    MAC / Cold Storage Guide
    (Mac 10.10.3)


    We have our Dash Wallet installed, encrypted and working.
    As of
    'Mac Wallet Setup Guide'
    https://darkcointalk.org/threads/mac-wallet-download-installation-guide.3850/

    To secure our funds I suggest “cold storage” (moving the wallet.dat file off the computer onto several USB Sticks)

    1. Starting Point
    [​IMG]

    2.
    - Quit Wallet (always!! before you do anything inside the Dash Folder!!)
    - Create New Desktop Folder (I use dates in the Naming)
    - Move Wallet.dat file into new folder

    3.
    Encrypt (Backup Folder again /as double paranoid)

    - Start “System Utility” App (located in Applications –Utilities)
    [​IMG]

    4.
    Disk Utility Open
    - File – New – Disk Image from Folder
    [​IMG]

    5.
    Select Folder (Cold Storage Folder we created earlier with the wallet.dat file)
    [​IMG]

    6.
    Chose Setting
    - Image Format: read/write
    - Encryption: 245-bit
    [​IMG]

    7.
    Chose Password
    - Password: The longer the better (do NOT loose it!!)
    - DESELECT: “remember password in keychain”
    (As if this is selected, anybody using this file on your computer will have a very easy task to decrypt, as the password will be saved in the keychain, so DESELECT!!)
    - A new Folder .dmg will be automatically created on your Desktop

    8.
    Move to "cold"
    - (1.) DRK .dmg Folder off Computer onto several USB Sticks
    - These USB Sticks Should be stored in Several Locations
    (I am using 5 USB Sticks, 3 in my House, 1 in a Waterproofed box, 1 Outside my house)
    - After several Backups (of DRK.dmg) erase (2.) original Folder as not needed and uncrypted
    [​IMG]

    And Done.
    “Cold Storage” means that your wallet.dat file (which holds your coins) will be off the computer
    And
    Off the Internet connection.


    Remember:
    This is my personal (Double Paranoid way), you can do this easier without an extra level of encryption, but safety first !

    9. Suggestion:
    I am using KeePass for all my Passwords:
    http://keepass.info
    (This is an Open Source Software, created by Dominic Reichel, I am in touch with him personal due to freynder MN KeePass integration)
    - With KeePass you can create Long (terrible complicated Passwords, save them in the App, and copy /paste into any app needed)
    - In case your keystrokes will be recorded (Malware) the attacker will only see a copy/paste command
    - Use Keepass database on several devices
