[launchd-dev] overrides.plist denied write access by ACLs

[Thomas Clément]

Hello all,

My product installs an agent in /Library/LaunchAgents/ and my application allows the user to enable/disable it.
To do that, I'm calling "launchctl load/unload -w" which stores the disabled state in its per-user overrides.plist file.

However I'm getting several reports from users for which it doesn't work. It turns out their overrides.plist is denied write access by ACLs.

They are also Time Machine extended attributes which may be related to the whole thing.

Have you guys seen this before?
Any idea how these ACLs got here?


Thanks,
Thomas
