Please remember to upgrade the wallet to Version 1.5.

Mining pools, please upgrade your wallet.

Guys, is there a mac client that works?

ATM you could use 1.4. We will try to make 1.5 available before the switch.

Graincoin OS X Wallet Binaries

I finally got around to putting together OS X wallet binaries for graincoin. Two are available:

OS X 10.7: https://drive.google.com/file/d/0B8rWObF4xz1YeERVc3cxeGJVLUE/edit?usp=sharing
OS X 10.9: https://drive.google.com/file/d/0B8rWObF4xz1Ya3c0bTlBel9hZkk/edit?usp=sharing

These binaries required changing the code in some places, so I'll put up a pull request soon at github.
