MacBook Pro - A1278


  • Will not run Qubes OS 4.1
  • Will not even boot the 4.0.4 installer ISO
  • 4.0.3 works like a charm from a usability perspective (not so sure about security-wise)
  • sys-net must be run in paravirtualized mode (PV), and required kmod-wl to be installed, as well as a systemd service (attached below)
  • The following HVMs work great: Windows 10, Windows 11, FreeBSD, Android x86, most major Linux distros. Oh, and TempleOS works too!
  • If you close the lid, it will sleep, and when you open the lid, it will wake, however the screen will just stay black (illuminated, though). I will write further updates on this as I investigate.

More details will follow…

Thank you @alzer89 for this HCL report, which is now online.

Darn it! I got unreasonably excited, seeing this.
