Check your DSDT + Hibernation mode as detailed for the E6440: https://osxlatitude.com/index.php?/topic/7387-dell-latitude-e6440-with-i5-4300m-hd4600-and-1600x900-lcd-mavericksyosemite/

Please! We don't support those tools here. You know where to go... We've published some guides for this OS X version on that laptop, I suggest you read and use them.

You need to boot with NullCPUPowerManagement kext until such time as you've generated your own CPU-specific SSDT using the generator tool and be able to revert to native CPU power management.

I have just come to notice that BIOS A18 and A19 modify the System Number from -595B to -3A5B. Whilst these latest versions neither bring new particular features nor affect behaviour in OS X, they are however incompatible with unlocking passwords provided by the well-known BIOS password generator tool (Dogbert's tool included in EDP) which only supports System Numbers ending in -595B/-D35B/-2A7B. As such, if your D630 BIOS is locked with an Admin password, you're unable to unlock it if BIOS is above version A17. Please note that having a BIOS Admin password set does not prevent BIOS downgrade from Windows using the package available off Dell's support web site or directly from a USB key using the extracted .hdr file.

After verification, once updated to BIOS A18/A19, D630 laptops get a -3A5B system number trailer. With previous BIOS versions up to A17, the trailer tag is -595B. The BIOS password generator tool only supports D630 system numbers ending in -595B. In addition, unlocking passwords obtained with -595B don't work in BIOS A18/A19. You must downgrade to BIOS version no higher than A17 to be able to unlock your password. I'm now sticking to that version and I suggest everyone does the same. BIOS versions A18/A19 do not bring any new features anyway.

When you boot your USB installer, the shell path variable may not contain the link to /usr/bin where sudo exec is found. You could therefore try: /usr/bin/sudo cp -R ... or /Volumes/D830/usr/bin/sudo cp -R ... For the Chameleon boot plist, you need to use the command cat /Volumes/D830/Extra/org.chameleon.Boot.plist

The command seems to go through the tree structure; however, you have a rights issue, hence the error messages so the sudo prefix does most definitely appear required. If still not going anywhere, can you reach the /Extra/Extensions folder of your Mav HDD and list the kexts in there? Could you also use detail the contents of the Chameleon boot plist through the cat command?

If you can boot the USB installer and access Terminal, you can still make a copy of your HDD's /Extra to your USB key. From Terminal, use df command to obtain the name of the HDD Mavericks partition, then use command cp -R /Volumes//Extra /Extra_BAK. You may need to add sudo in front of the cp command. You'll then have a folder called Extra_BAK at the root of your USB installer. Zip it and post it here.

Nope, you don't need UEFI PC for Yosemite.

It just seems op forgot to attach his attachments...

In the Ukulele dmg, there are pre-defined Logitech keyboard layouts. Copy those files for UK layout to /Library/Keyboard Layout and subsequently choose the Logitech layout from the Language & Region preference panel. Go to Keyboard Preferences, then click on + button at bottom left and you'll see the desired layouts listed in Others. Select the layout and click Add. If your Windows key is not Command key, you may want to swap roles with Alt key. Go to the Keyboard prefpane, then to Modifier Keys and swap between Command and Option.

Which version of Chameleon do you currently use? Please post your compressed /Extra folder.

From Windows? Never tried that. If you don't have a Mac or a hack, I can suggest you try Nawcom's ModCD. It's an ISO image you burn to CD/DVD and it creates a bootable Snow Leopard vanilla installer. You'll need the retail SL (restored) package on another DVD or USB key.

Did you install the pack with myHack?

Chameleon... Installed with myHack v3.1.2 when you build your Snow Leopard USB installer.

Battery removal won't work on the Latitude D Series.

Failing that, the tool is available on the Net; you have to do a little search though...

I vouch for the /Extra folder packs I've posted. BIOS A09 is probably Ok as is. Make sure you've configured it as per recommended parameters.

Warning Apple's Security Update 2015-001 breaks MLPF installations. It installs: i) a new kernel v12.6.0 ii) a new System.kext v12.6.0 The security update can only be "safely" be applied on a MLPF installation if the following actions are undertaken before subsequent reboot: 1) replace new ML kernel v12.6.0 by DP1's v12.0.0 2) replace new System.kext v12.6.0 by DP1's v12.0.0 directly in /S/L/E (do not place it /E/E, it won't work) Unless those replacements are done, the MLPF installation will be unbootable. The following 3 kexts also appear to need roll-back in order to retain Bluetooth services and kextcache: 1) IOBluetoothFamily.kext (back to v4.0.8) 2) IOBluetoothHIDDriver.kext (back to v4.0.8) 3) IOSerialFamily.kext (back to v10.0.5) Whilst you're encouraged to keep a backup, the files are available below: DP1_mach_kernel.zip System.kext.zip IOBluetoothFamily.kext.zip IOBluetoothHIDDriver.kext.zip IOSerialFamily.kext.zip

You don't need a battery to update your BIOS. Download the executable package of one of the latest versions (A17 to A19) off Dell's web site and extract the .HDR file using DOS command <BIOS Filename>.exe -writehdrfile. Then, place the file on a USB key and follow the procedure to update the BIOS (power cable out, battery out, keep End key down, plug power cable, release End key after 2 seconds). This procedure has been detailed elsewhere in the forum (in D430, D6x0 or M4300 threads) and on the Net. Look up for BIOS recovery on Dell laptops. I would not use EDP if I were you (it's been causing far too many problems on older Dell laptops for too long now), stick to the initial boot pack and look for the final packs I posted here and there in D6xx section.

Guys, please, this section is for myHack installations. As this is not the case here, please move your thread to the E Series support section. Is it that difficult to have a little discipline on the forum at all?

myHack does not support Yosemite. Please post your thread in the E Series support section.

Use the attached pack. The kext goes to /Extra/Extensions, the plist files to /Extra and the HWMonitor app to /Applications. Run myFix (quick) to install the kext. You may adjust the GraphicsMode of the boot plist to your own LCD resolution if you want. D830n_tuning.zip Also ensure that IDA is not enabled in BIOS (necessary if running on a Merom CPU, which the T7800 is). In terms of kexts in /E/E, all you really should have is: AppleACPIPS2Nub.kext AppleHDADisabler.kext ApplePS2Controller.kext BCM5722D.kext FakeSMC.kext Patched_10.7_AppleRTC.kext VoodooBattery.kext VoodooHDA.kext lspcidrv.kext
