Sync is showing a "File system operation timed out" error

[WhiteNoise]

I can’t see much from the gif. All the plugins and themes do not help getting a clear cause of what is happening.

I believe you have this problem and you should have seen a popup warning you that Obsdian can’t save.

[MacOS]: Obsidian does not save and get stuck in a limbo state (failed to save - Timed out)

We are not sure exactly what’s going on here. We believe that on some mac systems node.fs and osx do not play well and the writing queue gets stuck. This is not an Obsidian’s problem but a deeper/lower level issue. In 0.12.5, Licat introduced a periodic safety check on the writing queue and if there is no progress, you will get a warning inviting to restart obsidian.
