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).

You're highly likely to meet issues with your 1st choice due to CPU and graphics model. 2nd choice is far better as the underlying hardware is more likely to be compatible with OS X. Snow Leopard will not support Haswell platforms though, it only goes up to Sandy Bridge (possibly Ivy Bridge) generation and with 10.6.8. It's just too old now (it does kind of look a little dated today) and Apple dropped all support a year ago. Mavericks or Yosemite is your best choice.

There you go! Now you just have to tidy the installation to add support for things that may not be working such as audio or LAN...

Sorry, no support for any TMX stuff here. You know where to go for that... I strongly suggest you use myHack v3.1.2 to install SL. myHack provides the facility to easily install/remove kexts in/from /Extra/Extensions, leaving all Vanilla kexts untouched in /S/L/E. To boot in 32bit mode, you need to use the bootloader option arch=i386.

You had the kexts before, you listed them in your previous posts. Don't use EDP, it appears you'll screw up your D830 again.

To get rid of NullCPUPowerManagement, simply remove it from /Extra/Extensions and run myFix (quick) as suggested and confirmed in posts #21 and #22. You can also try my edited DSDT by placing it in /Extra under the name of say DSDT_new.aml. You can then safely test it by calling on the file at bootloader prompt by typing: DSDT=/Extra/DSDT_new.aml. Once you're happy that it works, you can delete the old one and rename the new one into DSDT.aml. The DSDT will most defintely fix your black screen issue. I don't know what you were trying re: audio but it's a simple matter of using VoodooHDA + AppleHDADisabler kexts. You had them initially, there was nothing wrong there. If you can only boot into safe mode, you won't be able to run myHack/myFix app. However, you can manuall call myFix from Terminal using the command myfix -qt /.

No reason why your graphics would be limited to that resolution; I guess you may not have full graphics acceleration... What graphics do you have? If Intel GMA X3100, make sure to run SL in 32bit mode. To update to 10.6.8, just download the Combo update off Apple's web site. There are no horror stories that I'm aware of. Audio and Ethernet should work with VoodooHDA + Broadcom 5722D, assuming this has same hardware as D Series. Post your specs as displayed by Terminal command lspci -nn (needs lspcidrv kext installed and loaded).

There you are. This is a fully complete pack (up to 10.6.8), i.e. no need of EDP. It has everything you need to support all your hardware. Install with myHack v3.1.2 or manually replace your /Extra folder with the attached to rebuild your setup. D430_SL_pack.zip

Wrong section! This is a myHack sub-forum... Please move your post to the AMD support section. Thanks.

myHack v3.1.2 is what you need for SL. Your issue is not myHack-related, it's more likely something to do with the bootpack. What do you have in that Inspiron 1520. Should be a C2D on what I believe to be an Intel 965GM chipset, so a close cousin of the good old D630 and D830. Try and post a picture of the Kernel Panic or of that screen when the system fails.

Why do you use NullCPUPowerManagement? That defeats the purpose of having P&C States activated in your boot plist, the MBP5,1 profile and the tune FakeSMC... Get rid of it. In addition, on checking your DSDT, it turns out it has an incorrect configuration of the GPU section... Where did you get this DSDT? Here's a correct version: DSDT_D830_NVS-140M.aml.zip

Mobile Intel HD 4600 is not natively supported at all in Yosemite; however, once the Intel HD kexts are patched (dev id injection in plist + binmod of kext binaries), everything is Ok and there is no need to actually inject/use the desktop Intel HD 4600 id 0x0412 anymore. I'm interested in all those other patches you mentioned, they're probably applicable to the E6440 too as several little features do not work (Ctrl-F1 for Sleep, Audio jack, etc). What do they all individually do?
