The best way is to add your own SMBIOS plist to your installer. Place it in /Extra for Chameleon or in EFI/... (can't remember) for Clover. Chameleon Wizard app provides a fairly substantial list of SMBIOS profiles. However CW is no longer updated since end of last year. You may use another tool called Champlist from which you can choose all sorts of Mac Model and export a SMBIOS plist file. I have used that Champlist method in the past (for MacBookAir1,1 profile) and it worked perfectly with Chameleon even though it was not available in the CW list.

You can never disable the integrated Intel HD because the nVidia GPU output is handled through the IGP. http://en.wikipedia.org/wiki/Nvidia_Optimus There are however ways to disable the discrete GPU through DSDT if required. You'll find sample configs on the web, it's been fairly largely discussed on various Hackintosh forums.

On paper, yes. Possible Optimus issue as usual.

-> Diskpart, active partition...

Support for the 8xxx/9xxx families was only introduced in Yosemite. So it's only the beginning...

Simply boot off your Win7 CD/DVD, select the FAT-prepared empty partition, format it NTFS and install Win7 on it. Leave the existing Lion partition untouched. Use Chameleon Wizard and (re)install the Boot0hfs mode as a precaution.

What's the partitioning scheme of the HDD? MBR or GPT? How were each OS installed? For instance, Lion installed on an existing MBR partitioned HDD with Win7 or Win7 installed after OS X on a GPT partitioned HDD? In which order are the partitions? OS X 1st and Win7 2nd or the other? You should be able to boot your Win7 CD/DVD in repair mode, go to DOS prompt and run the DISKPART utility to check the active partition. You may have to change the currently active partition to the other one. You should also see the Win7 NTFS partition once booted in Lion. If you don't, then it probably doesn't exist (deleted or overwritten). Example #1: D630 with 160Go HDD . GTP partitioning scheme with 1 Lion partition + 1 ML partition (both OS X Extended (journaled)) + 1 Win7 partition (NTFS) .

Try the attached. DSDT.zip Atheros AR9565 is not supported by OS X to date.

Nope sorry, I use the BT service of a factory-fitted Intel wireless card and added a 2nd natively-supported Atheros card in one of the spare 1/2 size mini-PCIe slot.

HD4600 HDMI support not sorted yet on Yosemite; that's "work in progress". Docking station, no idea, not even played with that. I'd say probably similar issues as HDMI support.

I still haven't sorted out my own headphone output so can't really help you out on that one. I've only worked on getting it silent, not throw out garbage noise with the (then inaudible) audio. USB resume on wake and Sleep on lid closure working now?

As far as I know, you can still order Mavericks from Apple and obtain a redemption code to download it. Failing that, Google is your friend...

Why don't you try Mavericks instead? https://osxlatitude.com/index.php?/topic/7091-dell-latitude-e6420-with-i5-2410m-hd3000-and-1600x900-lcd-mavericks/

USB fix is detailed in my E6440 thread; just apply the DSDT patch as detailed, i.e. add the code below to devices EHC1, EHC2 and XHC: Method (_DSM, 4, Serialized) { If (LEqual (Arg2, Zero)) { Return (Buffer (One) { 0x03 }) } Return (Package (0x0E) { "AAPL,clock-id", Buffer (One) { 0x01 }, "built-in", Buffer (One) { 0x00 }, "AAPL,current-available", 0x0834, "AAPL,current-extra", 0x0898, "AAPL,current-extra-in-sleep", 0x0640, "AAPL,device-internal", 0x02, "AAPL,max-port-current-in-sleep", 0x0834 }) DTGP (Arg0, Arg1, Arg2, Arg3, RefOf (Local0)) Return (Local0) } } To get sleep to work on lid closure, apply Rehabman's DSDT lid fixes (Lid_PWR + LidPoll). No need for the ACPIPoller kext under Yosemite, only under Mavericks. Rehabman_Lid_fixes.zip

Keep a Mavericks partition to work from. Will allow you to save the Yosemite one if it gets screwed.

Press [space] when on your Yosemite icon at the bootloader. You may have a sticking verbose flag.

Try without the SSDT file.

Not using a SSDT file already existing in a pack but in fact unsuitable to your CPU by any chance?

Tried to reset BIOS to default settings and just configure HDD to AHCI?

It's GraphicsEnabler, not graphicsenabler... the exact syntax/case matching is of outmost importance for boot options.

Same as in most OS: 'cd' command to change directory. Use 'ls' to list files. For instance: cd /Volumes/Install_OS_X_Yosemite/System/Library/Kernels ls -la Watch that target path in your 'cp' command. You write 'library' when it must be a capital 'L'...

No. But do a search on "touchscreen" and see what you get.

I know it works on some Hackintoshes, but it's not a general thing.

Re: Haswell kernel, it's not hard, no; you'll easily find the perl Terminal command to do this on the vanilla kernel or the pre-patched kernel files on the web.

Haswell platforms are supported from ML 10.8.4, not before. OS X kernel usually must be patched to run on Haswell-based laptops. If you wish to stick to SL, you simply need an older laptop (from CoreSolo/Duo/2Duo to Sandy/Ivy Bridge).
