Those commands rebuild the kext cache/prelinked kernel.

Try safe mode, adding -x flag to the above ones. Failing that, no idea... What updates did you install? I'm not aware of any 10.7.5 updates that broke a D620/D820 installation, one based on myHack at least... Maybe you'll have to re-install Lion totally.

Just boot your OS X installation through your USB installer and once you're into OS X, reinstall your Chameleon bootloader. Basically the Windows installation overwrote the boot sector; that's normal.

myHack cannot/does not/will not patch AICPUPM. In fact, you don't need a patched AICPUM kext on your CPU; the patched kext only applies to SandyBridge/IvyBridge CPUs. What you need is proper CPU power management, which you do not appear to have and won't as long as you use NullCPUPM. Tune your system through FakeSMC kext tuning + appropriate SMBIOS profile. Read this for details. Target whatever iMac profile is best suited to your system. You can use the list of available profiles provided in Chameleon Wizard app or the specs listed at everymac.com for each Mac model to help you choose. Lynnfield-based iMac models included iMac 11,1 and iMac 11,3. For iMac11,1: SMC keys=1.54f33 smc-compatible=smc-piketon You should be able to obtain native sleep/wake thereafter and without any need for SleepEnabler (which is only required if you use NullCPUPM).

USB ports availability don't just depends on DSDT (re)patching of EHCx devices to EHC1/EHC2. It also depends on the SMBIOS profile you use as that determines the USB ports # that will be supported. So please specify what you use in that respect.

No, you can't undo the update, especially if it has not fully completed, which can be the case until 1st post-update reboot has completed. Try and boot in verbose mode and without cache (i.e. boot with flags -f -v) to see if it'll boot to completion or see where it stops.

The DSDT will be the same as for previous OS X versions. For EC, you just have to check the USB devices and rename them if required to EHC1, EHC2.

No, these files are the extracted tables from BIOS; do not confuse them with patched DSDT or SSDT or even the generated SSDT required to obtain native CPU power management; they're not the same thing at all. Make sure to use files provided in a bootpack or posted in a guide.

To save the SysProfiler info, you simply open it (via AppleMenu, Alt-About This Mac or Win-About This Mac) then click on Save in File menu in the application bar...

Keyboard backlight works OOB on those Dell laptops. if you don't have backlight and no backlight control key, then you don't have the backlit keyboard. It's an optional item.

Disable hibernation and remove sleepimage file, as usual.

There are just no drivers for the GMA 4500MHD GPU because Apple never used that chip and it's not compatible with previous OS X GMA drivers (GMA950/X3100) or subsequent OS X 1st gen Intel HD drivers. There are no DSDT patch to fix anything in that respect and nothing you can do to get graphics acceleration working on your E6400. It's been looked at by many people in all directions in vain these last few years. You can still install OS X on your laptop per sé, but it'll run poorly. No version will run "fine", well at least according to my definition of the word; more like driving a limping car... Do search and read the existing Hackintosh literature on the matter, it's been extensively covered. As far as I recall, some people tried to patch X3100 drivers and kind of obtained some limited success with resolution, but it was all very inconclusive. I would not waste much time on this really if I were you, this is just not an appropriate platform as a Hackintosh. Full stop.

Please refer to the list of supported/unsupported wireless cards you consulted before. Thank you.

What about your partition scheme?

If you could tell us which OS X version your query applies to and what you've done so far, that would be a good start.

You need to partition your target disk GPT/GUID and format your target OS X partition "Mac OS X (Journaled)". This should be done through Tools->Disk Utility at the installer main screen once you've booted up your USB installer, before you proceed with actual OS installation.

Leon had explained the clock issue when dual booting in his forum blog section. The fix consists of adding a registry key in Windows. It does work, I do this all the time on my dual-boot Hackintoshes. https://osxlatitude.com/index.php?/topic/7667-fix-incorrect-clock-settings-in-windows-when-dual-booting-with-os-x-or-linux/ Regarding the "flaky" boot, make sure to rebuild your kext cache once you've booted up as your add-on kexts need to be taken into account, especially FakeSMC. This is done through Terminal using the usual commands: sudo chmod -Rf 755 /S*/L*/E* sudo chown -Rf 0:0 /S*/L*/E* sudo touch -f /S*/L*/E* sudo kextcache -Boot -U / With Chameleon/Enoch, some kexts can be loaded from /E/E but not all (like AppleHDA for instance). As such, if FakeSMC is kept in /E/E, it may not be included in the cache, hence why you would need to boot without cache to avoid system sticking on Apple logo at startup. This is typical of FakeSMC not loaded. To circumvent that issue, place FakeSMC in /S/L/E.

Well... I would not put my family jewels in the vice on it and say "squeeze!", but I guess it must be the same device and that linked product is a pretty safe buy.

Here's a 1st patched version where all I've done was: rename device GFX0 to IGPU to reflect the HD4600 integrated GPU nature inject desktop HD4600 device id (0412) inject Azul FrameBuffer #12 (0a260006), the one that normally gives full QE/CI on mobile HD4600 GPU E6540_DSDT_01.zip With this DSDT in place (you can place it in /Extra folder under the name DSDT.aml) and the attached 2 FakePCIID kexts (from Rehabman) placed in /Extra/Extensions, you should immediately gain full graphics acceleration. Make sure to remove the kext called AppleIntelFramebufferAzul.kext from /E/E, you won't need it at this stage. FakePCIID.kext.zip FakePCIID_HD4600_HD4400.kext.zip If the E6540 behaves exactly like the E6440, you will also have to remove the AppleHPET kext from /S/L/E (you may keep a backup if you wish) as that interferes with USB ports (most notably the USB3.0 ones) and internal USB devices. I also recommend you use Chameleon-Enoch r2760 as bootloader.

Ok, will start looking into it. Could you also extract your raw IOReg with a tool such as IORegistryExplorer? Just save the output file, zip it and post it. That will help me identify some of the hardware components such as SD card reader for instance.

I must have misread your 2nd post (or maybe you edited it) because I thought you had mentionned SSDT in your 1st point when I clearly see DSDT now. I've updated my response to that effect. Generally speaking, it's never a good idea to use a DSDT from a different computer model, unless the systems really are of identical specs. It may be the case for the E6440/E6540, but I would still recommend you post your raw/extracted DSDT so that I can compare. As this stage, I do not know if the specs are 100% identical even though they most probably are (LAN, audio, SD card reader, etc.). Indeed, I have listed and/or detailed the patches applied to my E6440 DSDT and if/when I made a reference to existing ones, you may of course referto the actual source to grab them from. I sure won't mind looking at your DSDT and patch it if you want... For AppleHDA, you must replace the vanilla kext in /S/L/E, so the kext provided in /E/E really is for retrieval only. You may also opt to copy the patched AppleHDA to /Library/Extensions and delete the vanilla kexts from /S/L/E.

-> Same link as provided by Jake on the 11th... Just look at the whole thread from the beginning.

1. It may, but I would recommend you extract your raw table, then patch it. 2. You may use whichever bootloader you fancy (we advocate Chameleon/Enoch + Clover here) 3. Yes, as stipulated in the guide

The D630 EC guide may also be consulted as I've detailed the installation procedure with a bit more details. If you choose Enoch in preference to Clover, make sure to use r2760 and set CsrActiveConfig parameter to 3.

Having switched to Enoch some time ago, I have now updated to r2760 which does provide some really nice and fancy features like on-the-fly kernel/AICPUPM patches that were, until now, exclusive to Clover. The devs have done some excellent work here. All versions available off InsanelyMac download area. One of the most useful parameters is the CsrActiveConfig that caters notably for kext signing and file system protection. Some details on this are available here.
