Problem getting bitcoins into Bitcoin Core on Mac I'm using Bitcoin Core on a MacBook Pro. A few month ago my computer crashed and I lost everything, so when I got a new computer I reinstalled Bitcoin Core but now I'm having an issue getting my bitcoins to show up in the newly installed Bitcoin Core. I have both the BTC address and the transaction ID under which the bitcoin were transferred to me when I purchased them and I have tried to add both of these on the page where you request payment, without any luck. Not sure what to do to get my bitcoin back as Bitcoin Core has even finished its synchronisation with the network and they are still not showing up...

You would need a backup of the old wallet.dat from bitcoind, the bitcoin address and transaction information are available to the public. If you were able to recover funds with that information then anyone would be able to 'recover' your coins. Unless you have made a backup you have most likely lost your coins. In the future make sure you always have a backup of your wallet.dat or private keys/seed words (depending on wallet).
