How to silence “Your disk is almost full” notification on MacOS Mojave 10.14.1 (18B75) I'm getting this message every 2 min and it really drives me crazy!!! I already tried following things that were suggested here. It still pops-up every 2 min.

Some outputs of my machine:

$ defaults read com.apple.diskspaced
{
    checkAllVolumes = 0;
    debugLog = 1;
    freeSpaceWarningLevel = 1;
    lastWarningDate = "2020-05-05";
    minFreeSpace = 1;
    removeAllNotifications = 1;
    warningInterval = 36000000000;
}


I set these values by myself and also tried other values but nothing worked.

$ grep com.apple.diskspaced /var/log/system.log


I set the debug level to 1 (as you can see from the defaults before) so I thought maybe there is something in the logs. Turned out that there is nothing.

I also tried something that is mentioned here.

$ grep -A6 debugLog &lt;(strings $(find /System/Library/PrivateFrameworks -name diskspaced -print -quit))
debugLog (BOOL) - log additional debug information. Default: NO
Commands:

Maybe this helps somebody to understand this service and helps to solve this bug.

PS: Yes I know that it isn't the best solution to ignore this issue BUT I can't afford a new mac and I can't delete any files because I already did! I only have 128 GB and 80 of them are programs the rest is reserved for MacOS. All files are on a separate SD-Card.
Put the programs on an external USB drive. They need no special write speed and you’ll be super happy once you get enough space for the OS to breathe. 

You’re right 128 GB is too small to let everything sit where it gets installed. I’d say you should have 15 GB free on the root filesystem for the best experience.
