Do I have my vault open somewhere ? I don’t think so since my vault was only on my current workstation and sync subscription was unfortunately not an option at this time.
I created a new vault after realizing my data was lost, in order to try the recover snapshots, with no luck. This operation also allowed me to access Obsidian menus which are not available if you don’t setup first a Vault.
By using the DevTools built in an electron app, I can see all the file (their names and associated metadata at least), but it seems to be located in the cache folder inside ~/Library/Application Support/obsidian folder as stated here How Obsidian stores data and if I understand well the docs, it seems to be only data needed by the application to run, not the .md files.
Device add to iCloud: Nope
Reboot the mac: Yes but only after loosing access to my notes in Obsidian
Open the notes in a different app: Nope too.
I understand and fully agree to your point that something caused this weird behaviour, but i can’t legit find (or remember) what happened.
Nonetheless, since I can list files of approx. 12Mb in ~/Library/Application Support/obsidian/Cache/Cache_Data, I’m just wondering if those file can help me recover my .md content.
