Hi, yes I replaced the new blank wallet.dat file with the backup one

Quote

I reinstalled OS X via USB and reinstalled Bitcoin Core. Replaced the wallet.dat file with the one I had backed up.

Quite lost at this point

Thanks

Go to File > Receiving Addresses. Do any of those addresses look familiar? If not, then the wallet may not be your wallet.

Next we can also try to dump the private key to see if the wallet has it. Find an old address that you used before. Go to Help > Debug Window and click on the Console tab. Type into the box at the bottom

Code:

dumpprivkey

where

is the old address.

If the address is in the wallet, then you should see black text appear in the console window that starts with a '5', 'K', or 'L'. That is the private key for that address, DO NOT SHARE IT WITH ANYONE. If you do see it, then that means that the wallet is yours. If you see red text with an error, then the wallet may not be yours. Try doing that for a few addresses to make sure. If for each address you do get the private key, then try rescanning again. If you do not, make sure that you properly copied the wallet file and that Bitcoin Core is actually reading that wallet file.
