[GAP Forum] XGap on OSX Mojave

[Russ Woodroofe]

Dear Bryan,
Gap.app is xgap compatible, and installs just about everything you need to GAP.  It includes only GAP 4.10.0, but you can also use it with your own copy of GAP, if you prefer.

https://cocoagap.sourceforge.io/

I haven't tried itc with it, and would be interested in your experiences.  (If you have trouble, email me directly and I'll try and help.)
Best,

 --Russ
