# XID mining with MMM: Mac mainnet setup and monitoring

## At a glance

XID is xCoin’s token; MMM is the Mac Metal Miner application. Configure mainnet and a public payout address in MMM, then save that address on the XID monitor. The website reads existing records; it does not start mining on your Mac.

## Confirm which MMM you are using

MMM searches can return miners for other coins. This guide concerns [SystemThreat/MMM](https://github.com/SystemThreat/MMM), linked by xCoin, and the XID mainnet. Check the current repository documentation and release before downloading or upgrading.

## Match the address and pool to mainnet

XID mainnet payout addresses start with xpa1r; txa1r belongs to the retired testnet. A prefix alone is insufficient: copy the complete address and validate it. Use the [MMM mainnet instructions](https://macmetalminer.com/) to verify network, pool host, port and explorer rather than reusing old testnet settings.

## Check local activity before remote records

Check MMM’s engine, current worker name and share activity before looking up the address remotely. Distinct names make machines easier to recognize, but a worker name does not establish a physical device count. Pool records can lag behind local changes.

## Add the address to the web monitor

Open the [XID / MMM monitor](https://iotahome.site/en/projects/xid) and save the public address and a name. Each project supports up to 10 browser-local addresses and an export backup. Google sign-in does not synchronize this new-project list.

If workers are missing, check whether the chosen pool is covered by the source list, then inspect the fetch time. Continue with [hashrate and shares](https://iotahome.site/en/learn/xid-worker-hashrate-shares) or [balance and reward maturity](https://iotahome.site/en/learn/xid-rewards-balance-maturity).

## Common questions

### Does saving an address start mining?

No. MMM mines locally; the website only reads public records.

### Are MMM and XID separate currencies?

No. Here MMM is the xCoin miner application and XID is the token being mined.
