    Hello,

    I need help in this issue. My Dash-Qt wallet doesn't open and says :
    "Failed to load masternode cache from mncache.dat"
    I just installed a new version 0.12.2.3 and it is still with the same problem. I'm on OS High sierra, but the problem was even on my previews OS.

    Can you help, please ?

    Adam

    Hi Adam!

    Make sure Dash is not running, then open Finder and go to ~/Library/Application Support and find your DashCore folder. In that folder, delete mncache.dat and see if Dash starts properly. If not, you can also safely delete all the other .dat files EXCEPT for wallet.dat. Restarting Dash should cause it to recreate these files based off new information retrieved from the blockchain. Let us know how it goes!

    Thank you a lot strophy !! Amazing, it worked. It didn't work by deleting mncache.dat alone so I deleted all the others EXCEPT wallet.dat as you said :)
    Now it is synchronising.

    Yaaay I have my coins back :D
