So do I. But I cannot call those I see "modern". > Was talking about x86 mainly because the initial thread, the user said > he was a newbie.

Irrelevant. That new fancy ARM Mac is using UEFI too, or so they say.

Or, for instance, NetBSD? OK, M8 is costly. Let's consider something cheaper and older, like T4 or T5. I know one can get those on eBay, heck, someone still sells T2000s, T1s, and even parts for E25Ks there. Does it still run Solaris for a certain reason? Because those that I see in my line of work definitely do. It's possible, of course, to run something other than Solaris on both T and M series (unsure about E series), I still have that LDOM running kernel 4.1.12 just because I can, but it never grew up to anything bigger than proof-of-concept.
