Hi I saw your Post as i am trying to retrieve my misssing character how would i run this code on a mac book pro?
It's a Python script... a MacBook Pro should have python install by default. You just need to copy/paste the 'script' from that post into a text file, edit the 'corrupted_wif' value to be the WIF of yours that is missing one character and then save the file as "corrupt_wif.py" or some other name... as long as it ends in .py
You will also need to make sure you have the python bitcoinlib library installed. So open a 'terminal' and type:
pip install bitcoinlib
Once that is installed, you then change the current directory in the terminal to where you created the .py file... and use:
python corrupt_wif.py
That should run the script for you.
This very short video shows how to create the script using the text editor and run it:
