@DaFOB and @Darvinko: Thanks guys, for walking point on the update to 10.8.3. My old M4400 is purring like a kitten again....

Mick, I have my M4400 working 99%, just some known issues with recovering from sleep (black screen). I'll send my /extra to you this weekend if it can help.

I had the same thing, EDP seems to break more than it fixes. Stick to daFob and just remove the PowerMini kexts.

I don't know if you got this already, but I replaced the Wifi in my M4400 with a Dell DW1390 that worked 100% OOB.

Thanks, this seems to work a lot better! Temps stay around 50 deg.C. when idle. I think this is normal for Dell. Even better, temps go down agan after stressing CPU, never did that before (stayed at 79+ deg.). Sleepenabler works, but gives me a black screen when waking up. Any tips on that ?

I'll try that and report back....

Same here, my CPU temp goes to 79 deg. Celcius. Don't know if the GPU runs hot also.

Okay, I think I got this one worked out. Seems the version of AppleACPIPlatform.kext is wrong and not compatible with our little Dell in ML. I removed it from S/L/E , E/E and S/L/E/myhack and put an older version 1.3.6 (Google for it) in S/L/E and ran MyFix/Full. The first time it reboots there is no issue and I get to the desktop. The error in Console is gone now and my Kernel is prelinking fine, even with manual prelink in Terminal. Unfortunately subsequent boots fail with a KP. Only way to start ML is with the -f flag (so no kernel cache). Upside is that the restart/shutdown seems to be working better (99% oke) and console is clean. I put the -f in boot.plist and that does it for me. I'm happy with my 'almost perfect' Dell Hack. For who is interested, this is my workflow so far: Download bootpack from Dafob (link in post #1) with Extra and DSDT Remove voodooPowerMini.kext from /Extra in bootpack to prevent errors in ML with CPU control Make installer with MyHack and bootpack (instructions in Dafob's post) and install ML After install, delete AppleACPIPlatform.kext and replace with version 1.3.6 (see top of this post) Run MyFix-Full Put -f in org.chameleon.boot.plist in /Extra under Kernel Flags (or enter when booting in command line) Reboot Have fun !

I used the files (kexts and DSDT) posted by Dafob in the E6400 forum (E6400 in five steps), they are supposed to be compatible with the M4400. Tried myfix-full and that did not solve it.

Hi Guys, First a big thanks to all for this great site and all resources. I have my M4400 working with the E6400 guide in post https://osxlatitude.com/index.php?/topic/1764-mountain-lion-on-e6400-in-5-steps/page-0 and the /extra files. Most things work, but I can't get this fixed: 2/13/13 8:17:29.185 PM com.apple.kextcache[229]: / locked; waiting for lock. 2/13/13 8:17:33.342 PM com.apple.kextcache[228]: kxld[com.apple.driver.AppleACPIEC]: The following symbols are unresolved for this kext: 2/13/13 8:17:33.342 PM com.apple.kextcache[228]: kxld[com.apple.driver.AppleACPIEC]: _AcpiHwRead 2/13/13 8:17:33.342 PM com.apple.kextcache[228]: kxld[com.apple.driver.AppleACPIEC]: _AcpiHwWrite 2/13/13 8:17:33.349 PM com.apple.kextcache[228]: Link failed (error code 5). 2/13/13 8:17:33.349 PM com.apple.kextcache[228]: Prelink failed for com.apple.driver.AppleACPIEC; aborting prelink. 2/13/13 8:17:33.355 PM com.apple.kextcache[228]: Failed to generate prelinked kernel. 2/13/13 8:17:33.363 PM com.apple.kextcache[227]: Child process /usr/sbin/kextcache[228] exited with status 71. 2/13/13 8:17:33.363 PM com.apple.kextcache[227]: Error 107 rebuilding /System/Library/Caches/com.apple.kext.caches/Startup/kernelcache. 2/13/13 8:17:33.364 PM com.apple.kextd[12]: kextcache error while updating / (error count: 6) Tried replacing AppleACPIPlatform.kexts (1.6 and 1.3.5) but with no result other then KP's at boot. Btw I am on 10.8.2, all other things (sleep, bt, audio, wifi etc work like a charm). Any help is very welcome!
