1) Macbook Pro 2017. Radeon Pro 560 with 4GB of GDDR5 memory, dedicated GPU. It also has an integrated Intel GPU + graphics switching. Some additional notes that might help:
I have yet to get this Radeon Pro 560 GPU to mine with ANY software (and "unavailable" in MinerGate GUI). My guess is that the built in graphics switching messes something up. I got close with ETHminer. I can get it to list both devices / GPUs. But cannot get it to mine ETH with the Pro 560. For some crazy reason it WILL mine with the integrated version, which doesnt make sense because it doesnt have 4GB of RAM. It must be using shared memory or something. As it only mines at about 1.5 - 2 MH/s of ETH. There is an article on Steemit, How to mine ETH with GPU on your Mac by soon8013 saying he got his Radeon Pro 560 to mine ETH. But he is wrong, his setup is doing the same error/glitch as mine as is actually using the integrated GPU. he gets the same 1.5 MH/s, the Pro 560 should be getting quite a bit higher than that. I want to bounce some questions off of him and get some updated info on that blog post, if Steemit would ever approve my account! soon8013 if you read this, keep an eye on your terminal when execute ethminer, you will see even when you think you are selecting the dedicated GPU, the console tells you you are actually mining with the intel integrated, hence your low hashrate! Get in contact with me please.
MY OTHER GPU. On an HP Pavilion laptop. I believe I am having a similar issue to #1... I have an Intel integrated GPU + a dedicated NVIDIA GeForce GTX 960M 2GB GDDR5. When I run Benchmark in the GUI, Minergate crashes... And my hashrates while mining seem quite a bit low for a 2GB GDDR5.
WHY CAN WE NOT SELECT WHICH GPU TO MINE WITH IN THE GUI? This would be such an improvement. Intensity seems to not do anything, lets replace that or add a drop down list to select which GPU you want to mine with on the selected coin.
I should probably try playing with some command line miners to confirm my thoughts on #2. I am a programmer and have some other ideas about this, Minergate send me a private message or reply here to get these things worked out. This comment probably warrants its own support thread, maybe I will create another.
