Linux 6.15 kernel brings major Apple Silicon improvements, including Touch Bar support, PCIe/USB-A fixes, and audio patches for M1/M2 Macs. Learn about the latest Asahi Linux developments for Apple hardware.
The upcoming Linux 6.15 kernel is set to introduce significant advancements for Apple Silicon Macs, thanks to the relentless efforts of the Asahi Linux project.
This update includes critical drivers and patches that enhance compatibility with M1 and M2 MacBook Pros, paving the way for broader Linux adoption on Apple hardware.
Key Features in Linux 6.15 for Apple Silicon
1. Touch Bar & Display Controller Support
The Apple Display Pipe (ADP) driver and Z2 touchscreen digitizer are now part of the upstream kernel, enabling Touch Bar functionality on:
M1 13" MacBook Pro
M2 13" MacBook Pro
This breakthrough allows Linux users to leverage Apple’s proprietary hardware features seamlessly.
2. PCIe & USB-A Support for M2 Pro Devices
The T6020 SoC (M2 Pro/Max) now has PCIe controller support, which is crucial for:
USB-A ports on M2 Pro Mac mini
WiFi & Bluetooth functionality
However, WiFi/BT support still depends on the System Management Controller (SMC), which is still under development.
3. Audio Enhancements & Speaker Amp Fixes
Linux 6.15 introduces patches for:
TAS2764 & TAS2770 amplifier chips (used in Apple Silicon Macs)
Basic audio support for Apple-specific variants
Ongoing Challenges: Microphone Support & M2 Pro Issues
While microphone support has been added for most M1/M2 MacBooks, the M2 Pro/Max models face compatibility issues due to differences in the Always-On Processor (AOP). The Asahi team is actively working on a fix.
"There is nothing more permanent than a temporary solution."

Future Roadmap: M3 & M4 Support Still a Work in Progress
Despite progress with M1/M2, Apple M3 and M4 Macs remain a major challenge. Full Linux support will take time, but the Asahi team continues to push forward.
