Greetings and salutations.

Under my current circumstances, my only system is my hard modded classic xbox and an 8 year old macbook pro running El Capitain. Essentially, I'm trying to find a way to create an ISO once I've decompressed the files and end up with the folder so I can burn it. I only have a stock 8GB HDD in it so going the FTP route is kind of out of the question. I've been all over google trying to find software for a mac to make an xiso file and the only thing I came up with was a command line program (which I haven't used command line since I was like 6 and had windows 3.1 and qbasic) and the only commands I can find are just for extracting ISOs though the program boasts xiso creation capabilities.

Any suggestions or even a point in the right direction (outside of the usual "GET A PC" "USE BOOT CAMP" because my computer literally overheats and shuts off after about half an hour of use and then I have to put it in the fridge for about half an hour so trying to do an OS install would be a total disaster) would be appreciated more than you can know!

Cheers!
