Hi Guys,
I'm having the same problem (an unconfirmed transaction since 7 days) but cannot even open bitcoin-qt with the terminal on mac
"The file /Users/Charles 1/Bitcoin-Qt.app does not exist"
So how could I run the zapwallettxes ?
I did open /Applications/bitcoin-qt.app --args zapwallettxes which opens Bitcoin Core but nothing changes
First of all, do not hijack someone else's thread. You have your own issue, make your own thread next time.
Secondly, you don't have to use zapwallettxes anymore. Instead, open up bitcoin core and go to Help > Debug Window and click on the console tab. Then in the box at the bottom, type
abandontransaction
Where is the transaction ID of the transaction you want to double spend.
