I am having problems getting Mist to sync, so would like to run geth --fast. I can not find the folder to run geth from? Do I need to install it separately, I thought it was bundled with Mist? I am new to terminal so some basic instructions would be appreciated. Any help would be appreciated. I am running OS X 10.11.4 and Ethereum-Wallet-macosx-0-7-2.
Install geth - Mac
Install homebrew by pasting this line and hitting enter :
/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
Install geth by running each of these in terminal one at a time (copy, paste, hit enter, wait)
brew tap ethereum/ethereum
brew install ethereum
Run geth fast
- Open Terminal and type
geth --fastand hit enter
If you have already started syncing Mist you may want to delete your chaindata. I would recommend doing this as it ensures you get the full benefits of --fast, and allows you to start fresh. For those re-syncing after months, it'll help eliminate corrupted chain files, ensure no problems from before homestead - > after homestead, and help get rid of bloat.
Open Mist and go Accounts - > backup - > accounts.
If you have any accounts, copy the files inside keystore (they look like
UTC-2016-5-16.......) to your Desktop AND a USB drive (or two). These are your encrypted private keys. If you lose these, any ETH inside these accounts will be inaccessible and lost forever.
Go up a folder level and find the chaindata folder. Delete just this chaindata folder. Alternatively, you could move it to your Desktop if you think the sync might not work and you want to recover it later.
geth --fast has been deprecated. Use
geth syncmode="light" insted.
