H’m, weird. Google suggests that pickle support can vary with Python versions, and it’s something that I have not really been aware of, until now. It’s not what the user got, and I don’t remember seeing it, when I tried to help this old friend. And that was probably at a time when I was still using 3.4, or maybe 4.x.
I don’t know the version that this user had, on his iMac, but forgot to mention the thread:
TS plans to extract the files from the iMac again, so I hope that I can report later this weekend, or nexy week.
And just for the sake of testing or preparation: Would you mind sharing some BSDDB files, Intel, or both platforms, with me? It can be through email, or iCloud, and I will pass my address in a minuite or so.
