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?

MyHack v3.3.1 carrying bugs for Snow Leopard installations; use older version v3.1.2 instead. myHack_v3.1.2.zip myHack-3.3.1.dmg.zip NB: Those versions can only be run on OS X versions up to Mavericks. They cannot be run on Yosemite and later.

Never had that problem before, so can't comment. Screen sleep is normally cancelled by mouse or keyboard, not computer sleep of course, for which you have to press the On/Off button; But you'll know that the computer has gone to sleep if the On/Off LED fades in and out.

Ok, that DSDT was not as raw as you thought... Never mind, I've cleaned it and patched it in a similar way to my E6440's. Give it a try and let us know. It injects device id 0x416 for Intel HD 4600 mobile + Azul framebuffer 0x0a260006. As such, you should also replace the Azul + HD5000 kexts I linked to earlier (there posted in my E6440 10.10.2 update). Do not inject anything through Clover now. DSDT_new.aml.zip

Well, I don't appear to be able to do anything with MaciASL, whether with v1.3 (246) or v1.3 (252), even on good DSDT such as mines from existing laptops... Your Christian's DSDT looks Ok with DSDTEditor so I'll patch that for you. Ideally, if you can boot without a (patched) DSDT file, use DSDTEditor to extract your raw table from BIOS. I don't know what Jake had patched, but I can certainly repatch the IGPU + EHC1 + EHC2 + XHC + HDEF.

Ok, I'm with 1.3 (246)... Never usually use MacIASL, I stick to DSDTEditor or the compiler/decompiler from Cham Wizard. Getting 252...

Mmm, can only recompile in ACPI 5.0 mode under MacIASL v1.3 but unable to save the file for some reason...

What's that file?

Did you replace the vanilla kernel by the Haswell-patched version or configure the ASUSCPUPM in Clover to patch the kernel on the fly?

Ok. The DSDT provided in that archive appears dodgy. I can open the file but if I try to compile it "as is", I get all sorts of errors. Can you provide a raw extracted table instead? I could not get it from your very 1st post and I think you reposted the patched version from Jake...

What's your LCD screen resolution?

If your E6540 is of close specs to my E6440, why don't you give the 10.10.2 patched files a try? https://osxlatitude.com/index.php?/topic/7387-dell-latitude-e6440-with-i5-4300m-hd4600-and-1600x900-lcd-mavericksyosemite/page-3&do=findComment&comment=47399 I've also declared the correct Azul FrameBuffer in the DSDT (0x0a260006) and stick to Intel mobile HD 4600 dev id 0x0416: Device (IGPU) { Name (_ADR, 0x00020000) Method (_DSM, 4, NotSerialized) { Store (Package (0x06) { "device-id", Buffer (0x04) { 0x16, 0x04, 0x00, 0x00 }, "AAPL,ig-platform-id", Buffer (0x04) { 0x06, 0x00, 0x26, 0x0A }, "hda-gfx", Buffer (0x0A) { "onboard-2" } }, Local0) DTGP (Arg0, Arg1, Arg2, Arg3, RefOf (Local0)) Return (Local0) } // ... }

That's what your ought to do with kexts, yes. D830n is for D830 nVidia... Just a reference really.

Your system was running fine until you did some EDP tuning, after which, it got screwed for whatever reason. With a fresh install, you'll be Ok again. EDP appears to systematically screw all D Series since the revamp of last summer, presumably because some of the critical kexts are incorrect. I strongly suggest you don't use it for the time being. I've provided you with the files required for the performance tuning, use them. The rest should be standard installation with myHack + bootpack (assuming that one is not screwed up either).

It's explained in the general guide of this site: you place all your necessary add-on kexts in /Extra/Extensions, then run myHack->myFix (quick).
