Hi,
I actually currently use a server and the keychain, but I want to share
general data with offline users. I will never use the shared directory
of a user, the best way would be in / Application Support in
.localDomainMask, but I don't know why some applications can and others
cannot (the mine is signed and notarized).
Regards

That is actually wrong. It is dangerous to create world-writable files and
share them between users. If you need to share data between users that is not
fixed (e.g. it would make sense if Apple installed GarageBand loops in
/Application Support, as they will be used by all users that launch Garage
Band, but since Garage Band comes preinstalled you don't want all that disk
space for the loops to be used, you want to download them later).
If you have databases shared by multiple users, you should use a Launch Agent
plist that launches a server process, then have any instances of your app
currently running (remember, there may be multiple instances running under Fast
User Switching) talk to that process. That way, the process can also enforce
valid file formats, making sure one user can not ruin things for another user
by feeding invalid data or deleting their data.
