Razer Blackwidow Chroma not supported by synapse 2.0?

Hello, so i am a mac user, and i recently bought razer blackwidow chroma. I wanted to try the RGB lighting with modes, so i intstalled synapse 2.0 because it's the only one compatible with my mac. When i downloaded it it said it couldn't find any razer devises. I tried pluging and unpluging my keyboard, but it still doesn't work! Please help as soon as possible! Thank you in advance !
