CCleaner Pro 1.18.30 — macOS

CCleaner Pro 1.18.30 still supports macOS as old as 10.10 Sierra, which is rare for a cleaner in 2024. It runs on Intel 64-bit Macs and keeps the interface in eleven languages, including English, German, and Japanese.

Clean up the usual clutter

The app targets browser caches, logs, and temporary files without asking you to sort through technical lists. It is designed to be simple and safe, so it suits a Mac that just needs a bit of breathing room.

Wipe files properly

The built-in file wiper overwrites data in multiple passes, which matters if you are clearing a drive before handing it off. You choose the file or folder, pick the overwrite cycle, and let it run.

Keep the older Macs going

Piriform still lists support back to OS X 10.10, so a 2011 iMac is not left out. Newer versions of the app are separate from the older CCleaner for Mac line, so check which one you actually have installed.

EU compliance update for June 2026

The v2.11.194 release from June 2026 was a maintenance update for EU regulatory compliance, so day-to-day use did not change much. Cleaning still works the same way — pick the categories, run the scan, and let it remove what you selected. The file wiper and browser-trace removal behave exactly as before. If you are on an older build and update to 1.18.30, the interface layout is identical. Nothing new to learn.

Run once, then after a few workdays

Run the cleaner once right after installation to clear whatever junk has built up. Then use the app for a few normal workdays before running it again. This lets you see how much space the routine cleaning recovers and whether any application you rely on keeps cache files you would rather keep. For example, your web browser might store saved form data that the cleaner flags. If you notice something missing after a cleaning pass, you can skip that category next time.

Check the list of applications the cleaner scans. It includes temporary files and recent-file lists from third-party apps, not just browsers. If you use a program that stores a long recent-file history, the cleaner will shorten it. That is usually fine, but if you depend on that history for your workflow, uncheck that item.

Review browser auto-fill before first run

The cleaner gives you control over what gets deleted. The default selections are safe, but you may want to review them before the first run. Uncheck browser auto-fill data if you rely on saved passwords or form entries — the cleaner will remove them otherwise.

For the file wiper, set the overwrite cycle to a single pass for everyday use. Multiple passes take much longer and offer little benefit on modern drives. Save the multi-pass option for when you are wiping a drive you plan to sell or give away.

If you clean your Mac weekly, the routine becomes simple: open the app, verify the categories, run the scan, and apply the cleaning. No need to change settings again unless your habits change. Keep an eye on the temporary files list — some apps generate more clutter than others, and you may want to add or remove items from the scan list as your software lineup shifts.

One practical tip: run the cleaner after a major OS update. System updaters often leave behind old installer files and cache that the cleaner can remove. A quick pass after updating macOS frees up space without any extra effort on your part.
