I have a MacBook Pro 15" late 2016 and want to mine using an eGPU (GeForce GTX970) attached to it via an Akitio Thunder 2.
I have followed the tutorial (http://macminer.fabulouspanda.com/blog/index.php?post/2018/01/28/How-to-mine-Scrypt-Adaptive-N-on-macOS-(Garlicoin-GRLC-and-others)) and everything seemed to work. However I am getting a very low Hashrate of 1.75 KH/s. This surprises me since according to http://dracoix.io/garlic/ my GPU should produce about 250 KH/s.
I then downloaded the compiled sgminer-gm from fabulouspanda and run following command:
"./sgminer --algorithm scrypt-n --nfactor 11 -o stratum+tcp://eu.stratum.garlicpool.org:3333 -u jarikut.GeForceGTX970 -p x -I 9 -d 2"
The Hashrate increased to 11.6 KH/s which is better but still pretty far away from anything with three digits.
Also the algorithm scrypt-n seems to not exist since it switches to ckolivas instead?
[20:50:09] Algorithm scrypt-n not found, using ckolivas.

I was wondering what I was doing wrong.
If you have an idea, please let me know 🙂.
