MacMiner
MacMiner is a graphical cryptocurrency-mining application for macOS created by John O'Mara under the name FabulousPanda. Its Objective-C interface was designed to configure, start and monitor command-line mining backends.[1]
Design and backends
MacMiner historically bundled binaries for BFGMiner, CGMiner and pooler's cpuminer. The application's source repository says the source code of those miners and of the BFGMiner API helper belongs to their respective upstream projects rather than to MacMiner itself.[1] The repository also contains binaries or directories for several later altcoin-mining backends, but their presence does not establish current support on modern systems.
The project manual describes separate windows for CPU, GPU and FPGA/ASIC mining. BFGMiner was the default GPU window and exposed options such as intensity, work size and Scrypt mode. The CPU window used a cpuminer backend for supported altcoins, while the FPGA/ASIC window was intended for supported external devices and could report temperature data when the hardware exposed it.[2]
These are historical capabilities of the bundled versions. They should not be read as a claim that CPU or GPU mining is economical, that every named algorithm or device still works, or that the bundled miners are current.
Interface and monitoring
The documented workflow was to add one or more pools, open the desired mining windows from the View menu, configure each backend, and start it. Each window had backend-specific settings. The API Output window could display more detailed device statistics and monitor compatible BFGMiner or CGMiner instances on the network.[2] This monitoring interface uses the mining backends' APIs; it is unrelated to Bitcoin Core's RPC interface.
Because mining can keep processors or graphics hardware under sustained load, the project manual advised users to monitor temperature and cooling.[2]
Development status and compatibility
The repository describes support beginning with Mac OS X 10.6 and says the Objective-C project can be built in Xcode after adjusting code-signing settings when necessary. The maintainer describes development as less active than in the past and invites community forks and small contributions.[1] The available documentation does not establish compatibility with current macOS releases or Apple Silicon, so modern-system support is unverified.
Licensing
The MacMiner repository permits attributed, non-commercial redistribution and public modification under project-specific conditions. Those terms differ from a standard unrestricted open-source licence. BFGMiner and CGMiner retain their upstream GPLv3 licences, and other bundled components may have their own terms.[1]
