  How do you mean it's stuck? the log there looks as though it's working, what's happening with hash rate and accepts?

  Well, it seems to be starting and then stopping constantly... The log screen fills, flashes and seems to start over.

  
  

  The log from my MBP is quite different. It is running at 1.9 to 2.1 Gh consistently. Not showing any starting and restarting, just a nice constant flow of information.

  
  

  At the moment this one on the iMac shows .62 Gh. I've seen it vary from .19 Gh to about .72 GH.

  
  

  Is this line from the log the problem?

  I also see this every time before it clears the screen and seems to start over.

  I just have no clue why there is such a vast difference on the two machines and I'm surprised especially because the MBP is quite old and ruining OS X 10.7 while the iMac is brand new and running OS X 10.9.

  
  

  I installed the same drivers and both computers are running the newest version of MacMiner.

  
  

  Again, any help would be greatly appreciated!

  Ah, I think this is an issue with the USB port, are you using one of the ones on the back of the iMac? Do you have a powered USB hub? It would be worth trying another port

  The powered USB hub just arrived today and right now I have it attached to the MBP since it's running so well. Another hub will arrive tomorrow so I'll try it on the iMac. I've tried the Antminer on the ports on the keyboard and currently it is plugged into a port in back.

  
  

  Thanks so much for your quick responses. If I still have trouble I'll be back!

  
  

  Here's to a great weekend for all!

  The ports on the keyboard I wouldn't have expected to work at all but I'd hope that back would work OK - let me know how you get on! Have a good weekend

  Hello again...

  
  

  Well I received my second powered USB hub and plugged it into the iMac at the back and I'm essentially getting the same problem readings as before:

  Any suggestions? A driver problem/conflict? How would I check that to troubleshoot?

  Are the pools the same, and how about the network connections?

  
  

  There's something bad going on

  you installed the silabs driver I'm sure? You could try deleting that

  
  

  /System/Library/Extensions/SiLabsUSBDriver64.kext

  
  

  and installing it again

  
  

  also try switching around with each port on the back of the iMac

  Well, it been a terribly busy week that included surgery for hubby and flu for me.... eeeeek!

  
  

  So, the Antminers have been running so smoothly and effortlessly on my MacBookPro that I have not messed with them.  You know, the old if it ain't broke don't fix it...

  
  

  Anyway, I have have a couple of the new Gridseeds on the way. Will I be able to use them with MacMiner... I hope hope hope so! Thanks for your incredible support. As soon as those Antminers collect enough goodies I'll be sending some your way!
