As you downloaded the Ethereum blockchain from a torrent and imports the old wallet.dat file, you will probably experience problems with the balance. The -Rescan command is an effective tool in the Bitcoin-QT client that helps update your wallet data to reflect the blockchain changes. In this article, we guide you through the process of running the “-rescan” on the Mac from the console.

Prerequisites

  • Bitcoin-QT is installed and updated to the latest version.

  • The wallet imported from the old blockchain source (such as torrent).

  • Ethereum-compatible computer with MAC operating system.

  • The necessary permits to read and write files on your local machine.

Step by step instructions

  • Open the Terminal : Start the Terminal application on Mac, which can be found in applications/utilities or in the spotlight by searching for “terminal”.

  • Change the directory : Find the directory where you want to run the -Rescan command. For example:

`Bash

CD ~/Table/Ethereum-Block Chain

`

Replace ~/desktop/Ethereum-Blockchain on Mac to actually reach the Ethereum blockchain files.

4.

`Bash

./bitcoin -qt -rescan

`

Note: The prefix / indicates that this script itself must be performed from the Bitcoin-QT application itself. This is because the purpose of the “-rescan” command is to update your wallet data without asking for a user input.

What to expect

The “-rescan” command attempts to synchronize the Ethereum blockchain and update the wallet balance. You can see some outputs indicating progress, such as:

`

The Rescan thread started: 0x12345678

  • Scan block …

The 1 -scanned block 1 successfully.

The Rescan thread is ready.

`

If you do not see a single output or the process takes too long, problems may arise with your wallet or blockchain source. Try to restart Bitcoin-QT and try again.

Troubleshooting Tips

  • Make sure the Wallet.dat file is in a valid format and is not damaged.

  • If you experience problems by importing the old wallet.dat file, try to restore it to default settings or using another Wallet.dat file.

  • If the -Rescan command does not upgrade your balance, check the Blockchain source errors or invalid data.
