At first this was about getting cgminer working on mac, with minimal effort...It turns out more than minimal effort is required. Anyway It's probably a nice read if your interested in bitcoin mining.
I was using a macbook pro from Mid 2010(4 gigs of ram, intel core 2 duo)
An old linux box I built with 2 cores(amd)
And the graphics card is a 6970 or 6950 I can't remember, it's the one with the shaders off, that you can unlock with a firmware update.
And a BFL Single FPGA
So on my *nix box I was topping out at about 877
And on my mac box I'm topping out at...
However with my linux box, what i was able to do was to start using cgminer to do my graphics card which was topping out at 350 usually running at about 330 -340, and that's with --od-enable Clocks set at 920,1250, I saw the occasional problem if I bumped it to 925, 1250.
You have to have brew installed to do this
Make this script below then run it.
#!/usr/bin/perl
use strict;
use warnings;
my $brew;
my @brew_installs = qw(
autoconf automake binutils boost bzip2 curl curl curl-ca-bundle curl-ca-bundle cyrus-sasl2 db48 flex gdbm gdbm gettext glib2 gnutls gperf help2man icu jansson jpeg kerberos5 libffi libgcrypt libgpg-error libiconv libidn libpng libtasn1 lzo2 m4 miniupnpc ncurses openssl ossp-uuid p5-locale-gettext p5.12-locale-gettext perl5 perl5.12 perl5.12 pkgconfig pv qemu qrencode readline texinfo xz yasm zlib )
;
&array_cracker();
sub array_cracker(){
foreach(@brew_installs){
print $_;
$brew = `brew install $_`;
print $brew;
}
}
Now I tried hard to script the next part but I had some problems so here are some manual commands you will have to type in:
cd ~ mkdir Build cd Build git clone https://github.com/ckolivas/cgminer.git cd cgminer ./autogen.sh ./configure --enable-scrypt sudo make installI didn't have any problems after that, some people said before they did their commands they had to do this: eval `brew --config | grep HOMEBREW_PREFIX | sed 's/: /=/'` sudo bash -c 'echo '$HOMEBREW_PREFIX/share/aclocal' >> `aclocal --print-ac-dir`/dirlist' I imagine you would want to do that after all your installs from the perl brew script. So what's the verdict on speed. By using cgminer on my *nix box rather than poclbm i picked up about 10Mhs, it seems to consistently run at 362. Now the bitforce fpga, seemed to run about 800 on average, sitting in the same place with the side cover off, and as high as 1000(on the mac). However, moving it to it's new location, it seems to be running consistently in the high 800s. What does this mean....Well I can't leave it hooked up to my mac all the time as it is a laptop I use for work and have to go places with it as such. However, it's new location on a wire shelf(ie a shelf less likely to get hot), it's side panels taken off, those are permenant. And when i finally reconnect it to the linux box, I will be using cgminter to run both my fpga and gpu. And next weekends experiment will be trying the bitforce with raspberry pi, and also switching them away from deepbit.net, and back to my favorite pool fireducks horrible horrendous terrible tremendous pool. PS My mac command looked like this: cgminer --scan-serial /dev/cu.usbserial-00001024 --url deeptbit.net:8332 --user dusty@safenachos_fam --pass hammer --verbose Reason being the /dev/tty.usbetc Didn't work, and I'm sure there is a duhuh explanation for why that is, but just in case you didn't know.
