      After the 755 you need a space :)

      Also type once “ls” to see what files are there, since it cant find it when you type it in caps. the ysstem cares how you write files. You can have m.sh and M.sh in the same folder and it being two different files.

          dyld: Library not loaded: /opt/local/lib/libidn.11.dylib

          Any suggestions?

          Thanks

            Are you still on a Mac or are you trying to get this working on a Mac? The thread title says mac!?

                Ok, looks like you need that library. On my mac that comes from the MacPorts package. You need to install the Macports Package: https://distfiles.macports.org/MacPorts/MacPorts-2.1.3-10.8-MountainLion.pkg

                After you have done that, you need to get root (“su -” or “sudo -i”). If you type that command you might need to type in your user account password. After you have done that, please type

                “port selfupdate”, afterwards run
                “port upgrade outdated”.

                This will have installed the ports system on your Mac. Now you need to install the missing library:

                “port install libidn”

                This will then install the libidn libraries. That is installed on my mac and it works.

                While we’re at it… from checking the required libraries, you also need to install the following:

                “port install zlib”
                “port install curl”
                “port install openssl”

                That should make it work.

                Regards,
                Andreas

                  Ok - Finally got it to work :) Thanks for all the support.
                  My next issue is the my hash rate is bad. I should be getting faster rates with the 7950 card correct?
                  Also how do I change the thread count?

                  [2013-05-14 06:07:51] thread 6: 201756 hashes, 3.41 khash/s
                  [2013-05-14 06:07:51] thread 0: 204984 hashes, 3.41 khash/s
                  [2013-05-14 06:07:52] thread 2: 169380 hashes, 3.38 khash/s
                  [2013-05-14 06:08:14] thread 3: 77220 hashes, 3.41 khash/s
                  [2013-05-14 06:08:14] accepted: 2/2 (100.00%), 27.26 khash/s (yay!!!)

                  Thanks again for all the help

                    Youre only mining using your CPU cores, not the GPU.

                    You will need to use something like cgminer to use the GPU, minerd cannot do that.

                    I’m not sure how to set this up on a Mac though.

                    Edit: Looks ok for a Quad-Core though, my i7 laptop Quadcore with hyperthreading gets similar numbers on 8 threads, (2 per core with hyperthreading).

                      This was helpful. Yes a way to get the GPU into action with the mac will be good. Power is no consideration. Just want to speed matters up.

                        You could try downloading the cgminer binary for Mac here:
                        https://bitcointalk.org/index.php?topic=166877.0
                        and give it a try with the standard parameters.

                        BEWARE: the official FAQ says:

                        Q: Can I mine with cgminer on a MAC?
                        A: cgminer will compile on OSX, but the performance of GPU mining is
                        compromised due to the opencl implementation on OSX, there is no temperature
                        or fanspeed monitoring, and the cooling design of most MACs, despite having
                        powerful GPUs, will usually not cope with constant usage leading to a high
                        risk of thermal damage. It is highly recommended not to mine on a MAC unless
                        it is to a USB device.
