Ubuntu 26 MacBook Pro A1706 (13,2)

This repo is dedicated to explanation of the MacBook Pro A1706 config for Ubuntu 26.

WiFi Fix for Broadcom 43602

Just after installation I have noticed that the wifi does see 2,4 GHz networks, however cannot connect to any of them. It did not recognize any of the 5GHz networks.

Fix:

download both files

brcmfmac43602-pcie.bin
brcmfmac43602-pcie.txt

copy files to /lib/firmware/brcm

sudo cp brcmfmac43602-pcie.* /lib/firmware/brcm/

reload brcmfmac

sudo modprobe -r brcmfmac_wcc brmcafmac
sudo modprobe brcmfmac

Restart NetworkManager

sudo systemctl restart NetworkManager

outcome

Now you should be able to connect to 5GHz networks, still network strength is to be fixed and cannot connect to 2,4GHz, however 5GHz is fully OK for me :)

Audio fix

Below instruction worked for me after first attempt. After the reboot I could finally liesten to music.

git clone https://github.com/davidjo/snd_hda_macbookpro.git
cd snd_hda_macbookpro/
sudo ./install.cirrus.driver.sh
sudo reboot

Touchbar drivers - build and install

Import of Ronald Tschalär's Macbook T1 drivers for the touchbar, ambient light sensor, and webcam, for kernel v7

Download the zip file with the code
mbp-t1-touchbar-driver-main.zip
unzip it and then:

1. Build

From the repository root:

cd /mbp-t1-touchbar-driver-main
make

2. Install

Install the modules to the kernel module tree:

sudo make install

If your system uses initramfs, update it after installation:

sudo update-initramfs -u

3. Deploy supporting files

Copy the helper script, service unit, and blacklist to the proper system locations:

sudo cp apple-ib-touchbar-rebind.sh /usr/local/bin/
sudo cp apple-ib-touchbar.service /etc/systemd/system/
sudo cp apple-ib-touchbar-blacklist.conf /etc/modprobe.d/
sudo chmod +x /usr/local/bin/apple-ib-touchbar-rebind.sh

4. Configure module blacklist

The blacklist file prevents conflicting HID/ALS drivers from loading automatically (already copied in step 3.):

blacklist hid_sensor_hub
blacklist hid_sensor_als
blacklist apple_ib_als

5. Enable the systemd service

Reload systemd, then enable and start the service:

sudo systemctl daemon-reload
sudo systemctl enable apple-ib-touchbar.service
sudo systemctl start apple-ib-touchbar.service

The service is defined as Type=oneshot, so it runs once at boot and finishes.

6. How the helper script works

The script performs these steps:

1. Removes conflicting modules if loaded:
   • hid_sensor_hub
   • hid_sensor_als
   • apple_ib_als
2. Loads apple_ibridge
3. Loads apple_ib_tb
4. Rebinds the USB device on bus 1-3

This ensures the touch bar receives the correct HID interface and avoids the 0302 conflict.

7. Manual testing

Run the helper manually when needed:

sudo /usr/local/bin/apple-ib-touchbar-rebind.sh

If the touch bar is already working, this is useful after rebuilding and reinstalling the modules.

8. Verify status

Check service status with:

systemctl status apple-ib-touchbar.service

A healthy state should show:

• Loaded: loaded ... enabled
• Active: inactive (dead)
• status=0/SUCCESS

Also verify the loaded modules:

lsmod | grep -E 'apple_ib_tb|apple_ibridge|apple_ib_als|hid_sensor_hub|hid_sensor_als'

Expected result:

• apple_ib_tb loaded
• apple_ibridge loaded
• hid_sensor_hub, hid_sensor_als, apple_ib_als not loaded

9. Notes

• If you rebuild the drivers, repeat make, sudo make install, and optionally sudo update-initramfs -u.
• If the touch bar stops working after a reboot, run the helper script again.
• If you want to restore ALS support, remove or modify the blacklist file.

Problems with wakeing up from the suspended state

I have been having an issue with my laptop freshly after installation of the system. Whenever I suspended it/closed the lid, it's been taking a lot of time to wake up (2 minutes of black screen) and after the screen went live, I was unable to type my password. I had to force shutdown each time by holding power button.

This was apparently caused by NVME not properly waking up.\ Fixed it following this procedure:

Create a service which starts up on boot

sudo nano /etc/systemd/system/fix_sleep.service

In the file, add these lines:

# systemd oneshot service to set sleep boolean on Apple Macbook Pro disks
# Original by Pier Lim. Posted at https://kerpanic.wordpress.com/2018/03/13/apple-keyboard-get-function-keys-working-properly-in-ubuntu/

[Unit]
Description=Job that disables sleep from stopping nvme hardware on MBP
    
[Service]
ExecStart=/sbin/fixsleep
Type=oneshot
RemainAfterExit=yes

[Install]
WantedBy=multi-user.target

Save the changes (CTRL+O->Enter) and exit (CTRL+X)

Now, before adding below lines please check your NVMe drive data by running:

lspci | grep -i nvme

I have got something like:
01:00.0 Mass storage controller: Apple Inc. S3X NVMe Controller (rev 12)
If your nvme location is different, you need to adjust it in the script below.

Next create /sbin/fixsleep script

sudo nano /sbin/fixsleep 

Content:

#!/bin/bash
/bin/echo 0 > /sys/bus/pci/devices/0000\:01\:00.0/d3cold_allowed

Save the changes (CTRL+O->Enter) and exit (CTRL+X)

Make the file executable

sudo chmod +x /sbin/fixsleep 

Now you can reload daemon and run your service to test whether everything works as expected:

sudo systemctl daemon-reload
sudo systemctl start fix_sleep.service

Thanks to this now my laptop wakes up from the syspension within 10 seconds and I am able to sign in and continue my work.
