Both Aquamacs 3.5 and 3.6 don't work for me on a freshly installed upgrade
to MacOS X 10.11.6 El Capitan but 3.4 does. They both crash during startup
after failing to find a dynamic library reference to "_clock_gettime",
which is apparently only available on MacOS X 10.12 and beyond. Some older,
now cheaper, hardware doesn't support MacOS X beyond 10.11 but we don't
need to feed Apple's immediate greed or to work around System Integrity
A potential fix is to build future versions of Aquamacs with a version of
Xcode 7.3.1 or earlier, which is available through
https://xcodereleases.com/. Although versions after 7.3.1 may run on MacOS
X 10.11 El Capitan, they reference software development kit SDK10.12, which
refers to "_clock_gettime". The SDK version may be checked with the
with late enough versions of Xcode. The Terminal application xcode-select
may change the Xcode version in effect for compilation if more than one
Xcode is installed. If Xcode is installed, I would suggest not installing
the Xcode command line tools, which might download a later SDK version, but
this may be overly cautious.
