Greetings: a new EndeavourOS convert here. I can confirm that you can indeed install EndeavourOS on macbook laptops. I successfully install on a Apple MacBook “Core 2 Duo” 2.4 13" (Mid-2010) macbook. And all is working without issues as of now. Only minor issues I experienced was laptop occasionally freezing. This was due to an NVIDIA graphic driver issue. Issue can easily be solved by following the instruction on the EndeavoursOS Welcome app, under NVIDIA users and the NOUVEAU section.
The instructions are as follows.
sudo pacman -R xf86-video-nouveau
sudo nano /etc/mkinitcpio.conf
Then go to the line
MODULES=()
And change it into:
MODULES=(nouveau)
Save it with [CTRL+X]
Then type:
sudo mkinitcpio -p linux
Issue solved! Good look and enjoy a great distro.
