⚠️ Before you read this article, please note that since April 19, 2023, MacPaw no longer sells, updates, or develops CleanMyMac 3. You may still use CleanMyMac 3 if you have a license; all details are in this article.

We recommend upgrading CleanMyMac 3 to CleanMyMac X at a 50% discount; learn how to upgrade.

Smart Cleanup (improved)

Smart Cleanup is not new but it was improved substantially. It has learned to find junk among your MailiTunes, and Photos files. Also, the upgraded version of CleanMyMac scans your computer more thoroughly and carefully owing to an extended version of its intelligent Safety Database. The Database includes rules and exceptions that allow CleanMyMac to scan system, applications, and user folders safely and accurately.

System Junk (improved)

System Junk is not new either, but it has gained new valuable submodules, including:

  • Document Versions, which finds multiple copies of your documents that are created automatically, as you work on docs, or manually, when you save changes. This feature is extremely helpful for active users of Sketch, Pages, Keynote, and Numbers. 
  • Xcode Junk, which can clean up your system from intermediate build information and project index generated by Xcode. This CleanMyMac ability will come useful if you, as a developer, want to save gigabytes of disk space.
  • Old Updates, which finds old versions of some application updates. Removing this type of outdated files is absolutely not risky and may free a lot of space on your Mac.

Mail Attachments

The Mail Attachment module scans your Mail application for copies of downloads and attachments, which are stored on your Mac automatically when you view your messages. Removing these files won't harm their originals which remain available in your online Inbox.

Health Alerts

CleanMyMac 3 sends you important health notifications that pop up, based on S.M.A.R.T criteria. The S.M.A.R.T system is composed of a variety of hardware sensors, which helps to identify the health and state of your Mac. When your Mac’s hardware health is at risk, an appropriate health alert appears and offers you a guidance on how to resolve possible issues.
