I was googling around and found https://github.com/Piker-Alpha/AppleIntelInfo

I loaded AppleIntelInfo.kext and then ran  sudo cat /tmp/AppleIntelInfo.dat command

 

The output only shows me P-States and no C-States. Is that ok?

when runnin the SSDt generation script in this guide I get the following output:

@OscarS - great story. glad everything is working out for you.

 

@Somez- do you have the modded bios where you can change the thermal settings? are they the same settings?

do have the same HD in each machine. a SDD runs a lot cooler. idle while writing this the CPU temps range from 41-44C (106-108F).  the FAN is running around to 1958rpm. 

my son has same computer but his runs a lot hotter for some reason.

@tluck my bios has that option (prolly because it was the latest bios found -date of upload-)

Looks to be version 1.46. I have that version with whitelist disabled, but without these advanced options. I guess I can't flash this one without Windows :)

I was able to make an Ubuntu live USB and checked temperatures under Ubuntu. It was the same what I get in macOS so I'm starting to think the issue is with the hardware.

I got my DW1510 wifi card, flashed the bios, got wifi under windows, but nothing under OS X (I am using el capitan).

Under System Preferences / network I don't have the wifi card listed (only ethernet, pci serial adapter and firewire).

Any suggestions/tips?

Guys!

 

May I ask those who can reach cpu temperature around 41 C and fan speed around 2000 RPM to check what's the part number of their heatsink? It's located under the keyboard and starts as "FRU".

 

Thanks.

@Somez

In my experience it depends also on the specific heatsink/fan piece itself, not only if its single thick/double thin pipe heatsink, and different fan.

I had the 04W0627 which cooled very well the 2520m, but the 04W0407 worked better for me with the quad processor (idle now at 36 C/1962RPM, but its winter ;) ). Altough for some people it was the other way around, check out this thread if u understand german (https://thinkpad-forum.de/threads/170582-Erfahrungsberichte-Quadcore-im-T420-Mod-Bios-inside).

My gf's t420 has the 04W0627 with 2540m cpu, and its not cooling as well as the one i had (don't know if it just needs repasting, or else...), I can hear her fan spinning up a lot, just with browsing..

@davidian

 

- did you add the extra kexts for Broadcom support?

 

see this post http://www.insanelymac.com/forum/topic/285678-lenovo-thinkpad-t420-with-uefi-only/?view=findpost&p=2297730

@tluck

thanks for the link

I tried, but I must've missed sthing, or not did it properly, cause it still doesnt show up (do I also need to do some dsdt patching?)..

Should I install all the 4 kexts with kext wizard? I installed only the Brcmxxx.kext ones, the FakePCIxxx are in EFI/Clover/kexts/Other.. maybe this is wrong?

I might order a 04W0627 and try out how that works.

@somez - i will check my 2 T420 systems for the Fan FRU. if you install the modded bios with adv menu that provides more control of fan vs temperature.

 

@davidian - install all 4 kexts in /Library/Extensions - one way is to use the zip script from the Guide -  if you add these kext to the T420/EFI/CLOVER/kexts/Other folder then run the _kext-install.command scripts.

the EFI kext folder is skipped when there are kexts on the HD. The EFI kext folder is just for OS installer and Recovery HD.

Thanks tluck. Can you point me to a place where I can download that BIOS?

I guess I have no choice but update the BIOS under windows, right? Because then I have to install Windows on my optibay HDD and then swap it with my SSD which has macOS on it.

I don't want to risk messing up my macOS installation with bootloader changes or anything like that.

@Somez - OscarS just posted a download of that BIOS - there are probably others if you search this thread.

 

Note: you can install and run Windows on the OptiBay without changing or swapping. i keep a windows partition on my optiBay disk (HD). To simplify windows installation, it may be best to pull your main drive though.

Argh, you're absolutely right, I've just downloaded his BIOS. Thanks for telling.

I'll pull my macOS drive just in case.

I did that, and no change (previously I did it in S/L/E).

The kexts are now in /L/E. I tried to see what kexts are loaded from these 4, but only FakePCIID is.

I tried to flash this modified BIOS using winflash but it told me I have the same or older version of BIOS which is correct. Is there a way to force it?

Thanks.

@davidian - what about the broadcom kexts? the FakePCIID_Broadcom kext just injects properties - there is no binary. the broadcom kexts load the firmware onto the card.

 

@somez - i recall installing that same bios on my 1.46? yes there is a way to reinstall etc. pflash or winflash.exe /sa xxx.bin

Thanks, I just did it with the following command: winflash.exe /sv /sd "83ET76WW\$01C8000.FL1"

With the new BIOS I get full resolution even at Clover menu during boot :)

Fan speed remains the same but I'll play with the advanced settings tomorrow. I don't have high expectations though.

I found out that

Vendor : Device Id is 14e4 : 4353 (Is this a problem? It was advertised as DW1510, BCM94322HM8L, but according to wiki it's DW1520 BCM943224HMS)

 

Now that I know I have a different model than the one ordered, I did some google-ing, and found out that it's probably apple whitelisted.

Anyone knows how to proceed from here?

@Somez: How did you fare so far with the extended settings?

Presuming you are using this 1.46 flavor there are lots of settings available.

$01C8000.FL1.zip

 

The RAM speed setting is the only obvious one to me, any thoughts what else might better a Hackintosh?

Well, I haven't changed any advanced settings so far. I'll try to play with the values for the low fan speed, e.g. to trigger low fan speed on higher temp. This will not cool my CPU down though...

After some googling and hex editing, I found a solution for my DW1520 (BCM943224HMS).

Add this to config.plist:

 

<dict>
<key>Comment</key>
<string>DW1520 Whitelist Patch (MBP8,1)</string>
<key>Disabled</key>
<false/>
<key>Find</key>

<key>Replace</key>
<data>
TWFjLTk0MjQ1QjM2NDBDOTFDODE=

It works without having installed the FakePCIID and Brcm kexts

Hey guys. I am just wondering if anyone has made the update to 10.12.2 ? And if it breaks anything?

I don't have my back up drive going yet so I am holding off.

 

10.12.2 is a magic update! It removes the battery time remaining for new macbooks!  SMH.

      Budget Workstation MacOS 10.14.1 build: z370 AORUS Gaming 5 - i5-8600K - RX 580 - UHD 630
      flawless iGPU/dGPU integration, fast FCPX editing/rendering, great overall performance for ~$1200 / ~£1000
       
      Update: updated WhateverGreen and Lilu, then updated OS to 10.14.3 and everything is fine! Even iMessage, which previously I hadn't been able to make work, is now working - possibly the update flushed the NVRAM?
       
      I'm gonna come straight out and admit it - I used newb tools which are considered taboo on InsanelyMac, and so this isn't so much an installation guide as it is a green flag to anyone considering the same hardware. My first and previous Hackintosh project was just over ten years ago and this site was massively helpful, so this is my (very small) way of giving back.

      HARDWARE
      CPU: Intel i5-8600K 3.6GHz hexacore (contains UHD 630 iGPU)
      CPU Cooler: be quiet! Pure Rock Slim (no paste needed, and fan facing front)
      Mobo: GIGABYTE z370 AORUS Gaming 5 (WIFI)
      RAM: 1x 8GB CORSAIR Vengeance LPX C16 2666MHz (in first slot)
      GFX Card: Sapphire RX 580 NITRO+ SE
      SATA: used ports 0, 1, 3, 5 (HDD problems when connected to port 4)
      HDD: generic
      DVD Drive: generic
      PSU: EVGA 500W Semi Modular (but you should get 650W!)
      Case: CoolerMaster CM590 III
      Fans: 2x stock case fans (one sucky on front, one blowy on back), 3x be quiet! BL046 120mm fans (two blowy on top, one sucky on front). Airflow near-perfectly balanced.
       
      ADVICE
      With the Clover configuration, you want to pay close attention to all things relating to graphics. There are some specific settings for ACPI, Boot, Devices and Graphics which should be copied exactly in order to get the iGPU and dGPU to work in perfect harmony. For instance, make sure you use ig-platform-id 59120003 rather than 59120000 if you want FCPX to be usable. With the right settings, FCPX will not only run, but run flawlessly.
       
      I was not able to figure out how to make NVRAM/PRAM behave itself, and I got errors when I tried to issue relevant commands. As a result, I could not at first get iMessage to work properly. It worked once on my first installation attempt but not from subsequent attempts. This Clover configuration therefore has no consideration whatsoever toward iMessage reliability - however, iMessage ended up working somehow, anyway - I noticed it after I'd updated to 10.14.3 but this may just have been coincidence.
       
      Onboard WiFi does not work. There is no driver for it. I'm using wired ethernet to a bridge router as it was cheaper than getting a compatible PCI card.
       
      Audio is working well after I installed the z370 audio patch, then the ALC1220 codecs, then AppleALC.
       
      With kexts for generic 3rd party SATA and generic 3rd party eSATA, my HDDs and DVD drive work perfectly well.
       
      Sleep/Wake functions run perfectly. iCloud functions run perfectly. Shutdown leaves the mobo LEDs on, annoyingly.
       
      My USB 3 ports seem to suffer from low power output, and I don't know why.
       
      Overall, this system appears to run about as well under MacOS 10.14 Mojave as it does under Windows 7. I would solidly recommend this build to anyone looking to build a computer for workstation purposes, on a budget.

      Good morning, everyone, I'm sorry if I was wrong in choosing the topic but I need help.
      I have found it extremely difficult to mount a Hackintosh in my acer.
      Setup;
      I5 2430m 2.4 6GB RAM
      Mobo P5we0 - Intel intel Graphics 3000
      At the moment I have not found out what my audio codecs are.
      but I'll leave the link on the motherboard.
      however, my real problem is several.
      I have already used the itakos image, I have already used several images that could be installed normally and that after installing the image I do not have internet via cable or wireless.
      And another, I already looked in other forums and I know that I will be called a donkey in the logical question but I have not been able to install the [url=&quot;http://www.insanelymac.com/forum/topic/279450-why-insanelymac-does-not-support-tonymacx86/&quot;]#####[/url] or clover to start from the Hard Disk, so I do not know what to do.At the moment I still do not know if there has already been someone who has already installed the High Sierra or just the Sierra in this notebook model and obtained permanent success.
      If anyone can help me, I'll be grateful.
      Installations without success, but with the system already installed in ACER;
      SIERRA
      HIGH SIERRA
      MOJAVE
      All with the same symptom. Starting only by the bootable USB stick and without internet connection via cable and wireless.

      Since rev 4844 Vector Themes are supported and there are ready-to-use Clovy by Clovy, cesium by Slice and BGM_SVG by Blackosx.
      You may see it's structure to create own theme
      -------------------------------------------------------------------------------------------------------------------------------------------------------
       
       
      Now I want to add vector graphics support in Clover. See rev 4560 and later.
      It is not working yet but designers may begin to create Vector Themes.
      It supposed to consist of SVG elements and has design size. It will be rendered to any screen size scaled from design size.
       
      What application in macOS can create SVG graphics?
      Inkscape is not working in macOS 10.11+. Pity.
      LibreOffice Draw works with SVG but buggy.
      Boxy SVG cost 10$ but looks good enough. It creates the best in simplicity files and have more then enough features.
      Illustrator is good but expensive.
       
      How to improve SVG file?
      Clover has restricted support for SVG. It is your job to make compatible file and as small as possible to speedup rendering.
      Some helps:
      Help:Inkscape – From invalid to valid SVG Inkscape files
      From invalid to valid SVG Adobe Illustrator files
      From invalid to valid SVG files of other editors: BKchem, ChemDraw and CorelDRAW
      Help:Illustrator – Assistance with creating and saving SVG images in Adobe Illustrator that will pass W3C validation
      User:Quibik/Cleaning up SVG files manually
      Later I will write own instructions specific to Clover abilities.
       
      How to create SVG fonts?
      You can google to find ready-to-use SVG fonts.  I found some problems with too beaty fonts: slow rendering and overflow crash. Be careful.
      You can get ttf or otf fonts and convert them into svg by using online WEB services. Not a problem to google.
      But then I want to find a way to simplify the font to reduce a size and speedup rendering.
      You can create own font by FontForge It is opensource and available for Windows, Mac and GNU+Linux. It creates otf font which you can convert to svg font.

      Make things works

      Will be created a partition named EFI and mounted in Desktop.
      - Replace the /Volumes/EFI/CLOVER/config.plist with mine attached below
                    If you have modded BIOS with Advanced Menu and enabled 128MB DRAM-prealloc use 128MB_DRAM-prealloc_config.plist.zip
                    If no, then use 32MB_DRAM-prealloc_config.plist.zip
      - Put SSDT-L440.aml attached below in /Volumes/EFI/CLOVER/ACPI/patched/
       
      Generate your Serial, MLB and SmUUID
       
      - Open the replaced config.plist with Clover Configurator (used 5.3.2.0)
      - Go to SMBIOS, click few times in "Generate New" in Serial Number and SmUUID.
       
      Download those Kexts and put in /EFI/CLOVER/kexts/Other/
       
      - Download the FakeSMC.kext from here. I used the version 2018-0915.
      - Download the VoodooPS2Controller.kext from here. I used version 2018-1008.
      - Download the IntelMausiEthernet.kext from here. I used the version 2018-1031.

      Wifi and Bluetooth (DW1560 / BCM94352Z)
       
      Unfortunately, some notebook manufacturers are currently blocking the replacement of wireless cards. They want you to only use the models sold by them. And of course, none of them from Lenovo for this notebook model is compatible with MacOS.
       
      If you try to start with an unauthorized wifi card for them, you will receive a screen error:
      1802: Unauthorized network card is plugged in - Power off and remove the network card. Since this check is done directly in the BIOS, the only solution is to modify it.
      But since nothing is easy in this life, there is one small big problem:
      - The BIOS update procedure does not allow you to use modded files as it used to be.
      - You will need to physically reach your BIOS on the motherboard and make use of a USB BIOS reader/writer.
       
      So what you need to do:
      1. Disassembly your laptop;
      2. Dump your BIOS with an USB BIOS reader with SOIC8 clip (to not desolder from the motherboard);
      3. Patch it (In addition to removing the whitelist, add the advanced menu);
      4. Fix RSA signature;
      5. Reflash BIOS;
      6. Replace wireless card;
      7. Remount your laptop;
      8. Done.
       
      Soon, I'll provide step by step in this process. Probably until end of this week.
      In the meantime, if you need to, send me your dump that I do steps 3 and 4 for you.
      I also add the Advanced Menu so you can increase to 128MB the DRAM-prealloc.
       
      To fix a Modded BIOS to remove the 5 beeps on boot, you need this guide: https://www.insanelymac.com/forum/topic/337333-guide-fix-insyde-h2o-bios-signature-5-beeps-on-lenovo (traduzido: pt-BR)
       
       
      After replaced the wireless card. Download those Kexts and put in /EFI/CLOVER/kexts/Other/
       
      - Download the AirportBrcmFixup.kext from here. I used the version 1.1.9.
      - Download the BrcmFirmwareRepo.kext and BrcmPatchRAM2.kext from here. I used the version 2018-0505.
      - Download the BT4LEContinuityFixup.kext from here. I used the version 1.1.2.
       
       
      Now you can start the instalation without problem (I guess).
       
       
      How install
       
      UEFI Setup Configuration and Installation

      UEFI configuration
       
      My BIOS is the latest: 1.93 (J4ET93WW) 

      - Shutdown and insert the flash drive.
      - Power on with F1 pressed to enter BIOS setup.
      - Change value: Config - Intel(R) AMT - Intel(R) AMT Control to DISABLED
      - Change value: Security - Security Chip to DISABLED
      - Change value: Security - Anti-Theft - Intel(R) AT Module Activation to DISABLED
      - Change value: Security - Anti-Theft - Computrace to DISABLED
      - Change value: Security - Secure Boot to DISABLED
      - Change value: Startup - UEFI/Legacy Boot to BOTH, Legacy First and CSM Support = Yes
      - Save & Exit Setup (F10)
       
      - Now, hold the F12
      - In the list, select your flash drive.
       
      The installer will start. 
      
      Format destination disk

      Format the disk with GUID partition mapping and name it "Macintosh".

      - Select Disk Utility in the list, then press Continue.
      - Click in View, then "Show All Devices".
      - Select the destination Disk, then Erase.
      - Name: HD, Format: APFS and Scheme: GUID Partition Map

      Close Disk Utility.
      
      Select "Install macOS", then Continue.
      Follow instructions in screen.

      After install

      After first part install the system will reboot. Maybe you have to press F12 again and select the flash drive.
      
      The second part of the installation will begin. This will take 16 minutes.
       

      Post installation

      Install bootloader
       
      When the second part of install finish, the system will reboot again.

      After performing the user initial setup and go to the desktop, you need to install Clover on internal disk.

      Open the Clover installer inside flash drive that you copied before.

      Use same options above but choose the system partition this time.

      Now you need to replace the config.plist inside your destination disk EFI parittion with config.plist inside flash card EFI partition.

      The flash drive EFI partition is unmounted. Mount with terminal "sudo diskutil mount /dev/rdiskXs1". To know what X is, use "diskutil list", most likely is 1.
       
      Last step
       
      Copy all Kexts from flash drive to /Library/Extensions, with those commands in Terminal:
      sudo cp -R /Volumes/EFI/EFI/CLOVER/kexts/Other/* /Library/Extensions/ sudo chmod -R 755 /Library/Extensions sudo chown -R root:wheel /Library/Extensions sudo kextcache -i / Restart the system.
       
       
      It's done!
       
       
      Updates
       
      System update 10.14.3
       
      - Updated with success;
      - Everything works perfectly after reboot;
       

       
       

       
      And last but not least
