For the past 3.5 yrs I’ve been using Unison to sync files between 3 macs. It works great. In fact, since I installed and set up my profiles for syncing, I’ve not needed to change a thing. Until yesterday. I upgraded to El Capitan on each of the 3 macs. I went to run Unison to sync the days work and – an error. -bash: unison: command not found Oh dear. I looked in the search path and couldn’t find Unison.
