SWarp (https://www.astromatic.net/software/swarp/) is the only stacking program I use most. It works exceedingly well.

I believe that SWarp is available for the Mac. (I have never needed to look for it before but here it is: https://ports.macports.org/port/swarp/ )

I use a local installation of astrometry.net to put the WCS on my images. Toddle over to https://astrometry.net/ for links to both the on-line plate solver (“use”) and how to drive the local installation (“download”). I already knew that a MacOS version of the local installation exists.

FWIW, I use “ANSVR” to put a WCS on images taken with Maxim DL under Windoze for the purpose of a rough and ready indication of the centre of teh field for synchronizing the mount’s idea of its pointing location to the telescope position. Never tried stacking with SWarp under that OS but often use Maxim DL’s stacker to see when enough subs have been taken to give a good enough SNR for photometry. AN and SWarp are used subsequently to do a proper job.
