Description

The "ocl_cuckaroo" plugin crashes immediately on my Mac Pro 2012 (Mojave), with 2 CPU's (12 cores total), and an AMD Radeon RX 580 (8GB). Here is the section of "grin-miner.toml" with applicable configurations: plugin_name = "ocl_cuckaroo" [mining.miner_plugin_config.parameters] platform = 0 device = 1

Screen print of the crash is as follows: ocl_cuckaroo_plugin_crash

What is interesting is that I am able to run the "ocl_cuckatoo" plugin just fine, as well as the "cuckaroo_cpu_compat_29", works OK. Screen prints are as follows:

ocl_cuckatoo_plugin_works

cuckaroo_cpu_compat_29_plugin_works
