Hi @abhisek176 , I've updated the article https://nixaid.com/linux-on-macbookpro/
Could you please try booting the https://files.nixaid.com/ubuntu4mac.iso ? (sha256: a77086a4aadbfd5b29e86232a9e24aba0f3a963af064e3c961adae8e9f8d2682)

I've added the evdev:name:Apple SPI Touchpad:dmi:*:svnAppleInc.:pnMacBookPro15,4:* line to /etc/udev/hwdb.d/61-evdev-local.hwdb file there. Cannot promise that it will help, but let's see.

Let me know whether the keyboard, touch pad, touch bar are working.

Hi @arno01, I tried the new ISO. The bootable flash drive did not show any sign of trackpad or keyboard movement. I tried installing but the installation got failed with an error https://drive.google.com/open?id=1_LlxRSGJZbKVX_pMErFjJQJs3OEj_AnR

@abhisek176 regarding the installer error, I have replied you via email since it's an off-topic.

The bootable flash drive did not show any sign of trackpad or keyboard movement.

I would presume the Linux kernel isn't recognizing some of the new MBP's 2019 hardware properly.
In this case there is no need to proceed installing it until we make keyboard & touchpad work.

Hook an external keyboard and you will be able to run some commands which might help in figuring out why the driver isn't working.

Please provide us with the output of these commands:

• xinput
• lspci -nnk
• dmesg -T | grep -i spi
• dmesg -T -l err
• cat /proc/interrupts

Hi @arno01: here are the outputs https://drive.google.com/open?id=1QtABl_PQE-dzv7O24glU9Ct7fFxGR5OJ. please have a look. kindly let me know if you need anything.

Abhisek was also sending me his syslog file, here is his HW:

DMI: Apple Inc. MacBookPro15,4/Mac-REDACTED, BIOS 1037.60.58.0.0 (iBridge: 17.16.12551.0.0,0) 11/14/2019

And he's got these errors as well:

Dec 30 12:41:33 ubuntu kernel: [    3.460140] applespi: loading out-of-tree module taints kernel.
Dec 30 12:41:33 ubuntu kernel: [   12.735839] applesmc: send_byte(0x10, 0x0304) fail: 0xff

I can't see SPI in his "xinput" output. Let's see if @roadrunner2 & @cb22 will have some more clues based on the logs provided by @abhisek176 .

@abhisek176 I've just found something that you might want to try.

There is a mbp15 branch https://github.com/roadrunner2/macbook12-spi-driver/tree/mbp15 - Work in progress driver for the touchbar and ambient-light-sensor on 2019 MacBook Pro's.

https://github.com/MCMrARM/mbp2018-bridge-drv -
A driver for MacBook models 2018 and newer, which makes the keyboard, mouse and audio output work.

Upd: And this thread might also be interesting as it discusses new MBP's 15,1/15,2 with the new T2 chip Dunedan/mbp-2016-linux#71

[roadrunner2]

@abhisek176 The MacBook Pro 15,* models do not expose an SPI based keyboard and trackpad, but instead a USB based one, i.e the driver here is only for 13,* and 14.* models. The links @arno01 provides above are correct: you need @MCMrARM's driver for the keyboard and trackpad, and my driver for the touchbar and ALS.

Hi @roadrunner2 . I used @MCMrARM driver and it worked. But I having problem with the touchpad clicks and taps. And also wifi seems to be not working in MBP15,4
