i got a few support requests from DMD mac wallet users
for now the mac wallet 2.1.0.1 have bug included that let it crash if u enter transaction tab
short after releasing the next wallet that fix the actual 2.1 issues there will be also a new mac wallet
if u still want to sync meanwhile with the max 2.1.01 u have to take care u are on correct chain
compare blocknumber with
https://chainz.cryptoid.info/dmd/in case u not on correct chain (not sync at same blocknumber) u need to follow guide on FAQ thread
https://bitcointalksearch.org/topic/diamond-dmd-faq-1478653some people did report their wallet is missing coins
for them too first make sure u are on correct chain
then execute in console checkwallet and in case errors visible repairwallet
also sometimes its helping to startwallet with a -rescan option
then the local wallet.dat sync his transactions with the local copy of blockchan
to be clear ur real wallet balance is always visible on explorer
and no local wallet issues make u lose coins
as long as u have a wallet.dat contain ur private keys u will always be able get access to ur coins again
a cryptocoin wallet is not like a real cash wallet that it contains coins and banknotes
a cryptocoin wallet is more like a ebanking tool that allow u to see and interact with ur balance
and the info about the truth who own how many coins is not in a wallet its in the blockchain
the blockchain have every transaction that ever happened and was accepted by network stored inside
and the result is the true balance of any address
ur local wallet.dat is where keys are stored that give u the right access and interact with balances on addresses
and the wallet exe u start is more like a browser that let u look into the blockchain and interact with balances where u have they keys in wallet.dat
so the essence in the end what is it that u need to always be able gain access to ur balance is the private keys of ur addresses
there are two paths one is to have a backup of ur wallet.dat because they keys are inside
second is a bit more complicated but most secure to really dump and store the private keys of ur important addresses
with such keys even a damaged wallet.dat is no issue u can import the keys in new wallet.dat and have again access to ur coins
if u want to learn more ablout this topic u can find a lot info about bitcoin and explainations about wallets.dat and private keys and how to dump and import them
dmd wallet is in that area behaving the same as bitcoin and guides should work for dmd too
