1  Other / Beginners & Help / Major noob guide needed to get private key from wallet.dat using pywallet (Mac) on: January 06, 2018, 09:34:23 PM
I have an old wallet.dat that's either too old or corrupted to simply drop into bitcoin core and make work. It has been suggested that I try using pywallet to extract the keys so I can upload them to a new wallet, but I have no coding experience and have not ever used python before.   Ultimately, I need to get a nice idiots guide on what I need installed and what I need to type to extract the keys using OSX. Help appreciated. Thanks.

So far I have made it this far, but not sure where to go from here...
Mac OS X:
 1. Install MacPorts from
 2. sudo port install python27 py27-twisted py27-pip py-bsddb python_select
 3. sudo port select --set python python27
 4. sudo easy_install ecdsa

2  Bitcoin / Bitcoin Technical Support / Possible to back up wallet.dat file by dragging and not backing up manually? on: December 05, 2017, 03:35:45 AM
Hi everyone.

A few years ago I gave my brother BTC for XMAS. He hasnt touched it since and was using Bitcoin QT at the time. We are looking to transfer the funds to a hardware wallet, but when getting him to upload his wallet.dat file, we ran into a snag. It seems he didn't do an actual back up of the wallet app, and instead, had a time machine back up of the computers hard drive made, and when he gained access, we grabbed the wallet.dat file from his bitcoin folder. When loading it into the app on my computer, the funds are coming up as 0. I checked the address on and the funds are still there.

Any suggestions? Can you make a usable backup via dragging and dropping the .dat file as opposed to backing it up manually?
