works great for Lion 10.7.3 here ! Everything working great and a little speed boost too !

Zotac H67ITX-C-E with i7-2600K CPU BIOS Version Core: 4.6.4.0 Project: A166P 0.20 x64 Build Date: 02/28/2011 I have SpeedStepper for Lion 10.7.2 working, has been for a couple weeks. There are no issues, everything working on this system. Here's what I did to fix it (maybe do it right). It occurred to me that the problem might be the install procedure so I repeated the original steps. 1.. I did a clean install of Lion 10.7 2.. Migrated an existing install to the new install. 3.. Upgraded Lion to 10.7.2 4.. Then applied the patch. After that I only had occasional system errors. I checked the System log and found that a couple wireless printer launch daemons were looking for missing files. Removing the referenced files fixed the problems. After that I tested the printers and they worked fine. Now all's good, hope that helps others.

Zotac H67ITX-C-E with i7-2600K CPU BIOS Version Core: 4.6.4.0 Project: A166P 0.20 x64 Build Date: 02/28/2011 SpeedStepper fix works great for Lion 10.7.1 to eliminate NullCPUPowerManagement. Doing so enabled power button and power dialog sleep, and wake from sleep also works. The power button blinks while in sleep mode. Lion 10.7.2 crashes on the way down on restart or shutdown, no error messages, just the kill with power button message. Tried downgrading to patched AppleIntelCPUPowerManagement for Lion 10.7.1 but same issue. Tried DSDT fixes and dozens of other related things but nothing works. There were no other issues, I used the system for a day. It booted fine, restart and shutdown OK as long as I hadn't used sleep. Under both versions of Lion Energy Saver invoked sleep only gets display sleep, system does not power down. Not much of an issue since I don't use it but would be nice when the system is left unattended. The SpeedStepper fix is not needed for SpeedStep on this board, it works without it. It just eliminates the need for NullCPUPowerManagement, which is required to initially boot the system. I got a slight drop in Geekbench rating after installing SpeedStepper but nothing of any concern. My Cinebench has been as high 50 fps. It would be nice if we could have the patches as separate run files, to test which is needed and not. Or better the code to tweak as needed for non ASUS boards. This board is vanilla with a ATI Radeon HD 5770, doesn't need a DSDT except possibly for AppleHDA and HDMI audio. eSATA works too, haven't tested a RAID box but it should work. Myself and a friend also have Intel HD3000 graphics working. Cinebench is about 11 fps, which is OK for a HTPC system. Any ideas that might help get this working with Lion 10.7.2 would be appreciated. Thanks

Hi blackosx: Thank you for the AppleRTC patch fix. sudo perl -pi -e 's|\xBC\x00\x74\x10|\xBC\x00\xEB\x10|; s|\x45\xB8\x74\x08|\x45\xB8\xEB\x08|; s|\xD0\x00\x74\x13|\xD0\x00\xEB\x13|; s|\x45\xCC\x74\x0B|\x45\xCC\xEB\x0B|;' /System/Library/Extensions/AppleRTC.kext/Contents/MacOS/AppleRTC Works perfectly for Zotac H55ITX-A-E We had perfect sleep & wake from sleep in Snow Leopard, and as others reported for Lion, we had CMOS reset to defaults on a reboot after sleep. I too looked at DSDT fixes but none worked. The Zotac H55ITX-A-E community thank you.

Hi; I can't give you any specific help, the guide is a help yourself guide. Please read carefully, your questions indicate that you haven't. You can not just install the DSDT, whether the board model is A-E or C-E. Also, I will not be following posts here at IM. I posted to return the courtesy of SpeedracerX. Thanks

The Zotac H55ITX-A-E DSDT based install guide and files has been posted . . . http://www.tonymacx86.com/viewtopic.php?f=81&t=12940 It supports fully functional Snow Leopard 10.6.6 The guide includes illustrated editing and install instructions, and a vanilla and edited DSDT. It's well documented for experts and easy for newbies to follow. You might find it useful to fix any issues with this board. Thanks

The Zotac H55ITX-A-E project has moved to here . . . http://www.tonymacx86.com/viewtopic.php?f=81&t=12940 The Zotac H55ITX-A-E DSDT guide and files has been posted. The guide includes illustrated editing and install instructions, and my vanilla and edited DSDT. The BIOS of the C-E is very similar to the A-E. You should find it useful to fix any issues with C-E. Posting for the Zotac H55ITX-C-E is welcomed. Thanks

Hi; The Zotac H55ITX-A-E DSDT guide and files is posted at . . . http://www.tonymacx86.com/viewtopic.php?f=81&t=12940 The guide includes illustrated editing and install instructions, and my vanilla and edited DSDT. The DSDT and guide will also be useful for Zotac H55ITX-C-E since the BIOS is very similar. Zotac H55ITX-C-E users are invited to participate in that thread. Special thanks to SpeedracerX for sharing his DSDT to compare. You'll find information that will help resolve any outstanding issues you have been experiencing. Thanks
