I had to revert the fix, unfortunately, as it was causing problems for other players. I'll try to figure out a solution that works for everyone & include that in the Job & Home update coming soon.
In the meantime, you could try deleting some older saves to free up space, or try playing the game via the official itch.io app, which supports macOS. You can export and import your data via the 'Extras' main menu option & it may circumvent the save memory limit.
