No idea of course whether somebody will fix it. It's just that young people tend to have fairly old Macbooks (i.e. >= 10 years) since younger models in that universe are often outside of their budget. > I wouldn't object to a configure check if anybody wanted to write > a patch to add one. Like I said, I don't care much, but if you want I can send a small configure script patch of course. That's not a big deal. So roughly you want a warning for pre-10.14 and error out on pre-10.12, right? G3, if you want to take care about sending this patch instead, very much appreciated of course. :) > > > "Last two versions only" is our support policy for OSX for a reason, > > > and the reason is that there just aren't very many people running > > > OSX and actively working on QEMU.

Sure, I just wanted to bring that to your attention. In fact security support policy by Apple is somewhat unpredictable. There is no official statement which branches are covered by security fixes. They simply decide on a case-to- case basis whether or not to release updates for certain old release branches. Best regards, Christian Schoenebeck
