Your Disk is almost full (super annoying notification)

On Mac OS Mojave I have this message that keeps on popping up every few minutes even when I close it. I have 10Go left and it is sufficient. I don't want to be bothered every 3 minutes by this annoying message.

MacBook Air (2018 or later)

10GB of free space is not nearly enough for your mac to perform.

The sleepimage alone may gobble that up.

The OS is always using the system drive to store caches and stuff it needs to work, to use as virtual memory and sleepimage.


Any drive needs to have some free space to perform adequately. As a rule of thumb, each drive should always have at least 10-15% free, and more so for the system drive, maybe 15-20 or 25% free.


Don't ignore or try to disable these warnings, clear some space on your drive NOW.
