Enable multimedia keys, fan & LEDs control

Download and install YogaSMC-App-Release.dmg (both the pref-panel and app itself)
Open the app
Check the launch on login option

Use PrtSc key as Screenshot shortcut

Super useful shortcut that I wish I had it on my previous MBP. Default is ⌘⇧5.

Open SystemPreferences.app
Go under Keyboard > Shortcuts > Screenshots
Click on Screenshot and recording options field
Press PrtSc on your keyboard (it should came out as F13)

Use calibrated display profile

NotebookCheck's calibrated profiles. Not all panel are the same, final result may vary.

Run one of the following script in Terminal

for 1440p displays

cd ~/Library/ColorSync/Profiles; wget https://github.com/simprecicchiani/ThinkPad-T460s-macOS-OpenCore/raw/master/Files/DisplayColorProfiles/T460s_WQHD_VVX14T058J02.icm

for 1080p displays

cd ~/Library/ColorSync/Profiles; wget https://github.com/simprecicchiani/ThinkPad-T460s-macOS-OpenCore/raw/master/Files/DisplayColorProfiles/T460s_FHD_N140HCE_EAA.icm

Go under SystemPreferences > Displays > Colour
Select the profile

Add Apple Watch authentication to sudo

If you have an Apple Watch and you already replaced the built-in WiFi card, you could enable authenticating as sudo with you Apple Watch using pam-watch.

Download the latest ZIP file
Unzip, which by default creates a folder called pam-watchid-main.

Open Terminal and install it:

cd ~/Downloads/pam-watchid-main
sudo make install

Register the new PAM module for sudo:
- Edit /etc/pam.d/sudo
- Add a new line under line 1 (which is a comment) containing:
```
auth sufficient pam_watchid.so
```

That’s it. Now, whenever you use sudo, you have the option of using your Watch to authenticate.

Monitor temperatures and power consumption

Download and install HWMonitor
Check launch on login (optional)

Faster macOS dock animation

This enables auto-hide and speeds up the animation

Run the following script in Terminal

defaults write com.apple.dock autohide-delay -float 0; defaults write com.apple.dock autohide-time-modifier -float 0.5; killall Dock

Boot process tweaks

Setup hibernation and sleep

[Script](https://www.tonymacx86.com/threads/release-sleeponlowbattery-solb.264785) that performs auto sleep/hibernate at low battery.

Open terminal

Enter commands below one by one

Settings for AC:

sudo pmset -c standby 1
sudo pmset -c hibernatemode 0

Setting for battery:

sudo pmset -b standby 1
sudo pmset -b standbydelayhigh 900
sudo pmset -b standbydelaylow 60
sudo pmset -b hibernatemode 25
sudo pmset -b highstandbythreshold 70

Settings for all:

sudo pmset -a acwake 0
sudo pmset -a lidwake 1
sudo pmset -a powernap 0

To restore default system settings run

sudo pmset restoredefaults

Advanced energy management

acwake: wake the machine when power source (AC/battery) is changed (value = 0/1)

lidwake: wake the machine when the laptop lid (or clamshell) is opened (value = 0/1)

powernap: enable/disable Power Nap on supported machines (value = 0/1)

standbydelayhigh and standbydelaylow specify the delay, in seconds, before writing the hibernation image to disk and powering off memory for Standby. standbydelayhigh is used when the remaining battery capacity is above highstandbythreshold(has a default value of 50 percent), and standbydelaylow is used when the remaining battery capacity is below highstandbythreshold.

hibernatemode supports values of 0, 3, or 25. To disable hibernation, set hibernatemode to 0.
hibernatemode = 0 by default on desktops. The system will not back memory up to persistent storage. The system must wake from the contents of memory; the system will lose context on power loss.
hibernatemode = 3 by default on portables. The system will store a copy of memory to persistent storage (the disk), and will power memory during sleep. The system will wake from memory, unless a power loss forces it to restore from hibernate image.
hibernatemode = 25 is only settable via pmset. The system will store a copy of memory to persistent storage (the disk), and will remove power to memory. The system will restore from disk image. If you want "hibernation" - slower sleeps, slower wakes, and better battery life, you should use this setting.

thinkpad-t460s-macos-opencore's Issues

pre-release 6.2.1 and 6.2.2 intel wifi issues

In this pre-release, Intel Wi-Fi stops working (as in 6.2.1)

I transferred AppleBacklightSmoother.kext and SSDT-PNLF.aml to the 6.2 stable release there the brightness works fine as well as intel wi-fi kext

here is the log from release 6.2.2

02:211 01:914 OC: Prelinked injection AirportItlwm.kext (Intel WiFi driver) - Invalid Parameter
opencore-2020-11-02-090621.txt

Max speed of fan after shutdown.

When I turn off the laptop with the HDMI cable connected, the fan starts working at 100% (the laptop is turned off, only the fan is on), the problem disappears when I unplug the cable. Everything worked fine on Windows - any ideas?

Right Alt key turns into option key, but not cmd.

After updated the newest version of EFI folder, 0.5.8 opencore, the right Alt key turns into option key, it makes cmd+delete much harder than before.
And the two-finger-tap will not shows the rightmouse menu in most cases. I reversed the last dev version of VoodooPS2Controller makes it better.

Sreen Flicker on lower brightness

Hi. I successfully instaled macOS Catalina on my ThinkPad, everything works great except the screen. When the brightness is at maximum there is no flicker but at lower brightness, the flicker appears and I can't use the laptop it just hurts my eyes. Thank you in advance !

Upgrade to PCIe-NVMe SSD

Did you use SSD or PCIe NVME, i want to upgrade to PCie NVME that works with Catalina/BigSur. Can you please specify which Storage you used?

Slow Wi-Fi speed using Intel cards

I noticed that with my Intel 8260NGW card, whilst connected to a 5Ghz wifi, the max speed I was able to achieve were 50-60 MBit download and not much more than 20 Mbit upload.
This same card can handle 500+ MBit, as I've tested with a different OS on the same machine.
This might be caused by the immature kexts for Intel wifi, as my internet connection peaks out at 990 MBit-ish and my current wireless router can deliver up to 600 Mbit.

Automatic restart after shutdown problem

Compile SSDT-EXT1-FixShutdown.dsl into aml file from OC-little and inject into config.plist(ACPI-Add) file will fix this problem.

Can't Enable Apple Service

The line of code doesn't work: git clone https://github.com/corpnewt/GenSMBIOS && cd GenSMBIOS && ./GenSMBIOS.command

The error message says "Can't install the software because it is not currently available from the Software Update Server."

Choppy scroll?

Anybody else facing choppy scroll? Any known fix or it?
GPU acceleration is enabled and all other animations are smooth except scrolling and other trackpad gestures.

TouchPad freezing

Sometimes when i my laptop goes to sleep, when i wake it up after a while, the touchpad is not responding, it does not happen all the times but it does happen, the solution is use is restart the laptop, is there a way to solve this issue?

About changing 4k screen

Thank you for your work! Everything worked fine before I changed my screen from 1080p to 4k. The problem is that the display is ok in win10 but can not be lighted in macos. I have changed the framebuffer value but it can not work. I supposed there are some kernel crashes due to the value of dvmt preallote but I don't know how to solve this question, I am so grateful if you can help me with this question.

The battery displays the wrong parameters.

The battery displays the wrong parameters. Not with the remaining capacity. therefore there will be a situation where there is no low battery notification resulting in a sudden shutdown.

Installation Shut Down during Apple Logo

Hi!

I'm having troubles installing the MacOs on my ThinkPad t460s (Intel i5 and without special WiFi card)

I first tried creating the USB by using OpenCore 0.5.7 to download MacOs 10.14.5 and then replacing the OC folder with yours including the config file. But I couldn't boot the USB.

Then I did the same, but instead of copying the config file I used the sample config file from OpenCore 0.5.7 and then manually copied all the entries from your config file. I finally was able to boot.

After the first installation round completed my laptop rebooted and after the bar under the Apple logo got to approximately 30% my laptop suddenly shut down and after that every time I try to boot I get a screen saying that MacOs could not be installed.

Am I doing something wrong? How to properly create the installation USB?

How to generate SSDT-CPU

Hello,

You state that you can create your SSDT-CPU with the following steps...

Use CPUFriendFriend with desired LFM and EPP profiles which generates a modified plist for my Mac model
Use the plist from step 1 to generate ssdt_data with ResourceConverter script in CPUFriend.
Then merge the resultant ssdt_data from Step 2 with CPU-PLUG which is renamed to SSDT-CPU

However, I noticed the following...

CPUFriendFriend directly generates ssdt_data without going through step 2.
When I decompiled your SSDT-CPU, I see that it has content generated with Piker-Alpha’s ssdtPrGen. Did you mean to merge ssdt_data from CPUFriendFriend (or the ResourceConverter script) with the SSDT generated from Piker-Alpha’s ssdtPrGen? But then I read at many places that Piker-Alpha’s ssdtPrGen is not needed or obsolete these days. Can you please explain your usage.

CPUFriend SSDT generation

I want to do a custom CPU Power Managment,
After using this "git clone https://github.com/fewtarius/CPUFriendFriend; cd CPUFriendFriend; chmod +x ./CPUFriendFriend.command; ./CPUFriendFriend.command" and entering preferred values. ssdt_data.aml is not provided under results folder. Only Mac-473D31EABEB93F9B.plist is provided? Is there something i am doing wrong?

0.6.5 Laptop turns off when the first battery is discharged & #2 issue showing a warning that it will fall asleep, but it is just shutdown

Hi, the last pre-release still has battery problems
the laptop is working fine and HWmonitorSMC shows the real capacity of my battery (I have very tired batteries, but there are about 2500mAh) during the discharge, the capacity continues to fall and near about 40% of the charge knocks out the message that the laptop will soon fall asleep and at this point the percentage stop changing, and the HWmonitorSMC shows 2500mAh and after a while the laptop just turns off )=

it seems that at the moment of notification of a low capacity, the laptop ceases to see the real battery capacity

Wifi for Intel chip

Hi, sorry this is not an issue, but a request of implement a guide for intel wifi. Now with AirportItlwm.kext is it not necessary to use Heliport. Maps, Handoff , Airport are working (Big Sur and Catalina). It's very simple, just put AirportItlwm.kext in EFI and ADD Kernel in config.
What do you think about it?

How to modify CFG lock

This is not a issue, I just wonder how to extract the bios file, and find out where to unlock CFG and modify DMVT value?

Brightness Control issu, CPUFriend can't find Data, some errors at booting

hi,
first big thx for providing yours files.
i have t460s 6300u, 12Gb, 512GB, FHD with Touch, Dockingstation.

I used the EFI fron issu "Battery readouts not working" and mist of things are working fine.
So the first problem I notice is that my screen get completely at dark (off) at 75% level through key or the slider in the settings.
The second problem is that want to use CPUFriend to get the low freq. (800mhz I mostly use on battery) as without I get only 1300mhz. I followed your instructions and also search on other form but it don't work.
I always get an critical halt error. OC: Image Kexts\CPUF.. is missing for injected kext CPUFriend.kext (Frq.. data injector).
i´v tried with dataprovider kext and also apci but always get that error.
and the last problem is that I get some error at booting but its boot normal.

thx for your help in advance.

AirportItlwm on BigSur

Hello, this is not an issue but i just want to inform that AirportItlwm

not working corectly with Securebootmodel=Disabled at BigSur
But itlwm + Heliport working fine (exept slow speed on both methods)

Use dual monitor, must unplug/replug HDMI after sleep

Just setup a new hackintosh that is running great! Except for this one thing

When I came to my T460s this morning, it has initiated Display Sleep but I couldn't wake it up, even though the laptop was running fine otherwise.

I had to unplug/replug the HDMI cable from my laptop and then it woke up. That seems pretty specific – does anyone know how to fix this?

APFS Formatted Disks

I had a Clover setup working, which I recently removed to fully reinstall. I can boot into the MacOS installer using Opencore with the EFI provided and have used Disk Utility to format my SSD as APFS. When I get to the point in the installer where I need to choose the install volume it won't let me select the SSD and provides a message that says:

Your Mac needs a firmware update in order to install to this volume. Please select a Ma OS Extended (Journaled) volume instead

Have you attempted to install to an APFS formatted volume?

Bootcamp Doesn't Work

I tried to use bootcamp to partition my disk for both hackintosh and windows, since I only have one SSD and multi boot is dangerous according to online sources. However, I wasn't able to get it to work properly. Bootcamp indeed helped me divide my ssd to two partitions, but I couldn't access it on the boot screen and install windows while it does appear in disk utility and diskutil in terminal. Can anyone help me with this issue or help me with a secure way of dual boot?

kernel panic... Rebuild kext cache

I installed this boot loader to my T460s (cpu 6200u) But It had a kernel panic like the picture below...
How can i solve this problem?

Big Sur compatibility

Could you install big sur on t460s ?

Safari DRM not working

Netflix and prime video is not working in safari. I tried to add some shikigva boot-args, but didn't solved it. Do you have any solution?

Bluetooth and WLAN Adopter does not work...

I was using Bluetooth and wlan adapter well in the clover environment(RtWlanU1827, AirportBrcmFixup) but after switching to this open core, I used the existing kext but they didn't work at all.
Also, I don't know why batteries don't change at 1%.
Thank you

T460 1920 x 1080 version?

I've just purchased a non S version of the T460 and looking to install OpenCore and wondering if you know what needs to change in order from your EFI to work on the T460?

Do you think the MacBook13,1 profile would work the same? I'd obviously need to play with the RDM utility for the screen too.

Logged out when running resource extensive applications

Hello,
Thank you for the detailed instructions, i was able to install MacOS Catalina on ThinkPad T460s

I have been using it for a while but everytime i open up a resource extensive applications or processes the PC begins to overheat and logs itself out

Battery readouts not working

Battery readouts seems to not work OC 0.6.2 using ur EFI files. It's stuck on 1% and the status says battery is not charging.

Slow boot time when using 0.6.3 version

I tested using 0.6.3 version, but got very slow boot time, i.e. 1min15sec when using 0.6.3 compare to 20sec when using 0.6.0.
My device is T460s i5-6300u 8GB SSD SATA 256GB with BIOS version 1.3.4 dated 2018-03-22.

Another issue I faced is regarding battery management. Correctly showing and managing the battery consumption, but when it reaches 5% it shows a low battery warning then all of a sudden the system shutdown. Putting the charger afterwards, the system shows a 30% battery capacity, lighting indicator, but saying "Battery is not charging". A couple of restart fix this though.

Thanks.

Screen brightness levels t460s fullHD touch

The brightness levels switch incorrectly and the first half of the slider makes the screen completely black during the first sleep cycle of the laptop, it returns to normal and then breaks again = (
Also, the touch screen does not work, but it's not scary (=

my spec:
t460s
1920x1080 touch
12gb ram
i5 6300u
intel WLAN
intel 240GB SSD

CPUFriend

I see that you have removed both CPUFriend.kext and CPUFriendDataProvider.kext. My understanding is that you either use the CPUFriendDataProvider.kext or the SSDT-CPU.aml as generated by CPUFriendFriend but you always need CPUFriend.kext.

Are you suggesting that OpenCore does natively what CPUFriend.kext does and therefore not needed?

Mine is cori5 6300u. I have two errors ocs: no schema for protectcsm region. And no schema for shrinkmemory map

Batteries can't be recognized under windows booting by open core

Monitor resolution after Stop

I have 1920x1080 resolution and HDPI enabled

Low Trackpad sensitivity

Hey,

I have noticed that trackpad sensitivity is kind of low. What I mean is that sometimes it registers three finger swipe, sometimes it does not. I have to kind of press more firmly compared to a real mac.

I am not talking about "Tracking speed" which just makes your mouse move faster.

Is there anyway I could tweak this? I tried scavenging through various forums, but people only talk there about "Tracking speed" not the actual sensitivty of registering your fingers.

External display connections (HDMI and MiniDP)

Ciao Caro, the repo works fine except for external monitor. Neither HDMI nor mini DP works fine. HDMI just cannot output any signal while DP can only hold for seconds. Maybe it's the Catalina's fault?
