Replay Mod Forums

Hey guys!
I was trying to use the Replay Mod and was not expecting these many complications attempting to install.
Problem:
When I try to render, after bringing up the GUI, it goes to the minecraft loading screen and freezes. (This screen)

Environment:
Mac OS X El Capitan
Replay Mod Beta 1.12.2
No retextures or packs active
Only other mod is Optifine

If you need a video showing the problem, say so and I will make one.
Thanks,
All the best,
Grify

glad to see 2 years later that the mods are still hard at work!
