Here is the log file. Please help :(

Thanks!

Edit:

I tried almas, ecos-hj and BrianValente branches but neither of their fixes worked for me.

i have same problem this driver is not working on kernel 6 version

RamtinKosari avatar Aug 28 '24 18:08 RamtinKosari

i downloaded and used the almas version for linux kernel 6.1.0-25 and was able to get it to compile after changing 2 lines of code that errored i solved apple-ib-tb.c:949 by adding default: break; on line 956-957 after case HID_FEATURE_REPORT: report_info->report_type = 3; break; on 954-955 i was only given one other error apple-ibridge.c:905 which i fixed by changing void in static void appleib_remove(struct acpi_device *acpi) on 846 to int and return; on 852 to return 1;

after compilation and reboot, i needed to run sudo echo '1-3' > /sys/bus/usb/drivers/usb/unbind && sudo echo '1-3' > /sys/bus/usb/drivers/usb/bind to get the touchbar to work as recommended here https://github.com/roadrunner2/macbook12-spi-driver/issues/42#issuecomment-602160740

Is this repository being regularly merged to linux kernel?

Hey, I got the driver running on my Ubuntu 24.04 install on a mbp13,2 on kernel 6.8 for a while, with the patches from this issue aswell as the macbook-quirks.service from issue #42. Recently I upgraded to kernel 6.11 and I cant get the driver to work anymore. I fixed some more compile errors, but even after that the touchbar wont turn on anymore. Will upload my fixes and dmesg logs later, maybe someone can help 🍻

Thank you for your efforts. I'm trying to bring a MacBook 8,1 back to life. That model had a very bad reputation due to over heating. Surprisedly, one can get a marvelous user experience with that machine and ubuntu. It works really fast and fluid and no overheating at all. Sadly, suspension mode, keyboard+touchpad, bluetooth and audio (only jack output is working) are preventing me from making a daily use of that machine.

Please check my fork https://github.com/jussike/macbook12-spi-driver/commits/touchbar-driver-hid-driver/

It can be compiled against newer kernel, 6.8 at least. You'll not need to compile applespi at all because it's already merged to mainline. It's removed on my fork.

fails to compile on arch, kernel 6.13.7, mbp 14,3. please advice

Hello. I have a macbook 8,1, running ubuntu 24.04 with the 6.8 kernel. My keyboard and trackpad sometimes do work upon rebooting, and sometimes do not. I am trying the touchbar-driver-hid-driver/ branch. I get the same error as I did with the original driver from the main branch. Here is what I see:

Hello. I have a macbook 8,1, running ubuntu 24.04 with the 6.8 kernel. My keyboard and trackpad sometimes do work upon rebooting, and sometimes do not. I am trying the touchbar-driver-hid-driver/ branch. I get the same error as I did with the original driver from the main branch. Here is what I see:

Any ideas?

Seems that you are using wrong branch or commit. See the current hash with command $ git rev-parse --short HEAD It should give 774b401

jussike avatar Mar 20 '25 10:03 jussike

Please check my fork https://github.com/jussike/macbook12-spi-driver/commits/touchbar-driver-hid-driver/ It can be compiled against newer kernel, 6.8 at least. You'll not need to compile applespi at all because it's already merged to mainline. It's removed on my fork.

fails to compile on arch, kernel 6.13.7, mbp 14,3. please advice

I have no time to install 6.13 today but I fixed compiling against 6.11 https://github.com/jussike/macbook12-spi-driver/commits/touchbar-driver-hid-driver-linux-6.11

And I made a fix for 6.13 also but I didn't try even to compile it. Please try: https://github.com/jussike/macbook12-spi-driver/commits/touchbar-driver-hid-driver-linux-6.13

@jussike @tkalant use the patched version from almas https://github.com/almas/macbook12-spi-driver in combination with the macbook-quircks.service from issue #42. worked for me on 6.8

arag0re avatar Mar 20 '25 10:03 arag0re

sadly maintianer is afk and wont merge changes into the repo so u need to find the patched forks for yourself

Hello @jussike Thank you for responding. You were right. I cloned the correct repository, ran the installation, and it seems like it went without a problem, but I keep having the same issue. After rebooting sometimes the keyboard works and sometimes not - here is what I see after installing:

I also installed kernel 6.11, changed to that kernel on grub when booting, and ran the installation from the 6.11 branch you made yesterday. I made sure I am on the c0cf3bf commit. That did not work, here is what I saw:

@arag0re Thank you. I tried this version from almas with 6.8 kernel, it did not work for me. Kept getting the same error as before. And it seems to me (might be wrong) that the macbook-quirks.service is related to the touchbar, which my macbook does not have.

tkalant avatar Mar 21 '25 07:03 tkalant

After rebooting sometimes the keyboard works and sometimes not

My fork has no keyboard/touchpad driver bc it's a part of upstream kernel (applespi). Perhaps you should report the upstream driver maintainer. You may use my fork as a touchbar driver if you have any on your device.

Consult /var/lib/dkms/applespi/0.1/build/make.log for more information.

You didn't attach the make.log

I didn't realize your fork does not have a driver for the keyboard. there is no touchar on my device so I guess I only have the original repository to try (roadrunner) as an option, which did not work. Thank you anyway.

EDIT2: I SOLVED IT! I'LL LATER POST THE SOLUTION!

Hi everyone,

I'm trying to get Linux fully working on my MacBook Pro 13,2 as a replacement for macOS — I'm really tired of macOS, but the hardware is still great, so I'd love to keep using this machine.

I've managed to get both Wi-Fi and sound working, but I'm still stuck on getting the Touch Bar to function. I've tried various versions of the applespi/apple_ibridge modules, including several branches like the 6.11/13 fix versions, but no luck so far.

Currently, I'm running Kubuntu 22.04 with the 6.8.0-59 kernel. The modules install without errors and appear to load correctly (outputs attached below), but the Touch Bar remains completely off — no response at all. I’ve tried various workarounds, but nothing has helped.

Interestingly, I had it working in the past with Ubuntu 18, but now it seems much harder to get it going.

For installing I completely wiped the disk after making a EFI partition wipe, to retain the EmbeddedOS part needed by the touchbar, and in fact if I boot in macOS recovery mode (option+r) the touchbar works, so I think it is not missing the firmware.

I also tried removing usbmuxd to rule that out, but it didn’t help.

Also tried to use the touchbar-reset.service and this:

echo '1-3' | sudo tee /sys/bus/usb/drivers/usb/unbind
echo '1-3' | sudo tee /sys/bus/usb/drivers/usb/bind

and get his in journalctl:

EDIT2: I SOLVED IT! I'LL LATER POST THE SOLUTION!

Great! Please post your solution.

Problem Description:

The apple-ibridge driver system, particularly the apple-ib-tb sub-driver for the Touch Bar, relies on two distinct HID reports/interfaces exposed by the Apple iBridge chip (USB VID:05AC, PID:8600) under its first USB configuration:

  1. An interface/report for Touch Bar Mode control (ESC, Fn keys, Special keys).
  2. An interface/report for Touch Bar Display control (brightness, on/off).

Analysis of lsusb -v -d 05ac:8600 for Configuration 1 (default) shows:

  • USB Interface 2: bInterfaceClass 3 (HID), bInterfaceProtocol 1 (Keyboard), wDescriptorLength 83.
  • USB Interface 3: bInterfaceClass 3 (HID), bInterfaceProtocol 1 (Keyboard), wDescriptorLength 634.

The apple-ibridge-hid driver (the HID muxer component of apple-ibridge.c) correctly probes the HID device created from USB Interface 2. The apple-ib-tb sub-driver's probe function is then called with this hid_device, and it successfully populates its mode_info structure by finding the HID_USAGE_MODE (0xff0004) in application 0x10006.

However, USB Interface 3 (which is expected to provide the HID_USAGE_DISP for disp_info) is claimed by the kernel's generic hid-sensor-hub driver. This is evidenced by:

  • dmesg logs showing hid-sensor-hub binding to a hid_device (e.g., 0003:05AC:8600.000X where X corresponds to Interface 3, often seen on /input3).
  • ls -l /sys/bus/usb/devices/.../1-3:1.3/Y.Y.Y.Y/driver pointing to hid-sensor-hub.

As a result, apple-ibridge-hid is not given a chance to probe the hid_device associated with USB Interface 3. Consequently, the apple-ib-tb sub-driver's probe function is not called for this second required interface, tb_dev->disp_info.hdev remains NULL, and the condition if (tb_dev->mode_info.hdev && tb_dev->disp_info.hdev) is never met. This prevents the full initialization of the Touch Bar, including setting its initial mode/display state, registering the input handler for Fn key events, and creating sysfs attributes. The Touch Bar remains non-functional.

Workaround Implemented (via udev rule):

To resolve this, a udev rule was created to forcibly unbind hid-sensor-hub from the hid_device associated with USB Interface 3, and then attempt to re-trigger a driver probe for that hid_device, allowing apple-ibridge-hid to claim it.

The effective udev rule in /etc/udev/rules.d/98-apple-ibridge-custom.rules:

ACTION=="add", SUBSYSTEM=="hid", ENV{HID_ID}=="0003:000005AC:00008600", ENV{HID_PHYS}=="*input3", ATTR{driver}=="hid-sensor-hub", \
  RUN+="/bin/sh -c '/usr/bin/logger -t UDEV-IBRIDGE Unbinding %k from hid-sensor-hub; echo %k > /sys%p/driver/unbind; /usr/bin/logger -t UDEV-IBRIDGE Unbound %k. Attempting to trigger drivers_probe; echo %k > /sys/bus/hid/drivers_probe; exit 0'"

Explanation of the udev rule:

  • ACTION=="add", SUBSYSTEM=="hid": Triggers when a HID device is added.
  • ENV{HID_ID}=="0003:000005AC:00008600": Matches the iBridge HID device by its vendor/product ID (case-corrected).
  • ENV{HID_PHYS}=="*input3": Matches the physical path ending in /input3, which corresponds to USB Interface 3.
  • ATTR{driver}=="hid-sensor-hub": Ensures this rule only runs if hid-sensor-hub is the driver currently bound (or about to bind) during the add event.
  • RUN+=...:
    • Logs the attempt.
    • echo %k > /sys%p/driver/unbind: Unbinds hid-sensor-hub from the specific HID device (%k is the kernel name of the HID device, e.g., 0003:05AC:8600.000X). %p is its sysfs path.
    • echo %k > /sys/bus/hid/drivers_probe: Triggers the HID core to re-probe drivers for the now-unbound HID device.

This workaround allows apple-ibridge-hid to subsequently probe the HID device from USB Interface 3. The apple-ib-tb sub-driver's probe is then called a second time, successfully populating disp_info, leading to full Touch Bar initialization and functionality.

Proposed Long-Term Solution (Driver-Level Change):

While the udev rule provides a functional workaround, it's not ideal as it relies on specific sysfs paths and external configuration. A more robust solution would involve changes at the driver level.

The apple-ibridge.c module should ideally register a struct usb_driver in addition to its ACPI and HID muxer drivers. This usb_driver would:

  1. Have a usb_device_id table that specifically matches both USB Interface 2 and USB Interface 3 of the iBridge device (VID:05AC, PID:8600). This match could be based on VID, PID, and bInterfaceNumber.

    // Example ID table entries for the usb_driver in apple-ibridge.c
static const struct usb_device_id apple_ibridge_usb_table[] = {
    { USB_DEVICE_INTERFACE_NUMBER(USB_ID_VENDOR_APPLE, USB_ID_PRODUCT_IBRIDGE, 2) }, // For Interface 2
    { USB_DEVICE_INTERFACE_NUMBER(USB_ID_VENDOR_APPLE, USB_ID_PRODUCT_IBRIDGE, 3) }, // For Interface 3
    { } /* Terminating entry */
};
MODULE_DEVICE_TABLE(usb, apple_ibridge_usb_table);

    (Note: USB_DEVICE_INTERFACE_NUMBER might require specific kernel versions or a custom macro if not standardly available for this exact purpose in usb_device_id.) Alternatively, a more general USB_DEVICE(USB_ID_VENDOR_APPLE, USB_ID_PRODUCT_IBRIDGE) could be used, and the USB probe function would then check interface->cur_altsetting->desc.bInterfaceNumber to differentiate.

  2. Implement a USB probe function. This function would be called by the USB core for each matching USB interface.

    • Inside this USB probe function, the driver would explicitly tell the USB core that this interface should be handled by the HID subsystem, and specifically by its own apple-ibridge-hid driver, or it could directly interact with the HID core to register the hid_device.
    • By claiming the USB interfaces directly, apple-ibridge would have precedence over generic drivers like usbhid (which then delegates to hid-sensor-hub or hid-generic). The USB core typically prefers more specific driver matches.

  3. Coordination: The apple-ibridge ACPI driver would still be responsible for overall device power management (SOCW) and MFD cell creation. The new USB driver component would handle the binding to the specific USB interfaces that expose HID functionality, ensuring they are passed to the apple-ibridge-hid muxer.

This approach would make the driver self-contained and less reliant on udev rules to fight for interface control, leading to a more stable and predictable initialization sequence for all necessary Touch Bar components.

@scuty2000 Great work, thank you.

I'm evaluating Cachyos (linux 6.15) on my MBP. Unfortunately neither of workarounds (via udev or via systemd service) works. So it really looks like we need a patch to the driver. Maybe we can try to get it to upstream if it works well? Are you able to test your driver level ideas?

Macbook Pro 14,3 running arch, kernel 6.15.7-arch1-1. Also attempted under linux-zen (same version). The driver builds properly, but I'm not seeing anything that suggests the driver is enumerating the device properly.

cc @jussike

Update: I was able to get this working properly after a full reinstall of MacOS, and leaving the EFI partition intact after install (mounted under /boot/efi). After installing jussike's module, I did the bind/unbind command, and the touchbar appeared. The only issue that stands out appears to be a driver/hardware quirk - I have to unplug all my USB devices at boot-time for the touchbar to appear. Once booted and the touchbar is available, I can connect my devices. The Mac USB hardware is incredible touchy/flaky and devices sometimes take a long time to enumerate, assuming they don't issue warnings or fail outright.

I wrote a quick MacOS install guide to remind myself how I installed Arch for touchbar use, hopefully someone finds it useful.

you sir are a genius. For 2 weeks I had been trying to enable the touchbar on an 13,2 and it just wouldn't work. Your udev rule made it light up for the first time!

thanks a lot, -Christian
