Important PSA: Do NOT update to macOS Sonoma 14.5
Update: This is now resolved. More details here [social.treehouse.systems].
We are receiving reports that video output on some or all machines is broken after this update (possibly only desktops). We don't know yet whether this is an Apple regression or a bug/issue in our code. We are still investigating and will update with further details.
Update 1: We have confirmed that Asahi's recoveryOS instance still works, so this is not another major Apple bug situation, nor is there any danger of your machine in general becoming unbootable/unrecoverable. Users should hold off on updating even if they don't plan to use Asahi for the time being, as we don't know yet how easy it will be to fix the problem once Linux becomes unbootable.
Update 2: We believe this only affects M2 series desktops (Mini/Studio).
Update 3: We have identified the root cause, but we're still tracking down some issues. This was caused by a bug/assumption in our code coupled with Apple changing memory layouts in this update. It will be fixed with an upcoming m1n1 update.
Update 4: Fix is available as a m1n1 stage 1 update. Please run the Asahi Linux installer again (curl https://alx.sh | sh) and choose the 'm' option when prompted to upgrade.
@AsahiLinux Are there any issues we can check to follow the progress on this?
@yanns @AsahiLinux they discuss in realtime on Matrix channel
@AsahiLinux
maybe I was lucky but my MBA15 M2 sonoma 14.5 upgrade did not break my #Fedora39 setup, and the upgrade to #Fedora40 was smooth.
@AsahiLinux this is the very reason I'm too scared to use Linux outside of just testing it out for fun. Critical things have a not too seldom tendency to break, sometimes catastrophically like this. Too bad, I really want Linux to succeed, but there's no way i can trust it as my main system.
@torsteinv If Linux was your main system then you probably wouldn't be doing macOS upgrades the day they come out, so you wouldn't be affected.
macOS has had worse bugs released (making some machines completely unbootable and unrecoverable without DFU)... all software has bugs.
@AsahiLinux thanks for chiming in. I trust the OS developers to have quality tested their updates before releasing them. Yes Apple has had some lemons, but anecdotally i have never experienced them, and i update always on day one and have done so since 2006. Guess im just lucky. On the few times i have tried linux since 2004 (last in 2023) - either on a dedicated PC, dualboot on mac or virtual machine, updates eventually (within a month) break the linux system. cant be a coincidence every time.
@torsteinv @AsahiLinux I definitely sense some bias on your answer… I can recall at least 4 major MacOS bugs recently… ( java not working, usb hubs not working, audio not working, cups not working ) and many more that range from allowing root access with an empty password field to corrupting your recovery image. I don’t want to make this thread go into any OS Wars discussion, only wanted to provide you with examples of what Asahi mentioned, all software has bugs. What I cannot find is any Apple community channel where they discuss over their bugs ;)
