@MJG017 as far as i know, the ARM iso file seems to be the correct version for when you're using a mac to try and download ubuntu through the UTM.
When I said I've already downloaded the Ubuntu iso 64 arm iso file, I meant as in that I've already downloaded that file from the Ubuntu website before I started using the UTM to try and install Ubuntu through there.
Either way, nothing still seems to be working for me on my end. Since I have the class tomorrow afternoon, I'm gonna be using one of the lab PCs in that class along with plugging my SSD on there, since the teacher said that the hypervisor is already installed in the lab PCs 😄
I really appreciate for all your help!! ❤️
