I have a (Wall Mounted Display) Mac Mini that I hoped to sling a GridSeed Unit off and Scrypt Mine

Gary Hewett

Sadly the unit is NOT upgradeable software wise -- I'm stuck at 10.6 on that unit. 

  Model Name: Mac mini

  Model Identifier: Macmini1,1

  Processor Name: Intel Core Duo

  Processor Speed: 1.66 GHz

  Number Of Processors: 1

  Total Number Of Cores: 2

  L2 Cache: 2 MB

  Memory: 2 GB

  Bus Speed: 667 MHz

  Boot ROM Version: MM11.0055.B08

  SMC Version (system): 1.3f4

I have not had much luck finding let along running anything that either

• Works
• Recognizes the GridSeed Unit

I do not need a GUI - more than happy to work in terminal but this unit does NOT have XCode and it can no longer be gotten, HomeBrew and git won't install properly as a result so I'm pretty much stuck with pre-compiled binaries. Seems like by the time I find one old enough to run on the machine it's too old to have any knowledge of GridSeed. 

Any options or suggestions? 

I really don't like the thought of having just bought a $200 paperweight...

Update -- I have the GridSeed device working on my "big" mac so I know what is required to have a working unit at this point.

The "trick" seems to be to get the grid seed enabled version of MacMiner, copy it over to /Applications, drill do via the command line to: 

• /Applications/MacMiner-GridSeed.app/Contents/Resources/gridseedcpu4/bin

Note - I renamed by "app" so I could tell it apart form the "normal" version. 

The magical incantation that finally worked (for me -- your mileage will of course vary) was:

• ./minerd  -o stratum+tcp://multi.ghash.io:3333 -u techmag.7 --freq=850 -G /dev/cu.usbmodem5d11

According to GHASH.io I'm running about 325(isn) khs 

Yahoo! -- I'll be a CryptoBillionaire in no time flat!

Now - I figured I could just move this over to the MacMini and get this noisy contraption off my desk and yet on that box the problem appears to be: 

Gary-Hewetts-Mac-mini:bin garyhewett$ ./minerd  -o stratum+tcp://multi.ghash.io:3333 -u techmag.8 --freq=850 -G /dev/cu.usbmodem5d11

-bash: ./minerd: Bad CPU type in executable

Sigh  

Macs are supposed to be easy -- right? 

Anyone got a clue as to what is next?

I think I need a 32-bit compiled version of minerd but one that is of course compiled to handle gridseed. Any suggestions on how/where that might be found?

I'll have to compile a new 32bit version and just hope it works with 10.6! I'll update you here

Have you tried booting the 64bit EFI? Apple locks Snow Leopard into 32bit mode for device compatability on some hardware but 64bit app code should work just fine.
