What is the purpose of com.apple.diskspaced? What this service does exactly?
$ launchctl list com.apple.diskspaced
{
"EnableTransactions" = true;
"LimitLoadToSessionType" = "Aqua";
"MachServices" = {
"com.apple.diskspaced" = mach-port-object;
};
"Label" = "com.apple.diskspaced";
"TimeOut" = 30;
"OnDemand" = true;
"LastExitStatus" = 9;
"PID" = 96227;
"Program" = "/System/Library/PrivateFrameworks/StorageManagement.framework/Resources/diskspaced";
};
launchctl stop com.apple.diskspaced, but the notification didn't stop, so this service could be not responsible for the HDD notifications. See also: Silencing “Your disk is almost full” notification – kenorb Dec 12 '16 at 20:40
