Problems in start mining. Tried with slushpool port and with Suprnova without Sucess

Hello. I've downloaded Zcash in my Mac. I've unziped and opened the Application. I've configurated the Zcash adress as the worker of the pool, put a password and the Server:port of the pool. WIth slushpool I didn't have success and with suprnova I couln't too. It says for both: resolve: Host not found (authoritative). And it doesn't start and stays 0 H/s and 0 Sol/s. Could you help me?

The Zcash client in zcash4mac does not support connecting to a pool. You will need to find a 3rd party application for that : https://www.zcashcommunity.com/mining/zcash-mining-software/
