Ordered steps that recover space without gambling your files. Inventory pass completed July 28, 2026, carrying 4 worked fiches.
This is the trade the domain has practiced since its shareware years: finding where space went and winning some back safely. The guides differ from forum wisdom mainly in sequence, each step lists what it protects and what it risks, because ordering is where cleanups fail.
Read them once through in order if your disk is already tight; sample individually during routine quarterly maintenance. Every guide logs its work on sheets available from the field kit, keeping audits comparable over time.
Why hourly local snapshots appear, when they thin, and the supported way to inspect or remove one.
Finder search, sorted views and du scans surface the space hogs; how to read results before deleting.
A measured sequence for reclaiming space safely: measure, empty trash families, trim caches, move libraries.
Which cache families tolerate deletion, which resent it, and the difference re-download time makes.
Reading order. Sequence beats force: trash families first, oversized strays second, caches third, snapshots only with cause.
