In simple terms, very few users/maintainers run such old systems, so they do not get much testing. Software projects also tend to move forward and older OSes often simply cannot build them any more.</div><div><br class=""></div><div>As you can see from</div><div><br class=""></div><div><a href="https://www.macports.org" class="">https://www.macports.org</a></div><div><br class=""></div><div><span style="caret-color: rgb(33, 37, 41); color: rgb(33, 37, 41); font-family: -apple-system, BlinkMacSystemFont, "Segoe UI", Roboto, "Helvetica Neue", Arial, sans-serif, "Apple Color Emoji", "Segoe UI Emoji", "Segoe UI Symbol", "Noto Color Emoji"; font-size: 16px; background-color: rgb(255, 255, 255);" class="">"targeting mainly OS X El Capitan v10.11 and later (including macOS Mojave v10.14)</span><font color="#212529" face="-apple-system, BlinkMacSystemFont, Segoe UI, Roboto, Helvetica Neue, Arial, sans-serif, Apple Color Emoji, Segoe UI Emoji, Segoe UI Symbol, Noto Color Emoji" size="3" class=""><span style="caret-color: rgb(33, 37, 41);" class="">”</span></font></div><div><br class=""></div><div>What that means is, whilst < 10.11 is not officially un-supported, anyone running such old systems should expect to run into problems.</div><div><br class=""></div><div>As you can see from </div><div><br class=""></div><div><a href="http://packages.macports.org/rust/" class="">http://packages.macports.org/rust/</a></div><div><br class=""></div><div>rust has not built for < Darwin 14 (macOS10.10) for a number of releases.</div><div><br class=""></div><div>If you search for trac tickets for rust at</div><div><br class=""></div><div><a href="https://trac.macports.org/wiki/Tickets" class="">https://trac.macports.org/wiki/Tickets</a></div><div><br class=""></div><div>you will find a number of open tickets for this.</div><div><br class=""></div><div>Chris</div></body></html>
