Speaking of Xcode, I keep being offered to upgrade it, but it will only

I assume this upgrade offer is coming from the Mac App Store. I'm not
sure why it would offer you a version of Xcode that's not compatible
with your OS. It's supposed to know when something requires a newer OS,
and only display it as an "incompatible update" which cannot be
installed. That's what happens for me on Sierra.
Yep, the App Store, and no, I don't why either, but it does say
"incompatible update" now (it didn't used to).
The first time I tried that, I got a message about something being
incompatible with this box which I couldn't write down fast enough
before it reverted to Sierra. The next time I tried (paying more
attention this time), it bombed out because a critical file was
missing...
I can't really diagnose the problem based on that description. Upgrading
to High Sierra will not fix the gcc49 build failure, but if you'd like
to upgrade to High Sierra anyway and are having trouble, please let us
know your exact computer model, and the specific error messages you're
encountering.
Sanitised version attached; it's a bit out of date, but the hardware has
not changed.
I'll attempt another High Sierra upgrade later, when I have a few hours to
spare, and report back.
