The Asahi Linux project is urging users to avoid installing the first beta of macOS 27, codenamed "Golden Gate," after discovering that the release breaks the ability to boot into Linux on Apple Silicon machines. According to a report by Phoronix published this week, the macOS 27 beta makes the Asahi Linux partition invisible to the system's boot process, leaving affected users unable to access their Linux installation.
Asahi Linux is the leading open-source effort to bring full Linux support to Apple Silicon Macs. The project enables users to run Linux natively on M-series chips by building an alternative boot environment on top of Apple's proprietary hardware and firmware.
Why Betas Are Especially Dangerous
While compatibility disruptions from macOS updates are not unprecedented for the Asahi project, beta releases pose a uniquely elevated risk. Apple provides no stability guarantees in pre-release software, and changes to low-level boot and firmware behaviour can ship without warning or documentation. This means the Asahi team typically has little to no advance notice of what has changed beneath the surface.
The fundamental challenge is that Asahi Linux depends heavily on reverse-engineering Apple's undocumented firmware interfaces. Because Apple does not publish specifications for its boot architecture on Apple Silicon, the Asahi team must painstakingly analyse each firmware version to understand how the system works. When Apple alters these internals — as it routinely does during major macOS development cycles — the project can be left scrambling to identify and adapt to the changes.
A beta release amplifies this dynamic. Not only are firmware changes more frequent and less predictable in pre-release builds, but subsequent beta iterations may further alter the affected interfaces before the final release ships. Users who install the macOS 27 beta may therefore find themselves stuck without access to their Linux partition for an extended period, with no straightforward rollback path depending on the nature of the firmware changes involved.
A Recurring Pattern
The incident highlights a structural vulnerability that open-source projects face when they depend on reverse-engineering to support proprietary hardware. Each major macOS release carries the potential to disrupt Asahi Linux functionality, and the project's developers must continually invest significant effort to maintain compatibility — effort that goes toward recreating knowledge Apple chooses not to share publicly.
For the broader open-source community, this serves as a reminder of the trade-offs involved in running Linux on hardware whose manufacturer does not actively support third-party operating systems. While the Asahi project has made remarkable progress in delivering a usable Linux experience on Apple Silicon, the relationship with Apple's firmware remains inherently fragile.
Advice for Users
Asahi Linux maintainers are advising all users to hold off on installing the macOS 27 beta on any machine where they depend on Linux access. Those who have already installed the beta and lost access to their Asahi partition are encouraged to follow the project's communication channels for updates on recovery options and eventual compatibility fixes.
It remains unclear whether the issue stems from an intentional change or an incidental side effect of other firmware modifications in the Golden Gate beta. Apple has not publicly commented on the matter.
Asahi Linux 項目正在敦促用戶避免安裝 macOS 27 的首個測試版（代號「Golden Gate」），因為發現該版本會破壞在 Apple Silicon 機器上啟動進入 Linux 的能力。根據 Phoronix 本週發布的一份報告，macOS 27 Beta 使 Asahi Linux 分區對系統的啟動程序不可見，導致受影響的用戶無法存取其 Linux 安裝。
Asahi Linux 是領先的開源計劃，旨在為 Apple Silicon Mac 帶來完整的 Linux 支援。該項目通過在 Apple 專有硬件和韌體之上構建替代啟動環境，使用戶能夠在 M 系列晶片上原生運行 Linux。
為何測試版風險尤其高
雖然 macOS 更新對 Asahi 項目而言導致相容性中斷並非前所未有，但測試版帶來的風險特別高。Apple 對預發布軟件不提供穩定性保證，底層啟動和韌體行為的變更可能在沒有預警或文檔的情況下就已發佈。這意味著 Asahi 團隊通常對表層下發生的變更幾乎沒有提前通知。
根本挑戰在於，Asahi Linux 高度依賴對 Apple 未記錄的韌體介面進行逆向工程。由於 Apple 並未公開其在 Apple Silicon 上的啟動架構規範，Asahi 團隊必須費力地分析每個韌體版本以理解系統運作方式。當 Apple 修改這些內部結構時——這在重大 macOS 開發週期中是例行做法——該項目可能不得不緊急識別並適應這些變更。
測試版發佈放大了這種情況。在預發布版本中，韌體變更不僅更頻繁且更難預測，而且隨後的測試版迭代可能在最終版本發佈前進一步修改受影響的介面。因此，安裝了 macOS 27 測試版的用戶可能會發現自己長時間無法存取 Linux 分區，具體取決於所涉及的韌體變更的性質，且沒有簡單的回退途徑。
反覆出現的模式
此事件凸顯了開源項目在依賴逆向工程以支援專有硬件時所面臨的結構性弱點。每個主要的 macOS 版本都有潛力干擾 Asahi Linux 的功能，項目的開發者必須持續投入大量精力來維持相容性——這些精力都用於重新創造 Apple 選擇不公開分享的知識。
對於更廣泛的開源社區來說，這提醒了在硬件製造商不積極支援第三方作業系統的硬件上運行 Linux 所涉及的權衡。儘管 Asahi 項目在為 Apple Silicon 提供可用的 Linux 體驗方面取得了顯著進展，但與 Apple 韌體的關係本質上仍然脆弱。
給用戶的建議
Asahi Linux 維護者建議所有用戶，暫緩在任何依賴 Linux 存取的機器上安裝 macOS 27 測試版。對於那些已安裝測試版並喪失 Asahi 分區存取權的用戶，建議關注該項目的溝通渠道，以獲取恢復選項及最終相容性修復的更新。
目前尚不清楚此問題是源於 Golden Gate 測試版中其他韌體修改的刻意變更還是附帶副作用。Apple 對此尚未公開評論。
