Transfer blockchain from PC to Mac I have a bitcoin wallet on my PC  but I just recently downloaded the MAC version of it.  I would like to initialize it with the blockchain from my PC so that I don't have to download it all over again.  Is that possible?

Copy over your %APPDATA%\Bitcoin directory to ~/Library/Application Support/Bitcoin/

Your AppData directory should be:

C:\Documents and Settings\YourUserName\Application data\Bitcoin (XP)

C:\Users\YourUserName\Appdata\Roaming\Bitcoin (Vista and 7)


If not, you can always run explorer %APPDATA%\Bitcoin in Command Prompt (Super-R, type cmd, hit "Run") to find it.
