The web site doesn't appear to mention what OS versions it can *build* on. It 
just mentions what OS versions it's "for". Previous versions would have run on 
earlier OS versions, but required a newer SDK to compile, and judging by the 
fact that TeXShop4 only built on our High Sierra builder, I guess that's still 
the same. I have been working on adding ports for older SDKs, so maybe then we 
can fix this situation.

Right. Or you could combine everything into a single TeXShop port, and offer 
different TeXShop versions to different OS versions as needed.
