In fact there are a number of more recent posts / threads that address this. For example, see the link michheld posted (immediately above).  For me, the built-in update  has worked for a while.  Menu Bar > Help > Check for Updates I see that some of my old posts are in this thread.  Since they have been superseded, I will edit have edited them so that others don't think that what was true in 2020 is still valid.
