Just an update to anyone who wants to use the mac wallet. It's been added to the OP and it's packaged with a shell script. The script removes the old Pesa wallet files (except for the wallet.dat). Run this script before using the wallet and you should be all set.
Hi Max,
Have you been in contact with bittrex regarding unfreezing the exchange wallet.
I would love to get my coins out of the exchange and start staking.
