why does the wallet keep going in and out of sync??
1.7 on Mavericks OSX
I'm not a Mac user, but from what I understand you have to find the Mintcoin folder and delete everything in it EXCEPT THE WALLET.DAT FILE...make a copy of the wallet.dat just in case. Then do a complete new instal of the new wallet 1.7 or 1.8.
By doing the complete new instal, you will be downloading the entire blockchain again nad this should fix all the problems.
