Apologies about having to ask about this. The mouse pointer wandered and I accidentally clicked on not allowing the addition of a folder to Syncthing on a local computer. The folder and path was being automatically offered by a remote computer which was also running Syncthing where I had just added the folder of interest. The computer where the folder permissions are blocked is an Apple M2 Pro running macOS Sequoia 15.2. The version of Syncthing is Syncthing-1.27.6-1 (only because the remote Mac is older and I was trying to minimize issues by running the same version of Syncthing on both).
The folder scan shows “Stopped” in red. It indicates an error as “open operation not permitted.” If I delete the folder and recreate it, the error remains.
I also get a separate “Notice” before the folder menu on Syncthing as:
2025-01-24 13:51:13: Failed to create folder marker: open “dir path…” : operation not permitted
2025-01-24 13:51:13: Error on folder “folder name…” : operation not permitted
Any help much appreciated. If I could only edit out of a file “somewhere” protection for the folder in question…
The good news is all the other folders I created where I didn’t make an errant mouse click are syncing fine between the two computers.
Okay, thank you. Syncthing had permission to read/write to the path until the Syncthing program menu asked if I wanted to allow or not allow the path to be synced. When I accidentally clicked on not allow, that’s what changed the behavior. If permission to read/write was changed, the OS didn’t change the permission on it’s own – it was me interacting incorrectly with Syncthing and clicking the wrong response to disallow syncing in the Syncthing program menu. If clicking on the mouse menu button to disallow syncing causes Syncthing to change the permissions, then that’s fine – I can go undo what was done. Not knowing otherwise, I was assuming that choosing to disallow syncing for the path in the Syncthing menu would cause Syncthing to write to a file somewhere to not permit syncing of that path (the choice of allow/disallow was being pushed by the Syncthing program to the top of program window based on my having activated sync for the same path on the remote computer; I would have preferred to set the sync up “manually” as then the possibility of shutting down syncing to the path by clicking the wrong menu button wouldn’t have been a possibility).
It doesn’t. The button you’re presumably talking about, to ignore a folder shared by the other device, simply adds a line to the configuration to suppress the notification, nothing else. Your problem is something else and this is unfortunately the wrong line of troubleshooting.
