In preparation for the BitcoinPrivate fork, you'll want to move your ZClassic into one of the recommended wallets prior to the snapshot. This video shows how to install the ZClassic Electrum Wallet on a Mac.
Note: At the time of the recording of this video, the Snapshot Time was not yet announced. The snapshot for both BTC and ZCL will take place at February 28 5PM UTC.
There are two ways to move private keys into the ZClassic Electrum Wallet: either by importing or sweeping. This video shows how to import and sweep private keys into your wallet as well as how to back up your wallet.
