I have installed Hunspell for my language, Icelandic, into InDesign CC 2017 on various macs using various systems. Used the same way I have used since ID CS6 up to 2015.
It all works well, except on macs using the Sierra (10.12.2) system.
Has anyone had similar situation with their Hunspell installs? Has anyone found they needed to do something differently while installing?
