Bug memory crush Spotlight on MacOS

[4awel]

Description

I had a problem on my mac because of the kilo of code that caused spotlight to glitch every time, As a result, each time the computer took up 350GB of system data, And no matter how hard you tried to clean the cache and so on, I even reinstalled the system, the problem still remained that my entire disk was clogged on the new laptop, As a result, I solved the problem by restarting spotlight:

We need a bit more information to triage this issue effectively. Could you please provide additional details?

The user reports that Kilo Code caused macOS Spotlight to malfunction, consuming 350GB of disk space with Spotlight index data, and provides steps they used to resolve it by resetting Spotlight.

Closing per the existing invalid label from triage.

I respectfully dispute the "invalid" label. I would like to provide more details, as this is a real, reproducible bug that causes significant disk space issues on macOS.

Why this is a Kilo Code issue:

Before installing Kilo Code, my new MacBook had no Spotlight or system data issues.

After using Kilo Code (which indexed a large codebase), Spotlight started glitching and consuming around 350 GB in .Spotlight-V100.

The problem persisted even after a full OS reinstallation — until I manually cleared the Spotlight index using the commands I provided.

As soon as I resumed normal use of Kilo Code, the same issue came back (bloated system data, Spotlight glitches).

Additional details you requested:

macOS version: Sequoia 15.7.4

Hardware: MacBook Pro M1 Pro, 2021, 512 GB SSD

Codebase size: 2–3 GB, but it breaks the Spotlight process regardless of size

Steps to reproduce (more precise):

    Install Kilo Code (latest version as of March 2025)

    Open a moderately sized codebase - in my case, a complex VueJS + NestJS project with about 150 files

    Ask Kilo Code to perform a complex refactoring task, such as: "Rename a variable across all files where it is used"

    Monitor with:
    sudo du -sh /System/Volumes/Data/.Spotlight-V100
    (size grows beyond 100 GB)

    Observe in System Settings → General → Storage → "System Data" ballooning to 300–400 GB

    Notice that Finder search and Spotlight become unresponsive

This is not a generic macOS issue - other IDEs (VS Code without Kilo, Cursor, etc.) do not trigger this behavior on the same machine with the same codebase. Only Kilo Code does.

Please reopen the issue or let me know what additional logging or diagnostic data you need. I am happy to run any commands to help you resolve this.

Thank you.

@4awel thanks for the details, I will have a look!
