Native screen brightness is now in the Omarchy update channel for the 13-inch M4 MacBook Air. I just updated my Air and rebooted. The backlight driver started automatically, the panel reports 300 nits, and the brightness-key bindings are installed. No failed system services after the reboot. What’s new, and who helped get it here: • Native panel brightness, contributed by Jeff Hollis (github.com/jeffhollis). His work adds the driver and boot changes needed to control the panel’s backlight through Apple’s display coprocessor. He also supplied packaged-boot and physical-brightness test results from his Air. Brightness keys use 5% steps, Alt gives 1% steps, and Shift selects minimum or maximum. Dimming stops at 1%. Existing custom bindings are preserved. @kazuhidet caught the commented-out brightness examples that were preventing setup; that is fixed too. • DisplayLink components now come through omarchy-m4-update. The evdi kernel module and matching library are included. The earlier virtual-display test ran at 60 Hz and read frames back successfully. Testing a physical adapter with Synaptics’ DisplayLinkManager is still outstanding, and the manager is a separate install. Native video over USB-C and Thunderbolt still doesn’t work. • Signed integration-source archives, contributed by Rishvarma (github.com/Rish3666). Channel publications now include the integration sources and their exact commit. The final implementation gives each revision its own signed archive and handles interrupted uploads without overwriting another revision’s archive. • 15-inch M4 Air groundwork from @kazuhidet: the hardware survey, testing profile, boot devicetree and corrections to the power and firmware notes. He also identified a mini installer provisioning defect that has now been fixed in the source tooling. The 15-inch Air is still under development; this update does not make it a supported install. • M4 Mac mini survey and testing from github.com/mancix. Their hardware reports helped the board work, and their latest test exposed an HDMI failure after OS approval. That remains unresolved. New installations of the experimental mini kit are on hold, and no replacement mini installer was published today. • M4 Pro mini groundwork includes bootloader patches by CJ Damsleth, @kimzter (github.com/damsleth), adapted from his wallace project. The repository now has the board survey, initial devicetree and bootloader build recipe. That is preparation for hardware testing, not a working M4 Pro installer. The release passed 1,185 Linux tests, 25 macOS installer tests and 8 Rust tests. Public package hashes and signatures were checked after publication. My Air’s startup is now confirmed; physical brightness-key/OSD checks and suspend/resume are still outstanding on my machine. To update an existing Air installation: omarchy-m4-update Then restart once when prompted. The new versions are boot 1-14, backlight 1-1 and evdi 1.15.1-1. No reinstall is needed. Installer update 4 remains the latest Air installer and connects to the same channel. Thanks to the contributors for the code, hardware reports and testing. Please include your exact Mac model when reporting results or problems. github.com/Kb2uka/Omarchy-M4… #OmarchyMac #OmarchyLinux

Yes. Exactly this. #Omarchy #omarchyMac #vibecoding

If you're feeling frisky and want to test Omarchy M4 mac mini, there's a tester here with instructions. I dont have one so all of your feedback helps. #OmarchyMac #OmarchyLinux github.com/Kb2uka/Omarchy-M4…

Just finished my first pr using the Mac Air M4 running Omarchy. This is now my remote daily driver. #OmarchyMac #Omarchy #OmarchyLinux

Omarchy's GPU now works on the base M4 MacBook Air with the 8-core GPU. Until now the GPU driver turned the 8-core GPU away, so those Airs stopped at a text login instead of the desktop. @jefehollis found why, sent the fix and tested it on his Air. On my GPU test his Air runs at 80% of my 10-core Air, right where 8 of 10 cores should land. Already installed? Run omarchy-m4-update and restart once. New install? Grab installer update 4. The new GPU module is in its image. It hasn't been through a fresh install yet, so tell me how yours goes. USB-C monitors don't work yet, and the 15-inch Air isn't covered. DisplayLink USB adapters are next for multi-monitor: support is built and drove a virtual monitor at 60 fps, and a real-adapter test comes before it ships. github.com/Kb2uka/Omarchy-M4… #OmarchyMac #OmarchyLinux

Omarchy update for the M4 MacBook Air is out. Run omarchy-m4-update, then restart. The front USB-C port works now. It never did on Linux because its USB controller was turned off in the devicetree, so only the hinge-side port worked. I tested the same USB 3 drive in both ports and got full 5 Gb/s on each. You can now use the whole screen, notch area included. Run sudo m4-notch --show and restart, and the Omarchy bar splits around the camera. sudo m4-notch --hide undoes it. Nothing changes unless you run it. If the desktop ever fails to start, the GPU startup log is now in the system journal, so we can see why. New installer for fresh installs is out too (update 3). It fixes Airs that freeze on the boot logo, and the speaker filters now come with it instead of being built from your macOS. Nobody has done a fresh install with it yet, so let me know how yours goes. If your Air already boots, you don't need it. Want Omarchy on other M4 Macs? I'm looking for one M4 Mac mini owner and one M4 iMac owner willing to test. Reply or DM me. Thanks to @luth_v for first reporting the boot logo freeze, @ccarella for testing the fix, sheetsync on GitHub for the speaker filters, and Rish3666 on GitHub for the notch idea and the source checks. github.com/Kb2uka/Omarchy-M4… #OmarchyMac #OmarchyLinux

My daily driver right now is a 2020 27-inch iMac with an i9, running Omarchy, while I get the M4 and M4 Pro Macs up to speed. Just found out its GPU, a Radeon Pro 5300, is stuck at 300 MHz. It's rated for 1650. Running graphics-intensive software it sat at 97% busy and never went above 300. No power setting could move it. My working theory, to be confirmed tonight: the GPU's firmware starts with a 300 MHz cap that macOS raises after boot, and Linux never raises it. We wrote a small driver patch that should lift that cap to the card's own range, only on the affected iMac and Mac Pro boards. Testing it on my iMac tonight. If it works, it goes as a PR to t2linux/linux-t2-patches. That repo feeds the linux-t2 kernel Omarchy installs on T2 Intel Macs, so once it's merged a normal omarchy update brings it to everyone. #OmarchyMac #OmarchyLinux

New Omarchy update for the M4 MacBook Air. Run omarchy-m4-update and restart once. CPU idle: idle cores now power down instead of spinning. Idle power on my Air dropped from 9.65 W to 5.47 W, so it runs cooler at idle. P-core boost to 4.46 GHz, with E cores up to 2.8 GHz. A predictive heat guard keeps the chip inside the same limits macOS uses on the fanless Air: 105 °C bursts, 100 °C sustained. One busy core holds about 4 GHz for most of a 45-second job. Off switch: sudo m4-cpu-idle --boost off Headset mic on the headphone jack: plug in a 4-pole headset and its mic becomes the default input. Tested on real calls in both directions. Huge thanks to @luth_v, who built this and the headphone jack before it. github.com/Kb2uka/Omarchy-M4… #OmarchyMac #OmarchyLinux

I’ve just achieved a median clock speed of 4464mhz in the m4 air cpu via Omarchy. M1/M2 reached full clocks years ago since Apple's firmware handles thermal limits itself, and M3 support is partial with no documented heat handling…M4 is different because the firmware never throttles for heat, which is why I built a predictive guard…while AI writes the code, the beauty is in the nuisance the prompter provides. This will release later today. #OmarchyMac #OmarchyLinux #Apple

Omarchy on the M4 MacBook Air got a lot better today. Run omarchy-m4-update and you get: • GPU fix: some Airs never reached the desktop because the GPU driver expected one exact power limit. Each Air's own limit is accepted now, tested on two Airs. • The headphone jack works: clean stereo, and it switches over when you plug in. Thanks luth-v! • Closing the lid locks the screen. • No more keyring errors when you run pacman as your normal user. Thanks @rish3636! After updating, restart once for the GPU fix and headphones, and log out and back in once for the lid lock. New installs: installer update 2 works on macOS 26.6.2 (thanks again, luth-v). Same system, byte for byte. Tonight on the bench: • Working toward the 4.4 GHz bursts macOS gets, without overheating. Step one, letting idle cores sleep, is in testing: a P core at 3.6 GHz now holds a full 20 seconds and peaks at 91 °C. Without it, the same test hit 105 °C in half a second. • Working out how to prove this build runs on any M4 Mac, not just my Air, using what Asahi did for M1 and M2. github.com/Kb2uka/Omarchy-M4… #OmarchyMac #OmarchyLinux #Linux
