Mining rate for Macbook Pro

hanstheredhansthered Member Posts: 3
Hey guys,
I've been CPU mining with my machine (just a macbook pro) for a week. So far 0 ether.

I decided to sign up there just to make sure I was actually doing work on the network.

I do indeed see myself there under the auspices of "Pl7/yryIzIHYhm+Ouy4=" my super-secret client name.

Now it's been another 24 hours and still no ether.

I know they say CPU mining is not profitable, but is it even possible? I would think 8 days of mining I should have something.

I mean 1 ether is like $0.14 right now isn't it? I'm pretty sure I've used that much electricity.

Please advise,

    Sounds like you need to do a bit more homework. :)

    A CPU is going to mine somewhere in the KH/s -- not MH/s.

    Find any of the online mining calculators and plug your numbers into get an estimate of how long it will take you to mine different amounts of Eth. With a CPU it will likely take many weeks.

    And no, Eth is not currently $0.14 -- try more like 4x that at $0.57

    See here:

    Here is an online mining calculator:

    MrYukonC, thanks for the information! I am actually farming at 4mhz according to under "Pl7/yryIzIHYhm+Ouy4=". It looks like I should be able to farm up 1.7 ether per week.

    I guess I need to double check my power settings and make sure I'm not going into stasis at night etc and just wait it out.

    Thanks again, more research is needed for sure.

    I just looked at your stats on the stats page and it does indicate that you're mining somewhere between 3.3 - 4.1 MH/s (BTW, that's megahash / second -- not mhz :) )

    Anyway, if you scan across the entire row of stats for your node, you can tell there are other problems. Everything in red pretty much means there is a problem.

    Your node is not up to date with the latest block count. You will not get credit for anything you mine with an out of date block chain.

    Yeah, I saw that this morning and restarted my client, then everything went green. I am trying to get the GPU mining working at the moment so I have gone offline temporarily.

    When I install Eth following the guide on the install seems to succeed, but attempting to start the mining process with:

    eth --frontier -b -i

    fails with:
    dyld: Library not loaded: /usr/local/lib/libminiupnpc.13.dylib
      Referenced from: /usr/local/bin/eth
      Reason: image not found
    Trace/BPT trap: 5
    I thought I might have better luck with the Ethereum Guide but when I got to the last line of the On MacOSx section where you run:

    brew reinstall cpp-ethereum --with-gpu-mining --devel --headless --build-from-source

    I was met with:
    CMake Error: Error required internal CMake variable not set, cmake may be not be built correctly.
    Missing variable is:
    CMake Error: Could not find cmake module file: /tmp/cpp-ethereum20151025-41057-1j8nqy1/CMakeFiles/3.3.2/CMakeCXXCompiler.cmake
    CMake Error at CMakeLists.txt:17 (project):
      No CMAKE_CXX_COMPILER could be found.
      Tell CMake where to find the compiler by setting the CMake cache entry
      CMAKE_CXX_COMPILER to the full path to the compiler, or to the compiler
      name if it is in the PATH.
    CMake Error: CMAKE_CXX_COMPILER not set, after EnableLanguage
    -- Configuring incomplete, errors occurred!
    See also "/tmp/cpp-ethereum20151025-41057-1j8nqy1/CMakeFiles/CMakeOutput.log".
    If reporting this issue please do so at (not Homebrew/homebrew):
    Which only gave generic responses about CMake on a Google search.

    If you have any more insight it would be appreciated. Thanks again for your time BTW I know you probably have better things to do.

    Sorry, I've got no help I can offer on that one, as I'm mining on Linux.

    Did you manage to fix the "No CMAKE_CXX_COMPILER could be found." issue?

    I am running into the same thing trying to setup GPU mining on OSX Yosemite.
