On MacOS the dictionary is stored outside of your vaults in ~/Library/Application Support/obsidian/Custom Dictionary.txt
. If I use my vault on different devices, I have to add exceptions on each device, right clicking red underlined words and selecting “ignore”. It adds up to lots of words.
A workaround could be to store Custom Dictionary.txt
in your vault and hardlink it to ~/Library/Application Support/obsidian/
, and your other vaults, to synchronize it across all vaults and across devices (you would need to symlink on those devices too). (A hardlink is like a symlink but it’s treat as an actual file instead).
