Hey there. I've got an iMac 27' mid 2011 which has a dying hard drive inside, which is causing it not to boot. The only other Mac I have around is a PowerMac G5. I've read in the Apple Support forum that you need a system running El Capitan or later to use createinstallmedia, but I don't really have another choice, except on windows (which I haven't read anything on about this).

What I want to do is create a bootable USB drive with any recent enough OS for the iMac (I believe it can run anything from Mountain Lion to High Sierra, it was previously running High Sierra).

Any suggestions on my options are appreciated. Thanks!
