I crunch for Ukraine

We don't have an amd64 macOS app; I'm compiling it right now.

If you aren't using this Mac for another task, install Linux on it; this way, you can also perform OpenCL calculations using the iGPU. Plus, Linux handles bandwidth management better on older Macs. If you can install Ubuntu 24 or openSUSE, you'll likely be able to contribute more effectively.

i use it for other projects - mainly WCG :)

I crunch for Ukraine

Confirmed and fixed -- this project genuinely had zero app_versions for x86_64-apple-darwin across every app. Every Mac build so far only ever targeted Apple Silicon.

Now live for Intel Macs, CPU builds for Potamos, Keraunos, and Sphinx, cross-compiled and verified via real execution (through Rosetta) on real hardware, not just "it compiled."

Also went further and brought up OpenCL for Intel Macs with real GPUs (AMD/Intel integrated or discrete) -- Apple's OpenCL framework is deprecated but still present and functional. Along the way found and fixed a real portability bug: Apple's OpenCL compiler rejects a parameter syntax (`constant ulong b[4]`) that's valid per spec and works on every other GPU/ICD this project targets -- fixed to the equivalent pointer form, verified with a real kernel compiling and running correctly on GPU hardware.

Your next task download should pick up a real x86_64 build automatically -- let me know if it doesn't.

thanks - i see this computer got "Potamos (sequential keyspace scan) v0.05 x86_64-apple-darwin" about 20 minutes ago!
