Answer 1

The most likely explanation is that you are already running another instance of MultiChain on the same computer, for the same blockchain. You can check for this using the top command.

I've the same error with the same conditions:
$ multichaind chain1@localhost:9701

MultiChain Core Daemon build 1.0 beta 2 protocol 10008


ERROR: Couldn't initialize permission database for blockchain chain1. Probably multichaind for this blockchain is already running. Exiting...

I've already 2 nodes running and I need 3rd for tests.
Also running it on os x

If you want to run multiple nodes on one computer, use the datadir parameter to ensure they are using separate directories for their data.
