Lenovo ThinkPad T420 with UEFI Only

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

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.

      Ciao ragazzi! Grazie a questo forum con gente fantastica, sono riuscito a installare OS X e in seguito Win 10 su Clover SULLO STESSO HARD DISK
      Ho un problema, di solito utilizzo Kali Linux, la famosa versione di linux in usb in live
      Ora avrei la necessita di dedicargli 15gb di partizione del mio Hard Disk PER INSTALLARLA, e l'ho fatto effettivamente creando una partizione VUOTA tramite utility disco di Sierra.
      Il problema sorge quando io vado a riavviare il pc e quindi ritrovandomi nella schermata di clover, e vedo sempre il solito OSX e il recovery Osx e al posto di Windows 10, mi trovo la partizione di 15gb che avevo creato per windows(con l'icona di windows)
      Siccome ho paura di perdere i dati importanti che avevo su windows, non ho continuato installando Kali, ma mi sono fermato e ho eliminato la partizione sempre da utility di Sierra e come per magia, riavvio e Win10 è di nuovo lì dove dovrebbe stare
      Appena creo la partizione vuota, clover me la sostituisce
      Che devo fare raga?
      Io voglio OSX,Win10 (Che già ho) e Kali(Solo 15gb) sullo stesso hard disk
      Senza perdere dati di Win o Mac
      Gengik ho visto in precedenti discussioni tue, di andare in GUI da clover config . e togliere Windows da quelli nascosti e l'ho fatto, ma il risultato non cambia.
      Grazie per la lettura

      Hi All
       
      I'm trying to start a Hackintosh High Sierra 10.13.5 installation:
      - MSI B350 PC Mate
      - Ryzen 5 - 2600
      - Radeon Pro 580 GPU
      - 4 x 8GB DDR4
      (Have a working clover bootloader for HS 10.13.3 - but for some reason, I can't use that setup with the 10.13.5) 
       
      Have tried different bootloader setup, with different outcomes...
      ATM. I get this error/hang - "Unknown CPU: family = 0x17, model = 0x8, Stepping = 0x2"
      Have search google, and can see that the threads ppl. are getting this, is when they look at "About this mac", I haven't yet installed the OSX.
       
      So can someone help...

      I'm running the newest Kexts: AppleALC, FakeSMC, Lilu, RealtekRTL8111, USBInjectAll and WhateverGreen.
      In Bootloader setup, i'm running: -v, -s, -f, -no_compat_check, busratio=34, PCIRootUID=1, npci=0x2000, dart=0 and nv_disable=1
      In SMBIOS i'm using the iMac18,2 and in RT i'm using BooterConfig: 0x28 and CsrActiveConfig: 0x67
      In installed drivers i'm using: AptioMemoryFix, EmuVariableUefi-64, OsxAptioFixDrv-64 (Have tried Fix2 as well)
       
      But i'm, keep getting the Unknown CPU hang/error, can someone help...
      Or do someone have a setup with the same CPU and GPU, that can show me his/her setup for Bootloader/Kexts...
