Hi guys, I'm Nyak. I've been thinking up a mod, but can't find any decent software that's compatible with my computer (MacBook Air) and need some mod assistance. Anything you guys can find to point me in the right direction for making mobs, item drops, blocks, biomes, etc. Thanks!

This mod so far includes:

Ore Golems (See my other post): Golems in underground dungeons that explode in a shower of their themed ore.

Ents: Giant tree monsters that rise out of the ground whenn you walk on their grass-covered backs

Giants: Same general idea as Ent, except that they rise out of mountain biomes.

Other ideas are appreciated!
