I am new to Bitcoins, and I'd like to get started mining, but I'm on OS X. I've tried several different mining applications, and none of them have worked for me. I've got nothing but errors. Is there a mining application that has quick and easy setup?
Try the DiabloMiner app. It uses an older version of Diablo Miner that should work. The developers behind bitcoin mining software usually do not put much effort into Mac compatibility mainly because of two aspects:
Most Macs (iMac/Macbook/Macbook Pro) are not suited for mining because they have poor ventilation, which causes overheating issues.
Apple's OpenCL implementation is not very good. There are constant complaints about its inefficiency and incompatibility with mining software.
