Comment (by thetrial):

 Again KPxc gets broken by (other) updates, It is the update of quazip,
 affected is {{{libquazip}}}, the {{{libquazip*.dylib}}} files get
 deleted/replaced. KPxc doesn’t start. One can bring back the missing files
 via Time Machine, but this being linked issue is VERY bad. This seems to
 be a problem one couldn’t even stop with fixing a version. A very
 interesting aspect that KPxc has no older builds for older OS. Kind of
 ignarrogance, indeed. And yes, I know, El Capitan is sooo old. But I’m not
 going to throw away working machines.
