Update: installed mint. Seems work. Had a problem where it couldn’t see the HD. Had to change an option in grub
Pasting what I found online to fix it:
“”" thank you so much! what was the solution!
for anyone might read this in the future: in the bootmenu where u can select which version of linux u wanna boot u can press “e” and then u need to add intel_iommu=off at the end of the line of the “linux” row - i had some double dashes at the end for me it did the job when I add them before the double dashes.
Then I could see the harddrive and install mint mate on my old macbook air
also needed later on to set the parameter permantent by opening a terminal and used this command sudo nano /etc/default/grub
edited this line like this: GRUB_CMDLINE_LINUX_DEFAULT=“quiet splash intel_iommu=off” then save and exit nano and this command for updating the boot thingy
sudo update-grub “”"
Even when it gets it right, you have to then check it carefully. It feels like a net loss of speed most of the time. Reading and checking someone else’s code is harder than writing your own
