 confirm that go 1.7 may include fixes for Sierra that are not in 1.6.3:

 I think you're right. While I didn't find any mention of a problem in the
 [https://golang.org/doc/go1.7 Go 1.7 release notes] nor the
 [https://github.com/golang/go/issues?q=milestone%3AGo1.7.1 1.7.1
 milestone], further searching turned up:
  * [https://github.com/golang/go/issues/16352#issuecomment-236918099
 GH#16352] 2016-08-02: "As of Sierra Beta 4, this issue is again relevant."
 (Go 1.6.3 was released before that,
 [https://golang.org/doc/devel/release.html#go1.6 2016-07-07].)
  * [https://github.com/golang/go/issues/16570#issuecomment-236979733
 GH#16570] 2016-08-02: "Wanted to add this also happens with 1.6.3"

 tordevSZ0, mcs, I made a build of meek-client and meek-client-torbrowser
 using Go 1.7.1. Please try copying it into your installation and see if it
 helps:
   attachment:meek-0.22-18371-3-go1.7.1.zip
   attachment:meek-0.22-18371-3-go1.7.1.zip.asc
 If you prefer to build it from source yourself:
 {{{
 git clone https://git.torproject.org/pluggable-transports/meek.git
 cd meek
 git checkout 0.22-18371-3
 (GOOS=darwin GOARCH=amd64 cd meek-client && go build)
 (GOOS=darwin GOARCH=amd64 cd meek-client-torbrowser && go build)
 }}}
