Well I finally got around to doing some testing on my Macbook Pro circa 2008. I built the installer image just today with
guix system disk-image --file-system-type=iso9660 \ gnu/system/install.scm joshua@dobby ~$ guix describe Generation 45 Mar 03 2020 23:16:24 (current) jmacs 54f8408 repository URL: https://notabug.org/jbranso/guix-packages.git branch: master commit: 54f84080d7459e74cd33cf434c1077c082ce6508 guix 4b759d3 repository URL: https://git.savannah.gnu.org/git/guix.git branch: master commit: 4b759d3c548270eba348521669bae15c9e5b72bc In the past, I had to run open the grub command promt and run "configfile (hd0,msdos)/boot/grub/grub.cfg". Guix's installer does now allow me to see the "EFI boot" option when I hold down the "option" key on start up. That is an improvent. I had to test the manual installation method. The graphical installer does not work on my macbook. It just flickers on and then off. Shortly after grub boots into the installer, I briefly see a blue screen, then black, then blue, then black, etc. I can switch to a virtual console and proceed with the installation that way. Perhaps, we should try to start the graphical installer only 5 times. If it fails, then just produce an error message and suggest the user switch to another virtual console and try the manual install. Manual install worked. I had a weird issue when I made the btrfs filesystems. "mkfs.btrfs -L my-root /dev/sd3" gave me an error like "failed to execute /gnu/store/eudev/santsnthsnthau32psu/lib/udev ID_BTRFS_READY=0", and it repeated on every boot. The error message on each bot looked like: udevd failed to execute /gnu/store/eudev/santsnthsnthau32psu/lib/udev ID_BTRFS_READY=0 I configured EFI boot with 1 btrfs partition. I enabled gnome, mate, xfce, and enlightenment services. The install took about an hour. In the past, I configured a minimal install with no desktop services or window manager services. I have found that trying to install a desktop service fails halfway through. However, this time, the install worked just fine. GDM started just fine. It even recognized my dvorak layout. It did not in the past. Progress. I first tested Gnome. Gnome took a long time to fully load. I had a mouse that could move around for 5+ minutes with no background image before the "Welcome to Gnome" screen popped up. I navigated through the default gnome setup easily. No issues. Gnome appeared to be working just fine. Next I tried testing Enlightenment, which started just fine. The Enlightenment welcome dialog started first. I clicked through a few screen, but it appeared to get stuck picking default mouse bindings. The dialog box said, "Enlightenment sets default mouse bindings for objects". It hanged on that screen after I clicked "Alt" for 10+ minutes. I did a hard reboot, which is what really screwed me. I should have switched to a virtual console and tried to shut off that way. Anyway, after hard rebooting, grub attempted to load my OS. The grub screen went away, and the boot process showed a cursor, but no text. I waited for 5 minutes before hard rebooting. I got the same issue. So my Macbook Pro currently has no OS on it. :( But my ThinkPad T400 works just fine! Thanks, Joshua P.S. If anyone has any suggestions of where I can look for errors, please let me know. I would be happy to try installing again.
