Just to preface, I am somewhat new to Ethereum, and I'm trying to learn my way around.

So I recently downloaded the Ethereum Wallet from the Ethereum website, and I subsequently uninstalled it once I realized that it was downloading the entire blockchain, which I just don't have space for on my machine (on a mac).

However, I noticed that I am missing about 9 gigs of space on my machine even after deleting the app and the data. Any idea why I'm missing space? Any files I should delete?


On OS/X, Ethereum Wallet places the blockchain data in the chaindata subdirectory under $HOME/Library/Ethereum/geth.

You can remove the chaindata subdirectory.

If you want to save any private/public keys, copy $HOME/Library/Ethereum/keystore and it's contents to a backup location.

If you have no use for Ethereum Wallet on your computer, you can remove the data from your computer (after saving your keystore if necessary) by deleting $HOME/Library/Ethereum and it's contents.

  • Thanks for your response. It's very odd, but I did all those things and I'm still missing like 9 gigs of space. Really bizarre. Thank you though. – w23 Mar 14 '17 at 3:38
  • Have you emptied your Trash folder? – The Officious BokkyPooBah Mar 14 '17 at 3:39

    Start terminal. Go to $HOME/Library . Type du -hs * to find the large directory. Go into the large directories and use the same commands to find where the large files are. If you cannot still find where the space went, start at '/' . – The Officious BokkyPooBah Mar 14 '17 at 5:50

    A little late to the game, but after deleting large files from mac, I learned that if one uses time machine, its local cache can be cleared to recover space. e.g. "sudo tmutil disablelocal" watch your disk space drop, then switch it back on "sudo tmutil enablelocal" – user16555 Aug 2 '17 at 22:42

You'll also want to get rid of the application support folder. This will take care it of all: rm -rf ~/Library/Ethereum && rm -rf ~/Library/Application\ Support/Ethereum\ Wallet
