I recently installed Linux Mint on a 2008 MacBook 4,1. It mostly works well but the shutdown process sometimes gets stuck right at the end. I have searched around for a solution and have so far increased the default shutdown limit from 10s to 100s and also blacklisted the USB2 drivers (USB ports still work fine using the USB3 drivers). The problem happens about half the time. I dual boot with Mac OS X 10.7.5 and use ReFind as a boot manager although I can also boot from Grub. From neofetch:
OS: Linux Mint 20.2 x86_64 Host: MacBook4,1 1.0 Kernel: 5.4.0-81-generic Packages: 2371 (dpkg), 5 (flatpak) Shell: bash 5.0.17 Resolution: 1280x800 DE: Xfce WM: Xfwm4 WM Theme: Mint-Y Theme: Mint-Y [GTK2/3] Icons: Mint-Y [GTK2/3] Terminal: xfce4-terminal Terminal Font: Monospace 12 CPU: Intel Core 2 Duo T8300 (2) @ 2.4 GHz GPU: Intel Mobile GM965/GL960 Memory: 1431MiB / 3916MiB
I took a photo of the screen after it froze which might show what I need to do to fix it. I hope I posted in the right section. Thanks in advance for any tips.
If not a fix for this particular problem, are there any configuration changes that would force the MacBook to shut down once the "
Reached target power off" is posted. The second picture shows a kernel panic left as the last message before it froze.
