Having a tough time getting Linux mint installed
I was gifted a 2015 27 inch iMac. I'm trying to install Linux mint on it. I formatted my USB to use FAT and GUID. Then burned the cinnamon iso to it with balena etcher. I get to the boot drive selection screen, choose the efi, and then nothing. I just get a black screen. I'm not sure what I'm doing wrong here.
I should note that I am a noob when it comes to Linux and to Mac.
Any suggestions?
