You might need the Wi-Fi driver too, depending on your card and whether you use it. Personally, I would move to High Sierra rather than Mojave

 

If I recall correctly its a DW1520.

The only reason I'm considering trying out Mojave is because of Dark Mode.

@davidian - I successfully tested the HD3000 kexts from Sierra and High Sierra with Mojave, but i recall a failure with the el cap gfx kexts. 

High Sierra is the last properly supported version for aHD 3000 system like the T420

 

As bedfellow suggested, move to that (first) to get the kexts you will need to move forward.

 

if you have enough free space, perhaps create a 20 or 30 GB partition to test out mojave. For example, I dual boot using the same ESP/Clover config for High Sierra and Mojave.

Note: be prepared for APFS - all my disks are formatted with APFS now -  whether SSD or regular SATA now. 

 

and i use jackluke's script to switch from light to dark mode at night!

You'll need to copy the High Sierra Wi-Fi driver for that. Details are in tluck's install post.

@tluck, @bedfellow, thanks for the info.

@tluck, I read about the new apfs, is there any downside to it or it's just another file system? I'm asking because you mentioned it, and I don't know if it was  because I should watch out for something, or it was just a casual info..

 

I will move first to High Sierra, and then see from there.

I remember talk about the glitches since tluck was trying out the Sierra Beta, so I never felt motivated to move from El Cap.

If I manage to install HS / Mojave, maybe I won't have a problem with glitches or other gfx issues, because I use eGPU while docked.

For me, some of the more recent plist have helped with the graphics glitches, but they never truly went away until I upgraded the RAM to 16gb.

 

The light theme is Mojave does not work properly on the T420, I suspect due to the now unsupported graphics chip. I also found Mojave to be more prone to lockups than High Sierra.

So I created the usb installer, made an empty 50Gb macOS partition, but after booting from the usb stick, I cannot select that partition (or any). I'm getting "You may not install on this volume because the computer is missing a firmware partition".

Did I miss something, anyone got this before me?

I downloaded the full installer app (~5Gb) with macOS High Sierra patcher, since from the app store I was getting the 28Mb installer.

Sounds to me that you have not created a GUID (GPT) partition.

On the HDD? It's the same HDD where I have El Capitan installed, just created a separate partition and formatted it to Mac Os Extended (Journaled), so that must be GPT.

Disk Util says so..

Would it make any sense to try with a complete blank HDD?

So to answer my own question:

the problem was that the partition wasn't APFS.

In the guide it says macOS Extended (Journaled) or APFS.

For High Sierra macOS Extended is not accepted, only APFS (at least in my case with my installer is not).

I will later check if it's the same with Mojave.

I don't know if this is trivial info or not, I'm just glad I found out what was the issue.

If anyone thinks it's worth it, then maybe mention it in the guide, altough searching for the text that I posted in the thread give me no hits, so maybe it's just me.

I'm glad you have resolve the issue. When I dual booted HS and Mojave I had them on separate drives so didn't have this issue. If the information is useful to others then it's certainly not trivial.

You are the greatest tluck, thanks a bunch for your latest EFI package!

I was able to install Mojave on a spare old USB2 drive, AFS formatted.

Needed some re-boots, but all an all a hassle free installation.

 

One thing puzzling me, from the About this Mac, I'm getting 5 MB VRAM, is that what it should be?

I seem to recall that some kext from Sierra would better things a bit.

If that's still an option, which one should be installed?

 

Sorry for not recalling all proceedings in this thread.

Again, awesome work. Thanks for keeping our oldies updated!

Mojave removed support of HD 3000 Graphics , you need to copy the hd3000 kexts to /S/L/E , and than rebuild caches

Thanks, thats right.

Found the needful things three pages before.

Still a working package hosted here won´t harm much. ;)

 

Another problem did arise unfortunately.

I lost PS2 Trackpad and keyboard after booting from power off.

USB mouse and keyboard do work of course, but thats not comfortable with a laptop.

Just realized that sound is gone too. :(

Any thoughts how to get back the functionality from just after installation?

Other than that, the OS looks quite snappy, even from my old USB2 Fujitsu 120 HDD.

T420 2420M 8Go 1600*900 bought :) must received it wednesday  

my previous was 2440M 4Go 1366*768

i'm back soon :-)

 

Got both cpu flavours 1600*900 (Intel only) and honestly do not see a difference, performance wise.

RAM will matter and possibly an i7, but I don´t think upgrading the cpu is worth the money, SSD and RAM are the ones and possibly a expansion bay for backup etc.

hmm seems like some of the kexts are not loaded? I will try to find time re-test a complete installation.

anyway seems like a good idea to include the HD 3000 GFX/Atheros kexts in the repo as there seems to be a lot Mojave interest.

Thanks tluck.

As I was uncertain how to get back the trackpad function, installed from scratch again on the USB2 volume.

Until right now trackpad, trackpoint and keyboard do work. Same for sound, volume keys and camera.

Why the kexts were no loaded last time remains the question.

I´ll try some more, than replacing HS with Mojave will be on schedule.

 

I´m getting system crashes in an early stage, three out of four times.

I´ll try with my other T420, as there may be a ACPI issue as seen before.

The crash report (first lines) is attached.

 

For the lost trackpad and sound, could HWSensors be the culprit?

The devices did work on my second trial until installation.

Afterwards Trackpad and sound are missing and HWSensors are not loaded either - strange.

I still have the BIOS/UEFI stuff on a 1GB thumb drive.

My BIOS was at 1.48 with my last T420, lets hope the downgrade still works via DOS with BIOS 1.5.2

The bootable thumb drive is 1 GB, I´ll copy the needed files to a folder.

You will need to make a bootable volume from them to get into DOS for downgrading BIOS.

 

Here are the files: https://www.magentacloud.de/lnk/fvStA9ob

Good luck!

      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.

      - 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
      - Make trackpad appear in System Preferences

      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 2.0.0.
      - 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

      - 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 EFI folder inside your destination disk EFI parittion, with EFI folder inside flash card EFI partition.

      If the flash drive EFI partition of your destination disk or flash drive is unmounted:
      Mount with terminal "sudo diskutil mount /dev/rdiskXs1". To know what X is, use "diskutil list", most likely is 0 for destination disk and 1 for flash drive.
       
      Then, eject the flash drive.
       
      Last step
       
      Move all Kexts from EFI partition to /Library/Extensions, with those commands in Terminal:
      sudo mv -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;
       

       
       
      System update 10.14.4
       
      - Updated Clover to 4910.
      - Updated Lilu.kext to 1.3.5 and WhateverGreen to 1.2.7.
      - After first reboot the update progress stoped with:
      GTrace synchronization point 4 Unsupported CPU Unsupported PCH hmm.. mismatch sizes: 3100 vs 20 It was still possible to start the previous installation, selecting "Macintosh" as opposed to "macOS Install" in Clover.
      So I created a flash drive with Clover 4910 and put only my config.xml, SSDT-L440.aml, the updated Lilu.kext and WhateverGreen.kext. And I decided to test VirtualSMC instead of FakeSMC.kext.
      With this I was able to install update 10.14.4. After installation I can boot normally, even with FakeSMC.kext that already in /Library/Extensions.
      I do not know what exactly happened, but now works everything like was previously.
       


       
       
      System update 10.14.5
       
      - Updated Clover to 4934.
      - Updated Lilu.kext to 1.3.6 and WhateverGreen to 1.2.9.
      - After first reboot the update progress stoped again (like 10.14.4 update) with:
      GTrace synchronization point 4 Unsupported CPU Unsupported PCH hmm.. mismatch sizes: 3100 vs 20 It was still possible to start the previous installation, selecting "Macintosh" as opposed to "macOS Install" in Clover.
      I decided to rollback to FakeSMC.kext but this time with the version of HWSensors 3. Link above.
      With this I was able to install update 10.14.5. After installation I can boot normally.

      App alternative:
      ESP Mounter Pro: per montare la partizione EFI
      Vi illustrerò tre metodi per creare la usb, ma sono ben distinti… quindi usatene soltanto uno
      Metodo 1: “Install Mac_OS_X.command” Metodo 2: “Create Install Media di Apple” Metodo 3:  Metodo Manuale Alla fine delle preparazione dell’installer, tutti i metodi necessitano l’installazione del Bootloader Clover sulla a vostra USB.
      “CONDIZIONI OBBLIGATORIE”
      PUNTO 1: che la vostra usb sia stata preventivamente nominata USB (caratteri maiuscoli) Tabella di partizione GUID e la formattazione in  Mac esteso Journaled.
      PUNTO 2: che l’installer di OSX si trovi in Applicazioni
      Utility Disco 
      Selezionate la pendrive, andate su “partizione”, selezionate “1 partizione”, impostate Mac OS esteso journaled e date il nome USB, poi in basso cliccate su opzioni e scegliete Tabella partizione (GUID), poi “applica”.
      Immagine 
      Riporto nuovamente l’operazione sopra citata adoperando dal nuovo Utility Disco introdotto su El Capitan.
      Rimane ovviamente invariato nome della usb in ==>> USB (maiuscolo), la formattazione in Mac esteso Journaled e sia la mappa partizione in GUID
      Da utility disco selezionate la usb, cliccate su inizializza.
      dal menù a tendina scegliete la relative impostazioni
      Immagine  
      Procedura effettua da High Sierra è la stessa della precedente, l'unica attenzione e operazione da aggiungere in primis  è cliccare nel menù a tendina in alto sulla sinistra di utility disco e selezionare "mostra tutti i dispositivi"
      Immagine 
       
      =====================
        METODO 1: "Install_Mac_OS_X.Command" Lo script che trovate allegato in fondo alla guida permette la creazione dell’installer in maniera automatica
      Include la possibilità di scelta di tre versioni di osx
      Yosemite El Capitan Sierra Il risultato finale è come quello del metodo "manuale" descritto nella guida, per cui l'installazione avverrà in un solo passaggio, non in due come con il metodo createinstallmedia. 
      Offre inoltre la possibilità di inserire un kernel patchato, utile, per esempio, per chi usa AMD.
      Rimane invariato il nome dato alla usb in USB, mappa partizione e tipo di formattazione
      Se la vostra usb non sarà rinominata nel modo corretto, verrete avvisati dal terminale, quindi non dovrete far altro che apportare la relativa modifica e rilanciare nuovamente lo script
      Esempio
      ===========================
      Metodo 2 
      L'intento è quello di usare la procedura fornitaci direttamente da Apple, "createinstallmedia", introdotta  con Mavericks. 
      Tale metodo prevede l’uso del terminale che via via se ne sta perdendo il “valore e l’uso”
      Inizialmente per i neofiti potrà sembrare problematico ma alla fine non è così.
      Durante il post installazione alcune operazioni ne richiedono l’ uso.
      Perciò mi sono chiesto perchè, qualora uno volesse, non far conoscere da subito un po’ questo “strumento”???
      Per favorirvi vi ho allegato i comandi già  “pronti”, i quali li potrete copiare ed incollare sul terminale.
      A questo punto aprite il terminale, copiate ed incollate il comando sottostante e premete invio, digitate la vostra password e premete nuovamente invio.
      Comando per creare USB con Yosemite:
      sudo /Applications/Install\ OS\ X\ Yosemite.app/Contents/Resources/createinstallmedia --volume /Volumes/USB --applicationpath /Applications/Install\ OS\ X\ Yosemite.app --nointeraction  
      Comando per creare USB con El Capitan
      sudo /Applications/Install\ OS\ X\ El\ Capitan.app/Contents/Resources/createinstallmedia --volume /Volumes/USB --applicationpath /Applications/Install\ OS\ X\ El\ Capitan.app --nointeraction Comando per creare USB con Sierra 
      sudo /Applications/Install\ macOS\ Sierra.app/Contents/Resources/createinstallmedia --volume /Volumes/USB --applicationpath /Applications/Install\ macOS\ Sierra.app/ --nointeraction Per creare USB con Hight Sierra o Mojave usate --> C_I_M (aggiornato per 10.14)
       
      Funziona con il drag & drop sul terminale, in questo caso non vi è necessità che la usb sia nominata in un determinato modo ed essendo basato su create install media ovviamente funziona da 10.9 a 10.14.... 
      BENE…IL PROCESSO DI CREAZIONE E’ INIZIATO…
      AVREMO CIRCA 20/30 MINUTI DI TEMPO LIBERO A CUI DEDICARSI A CIO’ CHE VOGLIAMO………………………………………..  
      COLGO L’OCCASIONE PER FARVI NOTARE LA VELOCITA’ E LA SICUREZZA DI QUESTO METODO
      CONFRONTATE QUESTO CON IL TERZO METODO E NOTERETE CHE CON UN SOLO PASSAGGIO, OSSIA IL COMANDO DATO AL TERMINALE, FACCIAMO IN UNA SINGOLA OPERAZIONE TUTTI I VARI STEP DESCRITTI SULL’ ALTRO METODO.
      DETTO QUESTO, MOLTO IMPORTANTE E’ SOTTOLINEARE CHE COSI’ FACENDO EVITEREMO ERRORI  DI DISTRAZIONE RIGUARDO AI PASSAGGI O FRAINTENDIMENTI.

      Potete adesso passare ad installare il bootloader Clover sulla vostra usb.
      *NOTA*:
      Avendo usato questo metodo l'installazione si dividerà in due fasi, perciò dopo il primo riavvio e necessario far partire nuovamente l'installer, selezionare lo stesso disco senza formattarlo.
      Finita questa ulteriore fase , l'installazione sarà terminata
      =========================
      METODO "MANUALE"....  (lascio per futura memoria-Compatibile fino a 10.12)
      ==========================
      Bootloader
      **Nota:** Installazione in UEFI  dipenderà dalla scheda madre in vostro possesso, quindi se non supporta tale opzione , il bootloader dovrà essere installato in  modalità Legacy.
       Vi invito, qualora non sapeste questa informazione, a recarvi nel sito ufficiale del produttore e controllare le informazioni a riguardo
      Fatto questo dobbiamo installare  Clover sulla usb.
      A seconda del tipo di Bios o al tipo di installazione che vogliamo fare UEFI o Legacy avremo ovviamente configurazioni diverse in questa fase.
      Lanciate il pkg.
      Immagine 

       
      Cambiate la destinazione di installazione ad USB oppure Install Mac_OS_X (a secondo del tipo di creazione eseguita)
      Successivamente clicchiamo su "Ad Hoc"
      Per Installazione UEFI
      Mettete i flag   : Installazione solo per avvio UEFI
                               : installare Clover nella ESP
                               : Driver64UEFI  AptioMemory --> (consigliato) 
                               : Driver64UEFI  ApfsDriverLoader --> (consigliato) --> sostituisce l'uso del driver apfs.efi
                               : Selezionate l'altri driver come da successiva immagine,
       
      *Nota: Altri driver che si possono usare  al suo posto  sono:
       informazioni 
       
      Proseguite con l’installazione.
      Immagine 
      ** Ricordate che avrete accesso a questa cartella dopo aver montato la partizione EFI**
      ===========================
      Per installazione Legacy
      Immagine 
      ===========================
      Impostazione per config.plist:
      Con clover configurator “montate” la partizione EFI della usb.
      1) Per fare questo nel menù di sinistra, cliccate su “Mount EFI”
      2) individuate la partizione relativa alla vostra usb, a questo punto montiamo la relativa partizione EFI  selezionando l’apposito pulsante “Mount Partition”
      Immagine 
      3) Successivamente cliccate su “Open Partition”.. recatevi in EFI/Clover ed aprite il config.plist
      4) Sezione ACPI: Disabilitate tutti i fix sia del menù 1 che del menù 2
      Immagine 
      5) Sezione BOOT: Sole se si sta installando Yosemite mettete il flag su kext-dev-mode=1
      Immagine 
      6) Sezione RT Variables: Se si sta installando El Capitan oppure Sierra, aggiungere i valori: BooterConfig= 0x28, CsrActiveConfig= 0x67
      Immagine 
      7) Sezione System Parameters: Su inject kext mettete YES
      Immagine 
      ===========================
      Nota: Su El Capitan, è stato introdotto SIP (System Integrity Protection)
      Info:
      ===========================
      Recatevi in EFI/Clover/kext/10.x 
      X= alla versione di osx che state installando. Per esempio se installerete Yosemite dovrete recarvi nella cartella 10.10, con El Capitan in 10.11….ecc
      Se non ci fosse tale cartella, createla e nominatela voi a “modo”.
      Copiatevi all’interno FakeSmc.kext
      *Nota se venite già da altre vostre configurazioni, oltre kext sopra citato ,potete mettere gli altri necessari per il vostro hardware
      Stessa cosa se avete DSDT e/o SSDT potete copiarli in EFI/Clover/Acpi/Patched
      Immagine 
      
      Per High Sierra:
      Scaricare il driver apfs.efi a fine guida, collocarlo:
          --> EFI/clover/Driver64UEFI se stiamo usando UEFI
      --> EFI/Clover/Driver64 se stiamo usando Legacy
       
      Per chi volesse continuare ad usare HFS vi rimando a questo post:
        Come installare High Sierra in HFS direttamente dalla usb  
      Utenti Laptop:  Nel 99% è obbligatorio disattivare la grafica discreta Nvidia/Amd per installare questo nuovo osx
                                     Quindi aggiungete --> SSDT-Disable_DGPU.aml.zip
                                     in EFI/Clover/acpi/Patched della usb
      --------------------------------------------------------------------
      Per Mojave:
      Scaricare il driver apfs.efi per 10.14 a fine guida, collocarlo:
          --> EFI/clover/Driver64UEFI se stiamo usando UEFI
      --> EFI/Clover/Driver64 se stiamo usando Legacy
      Versione di clover non antecedente a V_4015
      Volete usare HFS?
      E' possibile fare un installazione diretta su altro disco o partizione, nel caso può essere usato anche per effettuare aggiornamenti...
      nel caso guardate...
       Mojave in HFS 
       Oppure direttamente da usb  
       
      Fatto questo avrete la vostra USB bootable per installare OSX.
      ………Non scordatevi Fakesmc.kext da mettere nella relativa cartella…. senza il quale non farete mai il Boot......
      *NOTA: se usato il terminale per la creazione della usb, l'installazione si dividerà in due fasi, perciò dopo il primo riavvio e necessario far partire nuovamente l'installer, selezionare lo stesso disco senza formattarlo.
      Finita questa ulteriore fase , l'installazione sarà terminata
      **NOTA** Se avete processori Broadwell,Skylake o Kabylake...usate FakeSmc.kext e relativi sensors che trovate all'interno del secondo pacchetto.. (potete usarlo anche sui precedenti senza problemi, essendo una versione più aggiornata ha ulteriore supporto per le cpu più recenti)
      Update: Fakesmc e sensors versione 6.26
      Post installazione... post #2           
       Buon Hack….. 
      Aggiornamento:Install_Mac_OS_X.command.zip (compatibile da 10.10 a 10.12)
