For Pool Mining:
XMrig is currently your only option, and you can find the binaries here (look for darwin): Release v6.10.0 · xmrig/xmrig · GitHub
For Solo Mining:
You can leverage the latest binaries here (look for darwin): https://github.com/deroproject/derosuite/releases/latest
Within you will find dero-miner which can be leveraged.
You can also use xmrig (look for darwin) (Release v6.10.0 · xmrig/xmrig · GitHub) with the --daemon parameter defined (or daemon=true within config.json).
You can find information related to how to pool mine on different pool mining pages, they usually have a getting started page. Here’s a decent list of dero mining pools: Dero (DERO) AstroBWT | Mining Pools
Solo mining is just the process of running the miner pointing at a daemon endpoint, usually ran locally. The daemon is the derod daemon binary, linked above within the derosuite project.
