The OS X 10.10 machine will be updated to OS X 10.11 and the macOS 10.12 machine will be updated to macOS 10.13.
The machines were updated to 10.11 and 10.13 respectively. X2Go Client builds (release and nightly) were triggered manually.
Symlinks have been updated to point to the correct location.
The wiki now lists links to the 10.9, 10.11 and 10.13 builds.
From now on, new release and nightly builds will only be automatically built for 10.11 and 10.13.
The 10.10 and 10.12 builds are obsolete, will not be updated any longer and the symlinks will be removed on the next release.
I will also provide 10.9 builds manually, but likely delayed.
