What Happened?

I'm currently trying to implement OTB into my mulitplayer server, so was testing my new modpack in singleplayer. In starting new worlds, the Overworld and End biomes generate perfectly fine with no hassle, but the Nether comes up with this:

I did look at this guide from y'all, but I am on a Macbook unfortunately, so I can't use NBTExplorer.

Not sure if you could use the logs (it didn't crash or anything, nether biomes just... don't work.) But if you do need them I can provide.

For the record, there are no other biome-related mods in this pack- they are all related to Origins, crafting recipes, or UI.

Is there some additional information I could provide for a response? I really want to help my friends to explore this interesting mod, but if I don't get a response soon I'm probably just going to go back to BetterX.
Regardless, I'd like to say I enjoy this mod a lot and am a proud patron!

the instructions are listed perfectly there?

Thank you for the response!
The terrablender link (middle one) doesn't work when I click it, and also seemed like it wasn't what I'm looking for- I do want the nether to be replaced, by the BYG biomes. If I misunderstood and turning that off would allow the BYG biomes, though, then my bad! I'll try it tonight.
As for the existing world fix, I am on an Apple product. NBT appears to be windows only, otherwise I would have tried that. ^-^'

send your level.dat

VICTORY!
