I'm having an invalid date issue on mist. (https://github.com/ethereum/mist/issues/525)

I'd like to just try to redownload the blockchain again.

How can I do that ?

Depending on your OS, go to one of

  • Mac: ~/Library/Ethereum
  • Linux: ~/.ethereum
  • Windows: %APPDATA%/Ethereum

then delete the chaindata folder and restart Mist.

Make sure you don't delete the keystore folder


I believe this chaindata directory has been moved under another parent directory called geth:

MacOS: ~/Library/Ethereum/geth/chaindata

Additional Information: If you look under the Ethereum folder (I ran ls below), you'll see something like:

$ ls geth history keystore rinkeby testnet

If you want to force a redownload of the for the Ropsten test network for example, you can just delete: ~/Library/Ethereum/testnet/geth/chaindata on MacOS.
