Hi,

I have only tested the app on my system (Ubuntu 22.04) for now. This seems to be an issue with multiprocessing and sqlite, I will try to borrow a m1 macbook to try it out and see if I can reproduce your error.

Did you edit the code in background.py ? The line numbers don't seem to match with the current state of the main branch. If so, could you show what you edited ?

Thanks for trying out Memento :)

I'm also seeing this on a 2019 macbook running sonoma w/ intel silicon, python 3.11

@apirrone at a high-level, what do you expect to need to be done to convert this to run properly on a Mac? I may take a stab at it.

Hi @BradyAB

I suspect it is really just an issue with dependencies versions. I don't have an easy access to a Mac, so if you manage to make it work, please make a PR and I will merge it !

Thanks !

Hi,
I'm facing the same issue on 2019 Intel Mac.
Any ideas on how to fix or debug this.?

@aldrinjenson @venturaEffect Same answer than here :) #51 (comment)

Appreciate. Memento is really promising and I think it would even have demand if you launch it as a paid tool.
