Fedora Asahi Remix 40 is now available

We have announced the release of Fedora Asahi Remix 40!

You can install Fedora Asahi Remix by following our installation guide. Existing systems, running Fedora Asahi Remix 39 or 38, can be updated following the usual Fedora upgrade process.


The default enabled HDMI audio support is unfortunately unstable. It can break audio on the system completely, hang applications trying to use audio and break restart and shutdown.
We will update the kernel and install images as soon as possible (within 24 hours) with disabled HDMI audio.

In the meantime HDMI audio can be disabled by adding apple_dcp.noaudio to the kernel command line:

sudo  grubby --update-kernel=ALL --args="apple_dcp.noaudio"

Additional known bugs:

  • generating the initramfs can take several minutes. The last printed line is "dracut[I]: *** Including module: drm ***‘’’
  • HDMI displays are possibly be only refreshed at half of their refresh rate
  • Bluetooth LE on WiFi 6E devices (bcm4388) is broken in kernel-16k-6.8.9-402.asahi
  • after initial installation or upgrade to f40 the speaker volume is at 100% (and KDE plays a sound at login)
  • depending on the fractional scale factor KDE Plasma might show single pixel lines/rows of background
  • after changing the fractional scale factor systray panels might not show correctly (fixed by logging out and back in)
  • picture breaks after changing the Color Profile in KDE Display settings, fixed by a complete redraw (change virtual desktop, Press Power than esc)
  • with active Color Profile and Blur desktop effect taskbar, logout/shutdown dialog and panels might show as solid black which stays even after closing the panel. (Virtual desktop switch fixes it, workaround either unset Color Profiile or disable the Blur effect)

We have published a new kernel (6.8.9-402.asahi) that disables HDMI audio by default to mitigate the issue. On existing systems, dnf update should take care of installing it and resolving the issue. We’re also building new install images to include it by default and will update the release images in the installer as soon as these become available.

Updated release images that include the new kernel disabling HDMI audio by default and few other minor bugfixes are now live. For existing Fedora Asahi Remix 40 systems a dnf update will be enough.


The system upgrade to Fedora 40 should be offered in Discover after fedora-asahi-remix-appstream-metadata is updated to 20240511-2.

edit: Removed Gnome Software as that apparently doesn’t work

If there are still active Fedora 38 based installs (end of life in ~10 days) the same applies for system upgrades to Fedora 39.

kernel-16k-6.8.9-403.asahi is available now and fixes the Bluetooth LE connection issue, the half-rate rendering with external displays and improves frame pacing in kwin_wayland (less stuttering).

To update run sudo dnf --refresh offline-upgrade download and sudo dnf offline-upgrade reboot or use Discover / Gnome Software.
