I am trying to install Arch Linux on my MacBook. I've Etcher to write
archlinux-2021-04.01-x86_64.iso to a USB stick and as far as I can tell that succeeds. When I go into the startup manager by pressing
Alt, I select the USB stick, but then all that happens is the screen goes black and does not change. I then have to power down the laptop and power it up again.
However, I've also tried
ubuntu-20.04.2.0-desktop-amd64.iso using the same technique and that does boot successfully.
I've also tried some alternative arch installers which do not work:
What else can I try?
