There is, actually, a Mac version of XEphem but it’s slightly hidden!  At the download site, there are three disk 'images' (they’re CD-ROM sized compressed tar files).  Disks #2 and #3 are star catalogs, but #1:

        contains a ready-to-run Mac XEphem.  I’m going light on details here because more detailed procedures might belong elsewhere, but (a) XEphem requires the Motif GUI library (embedded in the app) and X-11 (sort of included with macOS), and (b) since the author hasn’t digitally signed the app, it needs to launched via a right-click. XEphem has a slightly 'olden' look, but it’s an impressive work.  It’s author has stopped working on it but, aside from discovering more moons of Jupiter, this field changes only slowly!  Comets, asteroids, and artificial earth satellites are all kept up to date from the usual sources.
