+07:54 < VinDuv> So I’ve been looking at how macOS installation from USB works on M1 Macs and I think it might be interesting for the Asashi installer. The way it works is that there’s a hidden plist file on the USB drive that references a macOS
+                application on the drive; if this file is present, the USB drive will show up in the power-button-held boot menu, and when selected, it will run the application. It doesn’t seem to care about file signature
+07:54 < VinDuv> (it works even if the app is just a shell script) and it looks like it’s in 1TR mode.
+07:56 < VinDuv> So the installation workflow from 1TR could be “plug in a USB stick, hold the power button, select Install Asahi” instead of having to manually open the terminal and run curl | sh. The installer doesn’t even need to be graphical since
+                it’s possible for the launched shell script to start the recovery environment’s Terminal and giving it an arbitrary command to run.
+07:59 < VinDuv> This is also not limited to external USB drives; it also works if the files are in an APFS volume in internal storage, which I guess might be useful to have a Asahi Recovery boot option in the boot menu or something.

+19:14 <VinDuv> marcan: I have done a bit more testing with the .IAPhysicalMedia file and it looks like ProductBuildVersion can be any value including blank. ProductVersion seems to be checked against the minimal macOS version supported by the Mac; on my mini the icon shows up in the boot menu only if it’s >= 11.3.
+19:15 <VinDuv> Maybe it should be set to a higher value for forward compatibility with future Macs that will require 13.0? I’ve tested setting it to 99 and it works.
