I've got a fully working install of Catalina 10.15.5 using OpenCore 0.5.9 and I've managed to get everything working perfectly. It's my first PC Build ever (Let alone Hackintosh) so I'm pretty pleased that I've managed to get everything up and running so far, including Thunderbolt 3 (with hotplug), Sidecar, onboard HDMI Audio, Wifi/BT pairing across both OS (Windows 10 and MacOS). The only thing that now bugs me is the time taken to boot from the Opencore picker to my login screen. It's not super slow by any means, but with my specs I believe it should be faster. Here is what I'm running:
Windows boot is pretty sharp - Usually under 10secs. MacOS on the other hand usually is in the region of ~70secs. When I first installed Catalina it would boot super quick, but it's gotten more and more sluggish over the last few weeks. Is there anything I can do to speed it up? I can attach my EFI if needed.
spero tu mi possa aiutare ,perche' non riesco piu' a far partire i miei 2 ssd 850 samsung sui quali highsierra funzionava perfettamente da 1 anno e non ce' maniera di farlo ripartire .unica cosa e' che riesco ad arrivare alla console dell'istaller e ho tentato varie volte di ripristinare da una time machine che ho salvato su un altro disco usb .
il mio sistema e' un asus p5qd turbo ed e7500 dual core . grafica gtx1050 chr funzionava con accelerazione e webdriver nvidia .audio voodoo 282. e boot clover che e' sempre stato il 5103 che poi ho aggiornato a 5120 proprio il giorno prima che succedesse il fattaccio .quel giorno ho aggiornato dal sito apple la comboupdate 10.13 .6 da 10.13.4 .e qui al riavvio boom niente diski in clover nn li visualizzava piu .ora sciacciando f3 visualizzo il preboot e lssd con highsierra aggiornato ma arrivato alla console andava in reset loop .
a questo punto riesco a ripartire togliendo l'accelerazione .e installando i nuovi webdriver di nvidia aggiornati all 10.13.6 .
al riavvio non parte piu' con accelerazione e sempre problema in clover dei diski ma riuscivo a partire con f3 e preboot .
ora decido di installare da time machine e tornare alla versione 10.13.4 del giorno prima ..e al riavvio niente piu dischi ne preboot .sono fermo a questo punto ..riesco solo a far partire installer ma nn so i comandi da dare in terminal per aggiustare le cose . ho anche linux su un altro notebook. ti ringrazio anticipatamente per l'aiuto .
So, here's what i think clover do when it patch ati framebuffer, first it read a cached kext, then it search the original hex value of the connector, then it changed the value with the new one. Is it correct? now, here's what i find confusing... let's say that i want to patch AMD7000Controller.kext, in that kext, i want to patch "AJI" framebuffer with a new value, so clover try to find the hex value of "AJI" connector then replace it with the new one, simple right? but when i search the AMD7000Controller binary file for other framebuffer, some of them didn't exist in the binary, for example, i tried to patch "Ramen" framebuffer, from various source, it said that:
Ramen (6) @ 0xeba70
LVDS, HDMI, DP, DP, DP, DP
So i open a hex editor and search for:
but, it turns out that hex editor couldnt find that hex value in AMD7000Controller,
most of the framebuffer exist in the AMD7000Controller, but some doesnt, If this is the case, then, where does clover find the original framebuffer to be patched? am i missing something?
Lenovo T460 macOS with Clover Guide
Latest Release on GitHub (July 2020)
Updated to Clover r5120
Updated Lilu based kexts - Lilu, ALC, WEG
Various Tweaks over Last months
The main branch in my github repo is a complete Clover ESP (/EFI) bundle and kext pack for the Lenovo T460. The current file bundle seems to work on Sierra, HighSierra, Mojave and Catalina. There is an OpenCore branch in the repo as an alternative to Clover. This guide was developed for a Clover implementation. But the thread has evolved to include discussion of both Clover and Opencore for these systems: T460 and T470 family of ThinkPads.
Full Clover file set - config.plist etc.
Includes all custom kexts
Includes custom DSDT/SSDT scripts and patches
The zip bundles are posted to GitHub: https://github.com/tluck/Lenovo-T460-Clover/releases
Caveat: The T460 systems used here was configured with: i5-6300U, Intel HD Graphics 520, 1920x1080 touch screen. If you have a different system model, then extract the ACPI files and use the included scripts to create a set of files consistent with your system type and BIOS version. See below for details.
Credits: RehabMan, Shmilee, vusun123, TimeWalker, Mieze from which, much of their work and help is/was was used to get the T460 to this point.
Devices and aspects working:
Ethernet - Intel I219LM is enabled via IntelMausiEthernext.kext
WiFi/BT - substitute the Intel WiFi/BT with a compatible Broadcom or Atheros chip
Audio - ALC293 codec implemented via AppleALC.kext (the old AppleHDA_ALC293 and CodecCommander kexts are not needed)
PS2 - ClickPad + TrackPoint + all 3 buttons - using a modified VoodooPS2Controller to support new layouts - and added some custom Fn key maps based on 440/450 dsdt
USB - implemented via custom SSDT + USBInjectAll kext. All USB3/USB2 ports are intel-based and work - 3 external USB and internal Camera, BT, etc
Sleep/Wake - the sleepwatcher package and custom sleep/wake scripts are used to help with sleep/wake for BT and PS2 devices.
Note: have not tried to implement the SD card reader - no driver found.
