cgminer contains unofficial Mac binaries of cgminer, a command-line bitcoin mining tool.
cgminer is a combined FPGA, and ASIC bitcoin and litecoin miner written in C, cross-platform for Windows, Linux, and OS X, with stratum support, remote interface capabilities, support for multiple simultaneous mining devices, and advanced caching and detection algorithms that maximize cryptocoin mining efficiency.
There's a workaround in this version to minimise the risk of the man-in-the-middle attack of redirecting you to a different pool you don't want to be hashing on. Stratum reconnect will only honour the request if the reconnect is to a server with the same domain name.
Fix for some overflow errors on stats with massive hashrates/shares.
Fix a major memory leak which mostly affected hashfast users.
Fix for a failed connection after a redirection that would then never return.
Devices with unique serial numbers of 4 or more characters will now be displayed by their serial number in the status bar.
