Wow very detailed escalation report!, please hang in there. Very nice video work btw!
This may be due to how I had you install Berkely. Did the trouble begin after you downloaded our snapshot? Is it happening now if you close and re-open PandaBank? It might be a good idea to close PandaBank and brew uninstall berkeley-db4 and then brew install berkeley-db@4. I had a typo the first time I asked you to install it. I second guessed myself and diverged from our recommended version, the berkeley-db@4 is what we are using on ours.
Thanks jommy,
I followed your recommendation and didn't have any different result. I do a little web development, but I wish I were familiar with XCode, swift, qt, etc; I'd dive right in and help.
