How to access a launch daemon's values/ system defaults value

Question

So I am trying to silence the "Your Disk is Almost Full" notification from a mac running Mojave, as right now it pops up way too frequently and it is so annoying.

I followed all answers from this thread but none of them work with Mojave.

However, I made some progress as @kenorb's answer includes this command:

grep -A6 debugLog <(strings $(find /System/Library/PrivateFrameworks -name diskspaced -print -quit))

which does give some insight into how things have changed, as when I run a modified version of it, I get this:

MacBook-Pro-7:~ QH$ grep -A15 debugLog <(strings $(find /System/Library/PrivateFrameworks -name diskspaced -print -quit))

debugLog (BOOL) - log additional debug information. Default: NO
Commands:
removeAllNotifications - Removes all scheduled and delivered user notificiations.

Now I don't understand much about that command or macOS daemons at all, but it seems to me that the lowSpaceTimer or setLowSpaceTimer: might be the key to fixing things. If I can get access to one of them, and set the timer to be something high enough, I will finally get some closure on that annoying pop up. The thing is... I have no idea how to access it.

I've tried:

defaults read lowSpaceTimer

defaults read com.apple.diskspaced lowSpaceTimer

defaults read com.apple.diskspaced (this outputs the minFreeSpace k-v entry I wrote while trying to get it to work, but does nothing to help things as minFreeSpace is obsolete)

Right now the popup shows up once every 6 minutes and it's driving me insane when I try to get work done.

Answer 1

It's most likely not the answer that you're looking for, but suddenly I discovered a simple and trivial thing - "do not disturb" mode silences that notification, along with all the others of course...

I know that it's not a proper solution, but I'll stick with it by now. How could I've been so blind :D

Answer 2

Try the following command:

defaults write com.apple.diskspaced removeAllNotifications -bool true

Answer 3

defaults read com.apple.diskspaced yields:

{
     checkAllVolumes = 0;
     debugLog = 1;
     freeSpaceWarningLevel = 4;
     minFreeSpace = 4;
     removeAllNotifications = 0;
     warningInterval = 3600;
}

Now you can change it with, say, defaults write com.apple.diskspaced freeSpaceWarningLevel 1, and restart: killall diskspaced.
