i am still not sure how to do this. if i download this version i have to apps called Ethereum-Wallet.
i need a forked version because i have eth.
is it possible to just rename the wallet i need for etc to Ethereum-Wallet-c.app?
i am using OS X.
You can rename "Ethereum-Wallet-c.app" to just "geth" if you wish, that is what I did.
Read the github on the link,
"Geth 1.4.10 build that is exclusively for the Ethereum Classic network. This node has all the DAO code removed from the client and requires no additional flags to use the Ethereum classic network." by whatisgravity
I would not recommend putting this "geth" wallet on the same machine that has been running the forked version unless you know what you are doing. It will pick up your eth keystore and use your eth address. This is where you can get replays if you do this.
Also you will have the wrong blocks in the roaming folder. You need to start from fresh on a new machine or remove all your eth files from your machine and do the "geth account new" command in geth to get a new address and new "keystore".
Remember to keep your keystore backed up. It contains info to recreate you wallet on any machine
Your old "Mist" will work fine as a GUI to access your new "geth" node address
Why not use a light wallet for one chain and a full node wallet for the other chain?
