I've used Galerie for over 10 years now to generate photo albums for my golf site (search for the Bausch Collection if you are curious). I'm having to upgrade the OS on my desktop Mac and wasn't sure Galerie would still function. Well, on my MacBook Pro running 10.14.6 (Mojave) and the last version of iPhoto available (9.6.1), it sure seems to run just fine! Note: you can download the last version of iPhoto (9.6.1) for free from archive dot org.
