Davoud:
[XEphem] requires an
X-Windows environment such as Apple's X-11, which is standard with
OS 10.7 and below. Beginning with 10.8 one must download and install

Paul Schlyter:
So Xephem runs natively on older versions of Mac-OS, butik the
current Mac-OS needs some extras to run Xephem....

Not exactly. All UNIX versions that I know of require an X-Windows
environment to run GUI software such as XEphem. The Mac OS never came
with such software installed. It used to be on one of the install
disks, and it was an optional install. Now it's on the Internet and is
an optional install. A distinction, one might argue, but one without a
difference: prior to OS 10.8 one needed an X-Windows utility to run
XEphem in the Mac's BSD UNIX environment. Beginning with OS 10.8 one
needs an X-Windows utility to run XEphem in the Mac's BSD UNIX
environment.

Further, it has nothing to do with running "natively." XEphem never ran
on BSD UNIX or any other UNIX without an X-Windows environment
installed.
