This App will only work on GPUs that are Compute Capability 5.0 or higher.
See list of supported GPUs here, https://en.wikipedia.org/wiki/CUDA#GPUs_supported

This App is for Sierra 12.4 and above, using a CUDA 9.0 or above driver.

Best Driver; Sierra zi3v CUDA 9.0.222 http://www.nvidia.com/object/macosx-cuda-9.0.222-driver.html
The Only settings needed for the CUDA App is the -unroll N setting in the app_info.xml cmdline section if you have less than 3 GB of vRam. Unroll Autotune and -bs is built-in for zi3v.
If you wish to use 100% CPU per task, use the cmdline setting -nobs for zi3v.
<cmdline>-nobs</cmdline>

Restrictions for vRam, Do Not Exceed the numbers below for GPUs with;
1 GB vRam use -unroll 2 or Less
2 GB vRam use -unroll 6 or Less, you may use -unroll 8 depending on your monitor setup,
<cmdline>-nobs -unroll 2</cmdline>

If you have 3 GB or more vRam, you can use the Autotune settings which will set the number to equal the GPU multiProcs, Autotune is preset in zi3v.
<cmdline></cmdline>

Run One task at a time unless you have over 4 GB of vRam, even then One task will probably be best.

Finish your existing GPU tasks, then place the expanded files in the /Library/Application Support/BOINC Data/projects/setiathome.berkeley.edu folder.
If you are not familiar with changing owners with the Terminal, just reinstall BOINC to set the correct owners/permissions.
