TrimyMac finds and removes gigabytes of hidden junk — app caches, dev tool waste, old downloads, and duplicates — in minutes.
macOS 14+ · Free up to 500 MB · No subscription required to start
If your Mac keeps showing "Your disk is almost full" warnings, spinning the beach ball, or running hot under light load, the culprit is almost never the hardware. It's often the invisible layer of junk that accumulates over months and years: app caches, system logs, Xcode artifacts, iOS backups, duplicate files, and developer tool waste. A typical three-year-old Mac carries 10–40 GB of this hidden garbage. macOS gives you no built-in tool to find or remove it safely.
App caches are the single biggest drain. Every app on your Mac — Chrome, Slack, Spotify, Xcode, Final Cut — writes temporary files meant to speed things up. Most apps never clean these automatically. After a year or two of normal use, caches alone can consume 5–15 GB. The cache for a single version of Xcode's simulator runtimes can exceed 30 GB.
Developer tools make storage bloat dramatically worse. Xcode derived data — intermediate build files that are completely regenerable — routinely grows to 20–80 GB. npm's global module cache, pip's package downloads, Homebrew's cached formula downloads, and Docker image layers each add more. None of these clean themselves.
iOS device backups stored by Finder or iTunes are another major space consumer. A single full iPhone backup is 3–8 GB. Some users also keep backups from devices they no longer own.
Duplicate files can hide across folders. Photos synced from iCloud, documents copied to project archives, and downloads saved more than once can be hard to spot manually. Finding them may mean checking folders one by one.
macOS needs free disk space to function properly. Virtual memory swap files, time machine local snapshots, and Core Data scratch space all require headroom. When free storage drops below 10%, you'll notice apps taking longer to launch, the fan spinning under light load, slow file saves, browser tabs crashing, and system updates refusing to install. The fix is not buying a new Mac or subscribing to more iCloud storage — it's removing junk that should have been cleaned months ago.
TrimyMac is a free Mac disk cleaner built entirely in Swift using Apple's native frameworks. It scans 11 junk categories in a single pass: app caches, system logs, crash reports, Trash, developer tools (npm, Homebrew, pip, Cargo, and Docker), orphaned apps, downloads older than 90 days, Xcode artifacts, iOS backups, browser caches, and Mail and Messages. The scan takes under 30 seconds on most Macs and surfaces exactly what it found — by category, by size — before touching anything.
Nothing is permanently deleted without your confirmation. Cleaned files go to TrimyMac's Safe Area first, giving you a recovery window if you change your mind. The Duplicate Finder uses SHA-256 hashing for exact byte-level matching — zero false positives. The Storage Analyzer shows your entire file tree sorted by size, so you can instantly find what's consuming the most space.
TrimyMac's free tier covers all 11 cleaning categories, the duplicate finder, storage analysis, performance monitoring, and security scan with no time limit and no account required. The only restriction is a 500 MB cleanup cap in total. Most first-time users find that 500 MB is enough to feel an immediate difference. For a full deep clean (often 5–30 GB on a developer's Mac), Pro unlocks unlimited cleanup at $9.99/year or a one-time $24.99 lifetime purchase.
Compared to CleanMyMac X (a paid subscription — check MacPaw for the current price) or Disk Doctor (a paid app — check the vendor for the current price), TrimyMac offers the same core cleaning capability at a fraction of the cost. The app does not include a usage-analytics SDK, and scan results stay on your Mac.
TrimyMac covers every angle — one tool instead of five.
Automatically detects app caches, system logs, crash reports, Xcode artifacts, iOS backups, and dev tool waste across npm, pip, Homebrew, Docker, and more.
See every file on your Mac sorted by size. Find what's secretly consuming hundreds of gigabytes — large files, hidden directories, and forgotten downloads.
SHA-256 hashing finds exact duplicates — zero false positives. Recover the space taken by identical photos, documents, and archives you forgot you copied.
Live memory pressure graph — wired, active, inactive, free — plus a real-time list of top memory consumers with the option to force-quit runaway apps.
Lists LaunchAgents and LaunchDaemons for you to review; it does not judge whether they are safe.
Nothing is permanently deleted until you say so. Files go to Safe Area first — restore or delete forever from one place with complete confidence.
These screenshots are from an actual Mac — no marketing fluff.
Smart Clean — 11 junk categories scanned in parallel. Orphaned apps: 2.46 GB. Browser caches: 680 MB. Review every item before anything is deleted.
Hit "Scan All" from the Smart Clean section. TrimyMac scans 11 junk categories in parallel — fully in the background. Browse other sections while it runs.
See exactly what was found — sorted by size, name, or date. Deselect anything you want to keep. No surprises, no hidden bulk actions.
Move to Safe Area (reversible), send to macOS Trash, or delete permanently. Your choice at every step — TrimyMac never acts without asking.
Try TrimyMac with no account, no card. Upgrade only when you want unlimited cleanup.
Open TrimyMac → Settings → in the License section click Enter License Key / Restore Purchase, paste the key from your confirmation email, and click Activate. Pro unlocks instantly. Full step-by-step instructions are in the setup guide.
Your license works on a limited number of Macs at once. The seat limit is set on the license, not in the app. To move it when you are at the limit, open Settings → License → Deactivate on this Mac on the old machine to free a slot, then activate with the same key on the new Mac. See the license management guide.
Retrieve it anytime from app.lemonsqueezy.com/my-orders using your purchase email, or email [email protected] with your order number and we will resend it. More in the full guide.
Yes. Files are never permanently deleted without your explicit confirmation. By default, cleaned items go to the Safe Area — a recoverable holding folder — not the bin. You choose to permanently delete from there. System-critical files and process containers are hard-blocked from cleanup.
For complete results — yes. Without it, protected directories like ~/Library/Caches, app containers, and system logs are invisible to TrimyMac. Granting Full Disk Access in System Settings → Privacy & Security gives it the same access as Finder. Scan results stay on your Mac. The app does not include a usage-analytics SDK.
Everything — all 11 Smart Clean categories, storage analysis, duplicate finder, performance monitoring, and security scan. The only limit is 500 MB of total cleanup. Once you hit that, you're prompted to upgrade. Most people find this is plenty for a first-time clean.
Annual ($9.99/yr) renews automatically each year at the then-current price unless you cancel before the renewal date. You can cancel anytime, and you keep Pro until the end of the paid period. Lifetime ($24.99) is a single one-time payment with no recurring charges. Both include all Pro features and future updates. If you plan to use TrimyMac for more than ~2.5 years, lifetime pays for itself.
File lists and scan results stay on your Mac, and the app does not include a usage-analytics SDK. A license key and this Mac's hostname are sent to Lemon Squeezy to activate a Pro license and to re-check it about every 7 days. The app also checks trimymac.com for updates. This website loads Google Analytics.
macOS 14 Sonoma or later. TrimyMac is a native SwiftUI app built with the latest Apple frameworks — it will continue to receive updates as new macOS versions ship.
Open TrimyMac and click Smart Clean. It automatically finds and categorizes all app caches — browser caches (Chrome, Safari, Firefox), system caches, app caches (Slack, Spotify, Zoom), and developer caches — showing you the exact size of each before you delete anything. Manually, you can open ~/Library/Caches in Finder, but many caches are inside protected app containers that require Full Disk Access to reach. TrimyMac handles all of this in one pass.
Open the Storage Analyzer in TrimyMac to see your entire file system sorted by size. Typical space hogs include: Xcode derived data (20–80 GB), iOS device backups (3–8 GB each), Docker images, node_modules directories, old Downloads, and large video files. macOS's own "About This Mac → Storage" view is notoriously inaccurate — TrimyMac gives you exact file-level sizes.
A slow Mac is usually caused by low free storage, too many startup items, or runaway background processes — not hardware age. TrimyMac addresses all three: Smart Clean frees up disk space, Startup Items Manager shows everything that launches at login (disable what you don't need), and the Performance Monitor shows live memory pressure and top memory consumers so you can quit apps that are hogging RAM.
TrimyMac's free tier includes the Duplicate Finder at no cost. It uses SHA-256 hashing to find exact byte-for-byte copies across your entire drive — photos, documents, archives, videos — regardless of filename or location. Results are grouped by duplicate set so you can review before deleting. The 500 MB free-tier limit applies to cleaning, but scanning is always free.
Dragging an app to the Trash only removes the main .app bundle. It leaves behind support files in ~/Library/Application Support, preferences in ~/Library/Preferences, caches in ~/Library/Caches, and launch agents in ~/Library/LaunchAgents — often several hundred MB per app. TrimyMac's App Uninstaller finds all associated files for any app and removes everything in one step.
CleanMyMac X is a paid subscription (check MacPaw for the current price). TrimyMac's Pro is $9.99/year — with a genuine free tier, no subscription required to start. Both apps scan app caches, junk files, and duplicates. TrimyMac's key differences: the app does not include a usage-analytics SDK, no background agent running when you're not using it, and a one-time lifetime option for $24.99. If you're a developer, TrimyMac also goes deeper on Xcode artifacts, npm, pip, Homebrew, Docker, and CocoaPods caches.
