This is a developer preview of the Tails operating system for Apple Silicon (arm64) Macs. Please understand that this is what it is: again, a developer preview. No security guarantees can be placed on the OS, first and foremost because the Tails Team was not involved at any stage in this port. The code for building the image is hosted at [1] in the wip/asahi (development) branch and in the 7.x/asahi (release) branches. The latter are rebased continuously on Tails' stable branch. Since Tails' Debian archive snapshots do not contain arm64 packages, and since the code that manages selecting these snapshots is quite involved [2], instead of writing a patch to point the image builder back to the official Debian archive, to build the images I'm hijacking my DNS resolver. In more detail, I point the domain names [3] and [4] to a webserver running nginx with the configuration at [5], which redirects some URLs back to Tails, others back to Debian, and others still back to Tor Project's Debian archive. Additionally, Debian's kernel does not support Apple Silicon Macs yet, as a large part of the required bits is not upstream yet. For this reason, the Tails images for Apple Silicon Macs come with the Bananas kernel -- i.e. the Debian kernel + asahi patches maintained by the Debian Bananas team [6] -- installed. Finally, the Tor Project has not started building releases of the Tor Browser for linux arm64, despite official nightlies being available since December 2024 [7]. For this reason, the Tails images for Apple Silicon come with unofficial builds of the Tor Browser [8] installed. If you find bugs and are willing to report them, feel free to do so at [1]. For a history of the port to arm64 see [8].
