MacMiner GPU / sgminer wont run - iMac Radeon 580

frequencydipfrequencydip
in Support

Thank you for any help in pointing me in the right direction. I have been unable to get MacMiner GPU or sgminer command line to work.

Computer: iMac Radeon 580 8GB
Command: ./sgminer -k lbry -o stratum+tcp://lbry.suprnova.cc:6256 -u name.worker -p x -d all -D -L errors.txt

I get the warnings:
WARNING: GPU_MAX_ALLOC_PERCENT is not specified!
WARNING: GPU_USE_SYNC_OBJECTS is not specified!
Where do I specify these settings?

Error before program crash:
Using /Applications/MacMiner.app/Contents/Resources/sgminer/bin/lbry.cl
CompilerOptions: -I "." -I "./kernel" -I "." -D WORKSIZE=256 -I "/Applications/MacMiner.app/Contents/Resources/sgminer/bin"

    Unfortunately the nicehash sgminer wasn't built with macOS in mind so it had to be patched up even to work to the extent it does - but it really needs someone to take a look at wolf-sha512.cl and get it working for Mac. You can see the pull requests for Mac support made so far and get the source here:
    https://github.com/nicehash/sgminer/pulls

    Hopefully someone with more experience can make a quick fix of it! If not I'll probably eventually get around to looking at it in more depth.

    In the meantime, I'd suggest mining a different algorithm if you want to GPU mine. It's been tested successfully with decred and keccak.

    Oh but you could try running this before sgminer at the command line to solve the first two warnings

    export GPU_MAX_ALLOC_PERCENT=100
    export GPU_USE_SYNC_OBJECTS=1
