The Overloaded Mini

Why the Mac mini slowed to a crawl, in plain English — what was actually running, what we cleared, and what will bring it back if we leave it.

17 September 2026 · measured on the mini · cleanup partly done

The mini was doing 208 things at once. Four of them were real. Everything else had finished hours ago and was still sitting there, holding memory and watching files.

1 — Too many helpers

Every piece of work opens a helper session. When the work ends, the helper doesn't leave. It keeps its memory, and it keeps watching your files for changes.

What was running	Count
Helper sessions open	208
Doing anything at all	4
Background programs	590
Memory held by them	32 GB

2 — Too many copies

Each piece of work also makes its own copy of the project. There were 304. Every copy carries tens of thousands of small files, and the Mac watches all of them continuously.

3 — The cleaner says it's fine

A cleanup runs every morning and reports a green tick. Here is what it actually did today:

Looked at 17 of the 208 helpers — it only recognises certain names.
Removed 0 of them — it only removes things untouched for two full days, and almost nothing lasts that long.
Reported pass, because removing nothing isn't counted as a problem.

4 — One file jams the rest

The cleaner won't touch a copy that has unsaved work in it, which is sensible. But 13 copies count as "unsaved work" because of a single file that rewrites itself — package-lock.json. Nobody edited it; the computer did.

5 — What we cleared

Before

208 helpers
304 copies
40% memory free

After

7 helpers
100 copies
86% memory free

Jammed programs went from 42 down to 1. Nothing was lost: every helper that was closed can be reopened with everything it remembered.

6 — What isn't finished

The bin is still emptying. Deleting 206 copies means removing millions of tiny files. It runs in the background for hours, and while it runs the mini is busier, not calmer.
The cleaner still needs fixing. Until it stops treating that one self-rewriting file as unsaved work, this returns in a few days — as it has several times already.

The one-line version

Nothing was broken. The mini was buried under finished work that nothing was clearing away, and the thing meant to clear it has been reporting success while doing almost nothing.
