Surely Macs don't support text mode (?), so that is surer to fail than sc, where text mode is the default and this is hard to change. I'm surprised that any Mac works under FreeBSD. Google knows very little about this, especially since ~2013 when Macs started getting more specialized hardware. I inherited a early 2009 iMac with broken graphics hardware that can sometimes be fixed by overheating it to reflow its solder. This system is difficult to boot even as a Mac when the solder has gaps or you are not a Mac export, and I got nowhere trying to boot FreeBSD, Linux or Windows on it (I only tried even older boot media and nothing got further than hanging with no useful error message). I'm evn more suprised thhan reflowing solder sometimes gives working hardware instead of a short circuit. Bruce
