I installed elementary OS Juno on an old iMac 5,1. The Computer uses a 32bit EFI, which is not able to boot elementary OS Juno so I decided to follow Matt Gadients guide for a little workaround. You can find the workaround here: https://mattgadient.com/2016/07/11/linux-dvd-images-and-how-to-for-32-bit-efi-macs-late-2006-models/
I am wondering if this modified distro is still safe to use?
Matt Gadient describes how to modify the isos with a little C program to make them bootable on an 32bit EFI Mac. I did not download the isos from that site, instead I just downloaded the c program from Matt's site, which you can find as a text here: https://dedicated.mattgadient.com/linux-mac-iso/isomacprog.c.txt
I compiled the c programm with
cc -g -Wall isomacprog.c -o isomacprog
and modified the offical elementary OS Juno distro with it by doing something like
Bytw: the modified iso has the same MD5 checksum like the iso modified by Matt himself, so he definitley hasn't done anything else with the distros.
I burned the iso to a DVD and installed it on the iMac. It is running just fine. Yet I haven't connected the computer to the internet since I am not sure if it is still safe to use.
I don't know anything about c programing so I'd like to ask if this little c program does anything more than just making the distro bootable? Is it still safe to use this distro or contains it some kind of virus?
