What dropping support means is that we no longer fix bugs that only occur on unsupported releases, and we no longer run our tests on old releases. That includes both running the Go tools, and running programs produced by the Go tools. We don't go out of our way to cause Go to break on unsupported releases. That said, there are occasionally cases where we change Go to require APIs that are only available on newer releases. That has happened on macOS in the sense that we no longer support 386 or arm at all; we only support amd64 and arm64. I don't know offhand if there have been other such cases for macOS (there have been for Linux: for example, we now require the accept4 system call to be supported (except on arm)). Our position is that it is actually Apple that is driving the upgrade cycle you mention, not us. Apple chose to drop support for High Sierra back in 2020, so anybody running a High Sierra system connected to the Internet is at risk. Should we invest our limited resources on supporting releases that even Apple has declined to support? If Apple continued to support High Sierra, so would we.
