Lenovo ThinkPad T420 with UEFI Only

4,550 posts in this topic

Recommended Posts

I used the updated t420 package and was able to boot from the USB.

On the T420, I installed over my old installation, and still have the issue of no display. If there was something in my old System folder causing this, wouldn't the installer have wiped out my old System folder? 

I guess the next step would be to wipe the drive clean and do a completely fresh install. Is there any way to access Finder from the booted installation USB, so that I can save any files I have on the system drive that I might want to keep? I am aware I can copy files around via the command line, but I'd rather not. My HD is an mSATA SSD, and I have no adapters for it, so I can't just pull it out and put it in an external. If not, would a live Linux distro be able to read the macOS drive?

i would try not injecting graphics with Clover first? did you try to increase brightness with SrcLck/Pause? i have been fooled by that.

I did a fresh install tonight, and all is well. I did find the newer zip you posted and used that for the last 2 attempts (the non-fresh and fresh.)

Before the fresh install while I was having the no-display issue, I did try the brightness keys. They would indeed adjust the brightness of the back light, but the screen was still displaying black. This was using the Fn+Home/End. I saw the Pause key mentioned somewhere and pressed that as well. Is Pause/SrLck a different brightness control? I also had tried the external DP displays on both the laptop and dock, but one thing I did not try was the VGA outputs.

But it's all good; I realized after poking around in Terminal for a bit that I had already backed stuff up to the secondary HDD in the laptop back when I first upgraded to High Sierra and thus didn't really have anything on the main drive to back up. I just wiped it clean and it was no big deal, just have to reinstall a few things. It would have been nice to figure out what the issue was in case it happens again, and future OS upgrades are still going to be scary on this thing, but I'll deal with them when the time comes.

I was also previously experiencing the occasional lock ups on both the T420 and T520, so it's good to hear that this has went away? Other than that, the only issues I have with them is with the occasional lines and artifacts in app windows, which I understand can be caused by low quality RAM? I'll have to swap a few sticks around and see what happens.

Thanks for the help and advice, not to mention the great guide for these machines!

@tluck Thanks for fixing it. It works for me now. I was able to install High Sierra on T420. What external wifi usb do you recommend? Will any work?

@copperspeed

there are several mac supported USB Wifi adapters. For example: I have one from ASUS N-10. and there are some other by RealTek (RTL), or TP-Link etc

So far so good. The blank screen thing did come back on one boot, but on the next reboot it was fine.

I've also had lockups yesterday and today. Both involved Safari, when clicking either the URL box or the tabs. There were times in the past where lockups were always while using Safari. Does anyone else have issues like this- lockups only when using Safari?

It kind of sucks- while I'm normally a big fan of the newer Firefox, Safari is zippy as hell when it comes to web apps I use for work. I'm going back to Firefox and see if I can make it through a work day without a lockup.

@tluck what's the deal with Clover these days ? It's been nearly 2 months since the last Clover update on Sourceforge, and only thanks to your Clover build I was able to install 10.13.4 on my spare laptop

@vusun123 - no idea why there isn't a recent build on SF? I just build my own package of course! how's things with you!? 

@copperspeed -  is your headphone stuck? i would perhaps put a headphone in and out a few times? I don't have low volume problem with my T420. what is your system - please create a profile in your signature.

Hi guys, using this guide and files for a while now in Sierra, all good , thank you very much!

However, I need to upgrade to High Sierra now (iPhone updated to 10.3 -> latest xcode version in Sierra can't work with that etc -> Need High Sierra and a newer xcode version).

I used AppStore to download High Siera. It did start the process of updating, but when I get to the part to select the HDD where to install it doesn't want to accept the HDD macOS I am using (Saying the it's missing the firmware partition).

I tried to follow the 2.3 steps from the guide to no avail. 

Also I don't understand the meaning of

"

  1. Manually mount and install of the ESP bits to disk0 by following the same procedure as for the USB.

"

Other that I tried everything I could think of. 

Thanks in advance!

Hi, I need your help.

yesterday I had to reinstall High Sierra on my T420. All is working fine with the latest Clover.zip package. But after wake from sleep my power led and sleep led on the cover keeps flashing.

Everything else works fine after sleep. I need to reboot, of course, for both leds to stop flashing.

 

Do you have ideal what can cause that? I have disabled hibernation and removed sleep image (hibernate mode set to 0).

OK I think I found the problem. For many years I had installed external disk in CD Bay instead of CD Drive. When I put CD Drive back, or just remove the external drive from CD Bay, led behaves as it should. So something is not right with the external drive sitting in the cd bay, then.

Hmm, I also have a HDD in my CD bay, maybe that is my problem. Oh and it's a m2 SSD in an adapter  that is in the CD bay and my macOS boots from it. I guess I should try switching the drive to the main bay.

Another strange thing is that I got a downloaded version of the installer (macOS 10.13.1) to try. And it does see the hard drive and starts the installation process, but when it restarts I choose the macOS install from the menu (Clover?) and after the Apple logo with the loading bar finishes loading, I get a the Prohibitory Symbol....

Hopefully this information will give more insights for the person who is willing to help.
Thanks!

Does anyone else get the occasional line flickering on the display? Also, has anyone else got a problem with the laptop not going into sleep when the lid is closed? I suspect that Mail is misbehaving, as it also prevents shutdown until forced to quit.

I get the line flickering and random lines and artifacts through windows that are open sometimes. I've read that it can be from poor quality RAM. I'm not sure what constitutes good vs. poor quality; I've tried switching RAM around between a few different brands, making sure to use the same kind of stick in both slots, but it didn't help. The same RAM works fine in Windows.

I find that it's predominantly in videos, including those on Facebook. Often consisting of one band but occasionally two running across the video. It does however also manifest in some other applications. I'm not sure if it's a RAM issue, appears to be more of a driver issue to me.

      What works and what does not
       
      - Processor: Intel Core i5-4300M ->  Work. All SpeedStep stages.
      - Video Card: Intel HD4600 ->  Work. QE/CI and Metal.
      - Chipset: Intel QM87 ->  Work.
      - Mini DisplayPort ->  Work. But no audio, yet.
      - VGA ->  Not work. Normal.
      - Audio: ALC292 ->  Work.
      - WiFi/Bluetooth: Intel AC 7260 ->  Not work. Replaced with DW1560 (need whitelist removal).
      - Ethernet: Intel I217-LM ->  Work.
      - Card Reader: Realtek RTS5227 ->  Not work.
      - Keyboard and Touchpad ->  Work.
      - Webcam ->  Work.
      - Fingerprint Reader ->  Not work. Normal.
      - USB3.0 ->  Work.
      - Sleep ->  Work.
      - Airdrop, Handoff, Instant Hotspot and Continuity ->  Work after replaced wireless.
       
       
      Extras
       
      - FullHD 1920x1080 display upgrade: 
      Replaced with AU Optronics B140HAN01.1 30pin eDP (B140HAN01.2 and B140HAN01.3 also compatible).
      Apparently same screen as Dell Latitude E6440, E7440, Lenovo Ideapad U430 and E129.
       
      - CPU upgrade:
      Replaced the stock Intel Core i5 4300M 2.6Ghz (3.3Ghz turbo) 6M cache with Intel Core i7 4700MQ 2.4Ghz (3.4Ghz turbo) 6MB.
      I initially had problems with overheating. The processor ran at full load above 90 degrees.
      After using a quality thermal paste I can work between 70 and 80 degrees.
      Acceptable taking into consideration that the new processor has 47TDP versus 37TDP which is recommended.
      I also had no problem consuming the battery while charging. The original 65W source seems to have figured out.
       
      - Touchpad upgrade:
      Replaced the stock with T460 touchpad.
      This is serious: you have to do it! It should be stock. Touchpad with precision and absurd quality!
      Just do it!
       
      - RAM upgrade:
      No mistery here. Just upgade.
       
       
      Todo
       
      - Make DP audio work.
      - Make Card Reader work.
      - Upgrade CPU to i7-4712MQ (Ordered. It's on the way) Done, but received i7-4700MQ (47w TDP, with good paste I have no overheating)
      - Replace touchpad with T460 model (Ordered. It's on the way) Done. Sensitivity and perception of quality much better. I recommend 100%!
      - Sierra Gobi5000 4G LTE modem EM7355 (Ordered. It's on the way. I hope works. ) Done, but not work. Recognize but not connect. I already gave up...
      - Upgrade to 16GB RAM Done

      - macOS Mojave install app
      - Clover EFI
      - Clover Configurator
      - Some KEXTs and SSDT patches


      How create create the install flash drive

      Format the flash drive with GUID partition mapping and name it "Install".

      - Open Disk Utility.
      - Click in View, then "Show All Devices".
      - Select the destination flash drive, then Erase.
      - Name: Install, Format: Mac OS Extended (Journaled) and Scheme: GUID Partition Map
       
      Create install flash drive

      Open terminal and run this command:

      Install bootloader

      Download the RehabMan's CloverEFI fork (used 4701) and install with this options on "Install macOS Mojave":
       
      - Install for UEFI booting only
      - Install Clover in the ESP
      - UEFI Drivers - ApfsDriverLoader-64
      - UEFI Drivers - AptioMemoryFix64


       
       
      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.
      - Download the Lilu.kext from here. I used the version 1.3.1.
      - Download the AppleALC.kext from here. I used the version 1.3.4.
      - Download the VoodooHDA from here. I used the version 2.9.1.
      - Download the WhateverGreen.kext from here. I used the version 1.2.6.
      - Download the AppleBacklightFixup.kext from here. I used the version 2018-1013.
      - Download the USBInjectAll.kext from here. I used the version 2018-1108.
      - Download the ACPIBatteryManager.kext from here. I used the version 2018-1005.
       
       
      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

      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.
