Move bitcoin data from Windows to Mac Is it possible to move the Blockchain data from Windows to Mac? The wallet on windows is synced, the one on mac is not. The wallet on Mac has had some bitcoins sent to one of its addresses. Would it be safe to copy the blocks and chainstate folder to the mac from windows without losing the bitcoins?
The blocks, chains, and all that excessive data can be tossed. All you need is your wallet.dat which contains your private key.

I like to think of it this way... The bitcoin network is like a massive bank full of billions, trillions, and so on of vaults. You can put coins into any vault without needing a key to that vault. You can only take coins out of a vault IF you have a key to that vault (your wallet). Your coins are never stored on your actually computer. Only the KEY to the vault is stored on your computer. That key is used to access your coins. Downloading the blockchain is simply a way of letting your bitcoin client know how many coins you have, who you sent coins to, and who sent coins to you. Its like a virtual copy of those billions of vaults, which mostly all you don't have access to. Only that vault whose key you possess. Good luck!
