I test Mac cleanup tools for a living — everything from the full-featured suites to the tiny single-purpose utilities. MacSweep caught my attention in 2024 because it was one of the few cleaners that showed you exactly what it was going to delete before touching anything, with no upsell flow hiding the core feature set.
Background
I started writing about Mac software in 2017 for a London-based tech publication, covering the Mac App Store utilities beat. That meant reviewing every major disk cleaner, privacy wiper, and startup manager that launched — a category that saw a lot of churn in the Catalina-to-Monterey period as System Integrity Protection rewrote what cleaners could actually touch.
Since 2021 I have written independently, focusing on macOS storage management and the privacy implications of cleaner tools. The question I keep returning to is simple: which of these apps actually earn the permissions they ask for, and which are using a cleaning UI as a wrapper for data collection?
Areas of focus
macOS storage management
System cache behaviour across macOS versions, what SIP actually protects, and where cleaners find legitimate reclaim.
Mac privacy tooling
Which cleaner permissions are necessary, which are overreach, and what a truly offline tool looks like under the hood.
Apple Silicon performance
How M1–M4 memory compression affects what cleaners report as "used RAM" and what that means for cleanup recommendations.
How I approach this work
Every cleaner I cover gets a full scan on a test Mac with a known file state — I know exactly what's there before the tool runs, so I can verify the claimed numbers against reality. I also check network traffic during scans: a cleaner that phones home during what should be an offline operation gets flagged immediately.
MacSweep passed that test cleanly. No outbound connections during scan, no telemetry on deletion, and the preview-before-delete flow means even first-time users understand what's about to happen.
