I'm trying to deploy a contract to the Ropsten testnet using Truffle. Already tested on testrpc, worked smoothly. I keep getting the error "Exceeds block gas limit" when I try to deploy to testnet. Even when I am not specifying any gas amounts anywhere, I always get the same error.
I noticed the following warning in the geth client, which might be affecting my network, since it seems like I'm unable to mine blocks and get ether like before.
WARN [07-27|12:26:21] System clock seems off by 20.321575601s, which can prevent network connectivity WARN [07-27|12:26:21] Please enable network time synchronisation in system settings.
I'm running macOS 10.12.5 and followed the instructions here a while ago, but it clearly didn't resolve my issue. Other people who get time synchronization errors seem to be on Windows. How do I fix this on a mac?
