cool, I don't need HDMI audio but definitely internal audio. any experience with I2C touchpads around here? That's what I'm most concerned about...

Hi guys, after an extended, ultimately unsuccessful bout with my E5470 I'm thinking of getting a Latitude 5480. I know its super new and not much info but I'm trying to get a sense of how feasible that model would be for Sierra. Specs: - i7-7820HQ Quad Core - 8gb DDR4 2400 - 1tb Samsung 960 Pro NVME SSD (aftermarket replacement - Intel HD 630/Nvidia mx930 graphics - 14" FHD non-touch screen - USB 3.1/Thunderbolt 3 port - DW1560 wifi (aftermarket repalcement) - ??? ethernet - ??? realtek audio? Questions: - CPU: needs fake ID as Kaby Lake is still unsupported by macOS. From what I've read Kaby Lake generates P/C states for CPU/GPU power management automatically with appropriate SMBIOS, no need for SSDTprgen or HWP. any other info? - GPU: I'm thinking of getting the model with Nvidia GPU for doing some graphics work in windows. this would obviously need to be disabled in Sierra via DSDT/SSDT patching, is this generally doable? Intel 630HD Graphics would presumably need FakeID + DVMT set to boot then a similar skylake ig-platform ID for acceleration. anything I'm missing with that? - Trackpad: according to a chat with a Dell rep the trackpad is now I2C, so I'd need to use VoodooI2C, correct? need to investigate this further... - Keyboard: probably I2C as well? - USB 3.1/Thunderbolt 3: TB3 only available on model with dedicated GPU. I don't really need TB3 but it would be nice to have to have the USB 3.1 port working. The functionality of the TB3 port is intertwined with the Nvidia GPU so if I disable the GPU then TB3 would likely not work. I wonder if USB 3.1 would still work without the GPU... - nvme SSD: Sierra installer USB needs config.plist 10.12.3 patch from hackrnvme github repo to install OS then I'd use the hackrnvme script to generate a patched kext for SSD functionality once installed, correct? - HDMI? - ethernet? IntelMausiEthernet.kext presumably? - Wifi: will install DW1560, I already know what patches to do for that - audio: no idea, probably won't have chipset details until I buy it. anything else I'm missing? thanks again for all the help.

Looks like I spoke too soon, MacBookPro13,1 does not have correct CPU speeds for my 6820HQ. I tried using Piker's freqvectors script to change cpu vectors to MacBookPro13,3 (which matches my CPU) but this results in kernel panic (see attached pic). any idea what could cause this? HWP is not a solution for this model as graphics are not properly accelerated/power managed. on a side note I'm kinda confused why lots of people say to try different SMBIOS definitions to generate an SSDT when only 1 (MacBookPro13,3) matches my CPU and will properly implement CPU power management. Seems to me that SMBIOS is not arbitrary and that the really important thing is getting the correct frequency vectors to work. update: just saw this on Piker's blog "Update: HWP is set to 1 (enabled) in the FrequencyVectors data in the plists." if HWP is enabled in the frequencyvectors data of Mac-A5C67F76ED83108C.plist (MacBookPro13,3 plist) then how would I disable it? Having HWP + generated SSDT will cause KP so maybe this is the problem? Here's the hex data:

just wanted to say I got MacBookPro13,1 working with generated SSDT in 10.12.3. I added that system definition PlatformSupport.plist in /System/Library/CoreServices and it works. Battery life isn't great at around 4 hours, but CPU/GPU seem to be scaling properly.

Are you on Sierra or El Cap? Im on Sierra now and sticking to it. I don't need FakePCIID_Intel_HD_Graphics for internal display to work, maybe thats the issue. Will install that + FakePCIID_Intel_HDMI_Audio and see if I have any luck. Are you patching AppleIntelSKLGraphicsFramebuffer? Are you using a generated SSDT with MBP13,2? I'm still getting KP with MBP 13,3 + generated SSDT. I tried changing Freq Vectors with Piker's script to MBP13,3 but no luck. Rehabman says HWP doesn't load X86platformplugin which means GPU power management doesn't fully work with HWP so I think using generated SSDT is still the way to go despite all the XPS guides recommending HWP. And apparently Apple isn't using it all yet so its a risk scaled resolutions don't look good, I used HiDPI resolutions enabled by RDM and it looks ok with 1280x720 HiDPI resolution. I might try setting a custom HiDPI resolution with SwitchResX though

No just the 530

The only way I could get HDMI to work was to change corresponding board ID config to none in AppleIntelGraphics kext then reboot with hdmi monitor connected. Internal screen stays dark but external display works. No hotplugging and if you want to get internal display back you have to reboot. Maybe that helps you until you get HDMI fully working. I'll be attempting that once I get a new SSD (old one was defective and causing CPU DPC latency issues). We need HDMI/VGA + MacBook Pro 13,3 SSDT to have a fully working e5470 hack (apparently HWP does not enable proper GPU power management)

I've had some kexts not work in /L/E/ that work in /S/L/E. Also IntelMausiEthernet.kext has been spotty for me, often requiring a restart to show 'connected' in system prefs -> network. I'd also try the latest version 2.2.0d

that worked, thnx

yes I was able to decompile, patch, and recompile all SSDTs just fine.

so I went back to 10.11, got a bunch of data corruption with HWPEnabler and figured if I can't use that I don't really need Sierra. I thought I was home free until I tried to patch DSDT- I got some syntax errors that are usually cleared up with ADBG fix but no luck this time. Rehabman updated his maciasl and iasl builds yesterday which is what I'm currently using so maybe that has something to do with it. see attached for file, thanks DSDT.dsl.zip

I was referring to patching AppleIntelFrameBufferAzul.kext to get HDMI video output working. It looks like that only works for desktop Intel HD530 graphics (platform ID 1912000) I'd like to stick with MacBook Pro 13,2 SMBIOS for HWP support so changing to Haswell MBP SMBIOS isn't a viable workaround for getting HDMI video output to work. I also tried the 'Fix HDMI output' kextstopatch from the XPS 15 guide at insanelymac without luck: http://www.insanelymac.com/forum/topic/319766-dell-xps-9550-detailled-1011-guide/

cool, audio working now. I'll have to patch frame buffer myself, I really want to stick with MacBook 13,2 SMBIOS. Is there a way to get DPI scaling options in system prefs -> displays? The text on my 1080p 14" screen is kinda small...

any idea how I can get audio going in Sierra on this laptop? I've installed AppleHDA_ALC293.kext and EAPDFix.kext from 7x70 bootpack and latest version of CodecCommander from Rehabman. I also have the HDAS -> HDEF DSDT patch active in config.plist and 4 AppleHDA kextstopatch entries from this post- https://osxlatitude.com/index.php?/topic/8289-trouble-installing-yosemite-on-dell-latitude-e5450/page-5&do=findComment&comment=52447 This was enough to get audio working in El Capitan but not in Sierra. And no HDMI video output working. Any help is greatly appreciated as always, thanks

Ideally I'd like to switch off between a high performance mode when producing music in ableton live (where battery life isn't a concern) and a low performance mode with good battery life when doing everyday browsing/web stuff. I did use the beta branch of SSDTprgen and still got a KP when booting generated SSDT with MacBook Pro 13,3. Looks like HWPEnable is the only current working way to fine tune performance with this CPU and correct SMBIOS in Sierra- https://github.com/goodwin/HWPEnable

Yeah I gave up on SSDTprgen and used HWPEnabler. Let's me use MacBook Pro 13,2 SMBIOS, Does what I want it to do and is flexible. Geek bench performance for single core was good at 3501 but kinda low on multi core at 12051. Based on intel power gadget speeds are between 3-3.2ghz when using the correct speed limits for 6820hq CPU. Might have to tinker with it some more and hopefully performance improves with sierra updates. Battery life isn't great on lowest CPU profile with CPU running at .9ghz, only about 3 hours for a full charge. I was getting 4.5hrs prior to loading patched DSDT/SSDT. I'm wondering if GPU PM is enabled, Renaming GFX0 to IGPU for all SSDT/DSDT is all that's required for GPU power management to work on an intel 530 right? AppleIntelInfo displays P states for the GPU but again geekbench scores were low for my model...

What I think I want is running at 2.7ghz constantly. I produce music with Ableton live and performance in large sessions with lots of vst plugins suffers due to the latency introduced with intel speedstep. I basically just want high performance mode all the time, I don't care about battery life, fan noise or heat (as long as I don't melt my CPU lol). I plan to switch between this mode and regular CPU power management when producing and doing basic stuff (surfing web etc).Would nullcpupowermanagement.kext accomplish this? Also I managed to install sierra with this laptop and have everything working except audio, external video and CPU power management. When I generate a SSDT with SSDTprgen I get a kernel panic when using MacBook Pro 13,2 smbios. Using a generated SSDT with iMac 17,1 works fine though. Any ideas what could cause this? See screenshot, thanks

E5470 with i7-6820HQ and HD530 graphics running El Capitan. If I wanted to use the latest Macbook Pro 13,3 SMBIOS (which has same processor as my E5470) would i have to upgrade to Sierra? I tried changing SMBIOS in clover configurator then rebooted but got a 'OS not supported' error. and I'd like to have the option to run the CPU at 100% (2.7ghz native speed) with no throttling or power management, is this possible? thanks

No I get a kernel panic when it tries to load AppleIntelInfo.kext . Same thing with safe mode too :/

Ok I'll try that out thanks I accidentally installed AppleIntelInfo.kext to S/L/E/ and now my system won't boot. I managed to delete it by booting into windows. How would I rebuild the kext cache from terminal off the USB installer?

first kextstopatch isn't working, I get a video out to my monitor via HDMI but internal laptop screen cuts out then external monitor gets garbled and cuts out after a few minutes. I read ports 0, 5, 7 correspond to internal, HDMI and VGA ports, do you know what strings those ports correspond to and how to patch accordingly? also audio doesn't work after resuming from sleep

cool, all done with that and working. is there a kextstopatch to get HDMI/VGA ports working?

Yes IntelBacklight.kext is installed and Brightness Fix is patched to DSDT. I have slider in system prefs but no brightness icon when pressing f11/f12. Will try Karabiner setup. Should I patch DSDT with GFX0 -> IGPU for GPU power management?

I went for SSDT, I've got P and C states and better battery life so pretty sure power management is working. Is HWP stable? I read some sketchy things about resuming from sleep. Also how do I get GPU power management working? And is there a patch for FN keys controlling backlight? I have coarse backlight control via F11 + F12 and the slider in system prefs using 'Brightness Fix' DSDT patch but there's no brightness meter icon when using F11+F12. Occassionally the system will freeze for a couple seconds when adjusting brightness via F11 + F12. thanks

Ok audio is working. Now I just need to setup CPU power management. Should I use SSDTprgen or enable HWP in clover? I also need to do GPU power management right? And set correct ports for GPU.
