<p dir="auto">Should we drop support for OS X 10.6 Snow Leopard in Go 1.5? In Go 1.6?<br>
It's 5 years old and not supported by Apple anymore.<br>
It was the last OS X to support 32-bit machines, which is why we've kept it this long.<br>
But there are problems with cmd/cgo on these old systems that we're just never going to fix (for example <a class="issue-link js-issue-link" data-error-text="Failed to load title" data-id="51287539" data-permission-text="Title is private" data-url="https://github.com/golang/go/issues/8009" data-hovercard-type="issue" data-hovercard-url="/golang/go/issues/8009/hovercard" href="https://github.com/golang/go/issues/8009">#8009</a> and <a class="issue-link js-issue-link" data-error-text="Failed to load title" data-id="58622500" data-permission-text="Title is private" data-url="https://github.com/golang/go/issues/9967" data-hovercard-type="issue" data-hovercard-url="/golang/go/issues/9967/hovercard" href="https://github.com/golang/go/issues/9967">#9967</a>).</p>
<p dir="auto">We should still keep darwin/386 until Apple stops running 32-bit binaries on 64-bit systems, since it's useful to be able to run 386 all.bash on OS X machines.</p>
<p dir="auto">As discussed in <a class="issue-link js-issue-link" data-error-text="Failed to load title" data-id="53296882" data-permission-text="Title is private" data-url="https://github.com/golang/go/issues/9495" data-hovercard-type="issue" data-hovercard-url="/golang/go/issues/9495/hovercard" href="https://github.com/golang/go/issues/9495">#9495</a>, it might be time to end our support for OS X 10.6.</p>
<p dir="auto">I'm trying to find Apple's policy on supporting older versions of OS X, but it appears they haven't published anything publicly. (Which seems outrageous to me, but whatever.)</p>
<p dir="auto">The major concern, I believe, is that OS X 10.6 is the newest version of OS X that runs on pre-EFI macs (or something?). I think <a class="user-mention notranslate" data-hovercard-type="user" data-hovercard-url="/users/robpike/hovercard" data-octo-click="hovercard-link-click" data-octo-dimensions="link_type:self" href="https://github.com/robpike">@robpike</a> actually has one of these old machines.</p>
