CleanMyMac 5.7.0 — macOS

Macs collect leftovers — cache files, old app support data, downloads you forgot about — and over time they slow things down. CleanMyMac gives you a straightforward way to clear that out without digging through system folders yourself. Version 5.7 keeps the same solid foundation while adding a few practical updates.

Scans Gmail inbox for large attachments and old messages

The big addition here is email cleanup for Gmail. It scans your Gmail inbox and finds large attachments, old messages, and mailing-list clutter you can delete right from the tool. That is separate from the usual system cleaning, app removal, and large-file finder that have been part of CleanMyMac for a while. The app updater and secure file deletion are still there too. It runs on macOS 11 and later, on both Intel and Apple Silicon Macs.

Core cleaning workflow unchanged across modules

The core workflow has not changed. You open the app, pick a module — Clean, Uninstaller, or Space Lens — and let it scan. It shows you what it found and lets you choose what to remove. The interface is the same clean layout from the last few releases. If you have used CleanMyMac before, version 5.7 will feel familiar, just with the Gmail cleanup added in.

Full disk access permission trips up new users

A few things trip people up when they first start using CleanMyMac, or when they update from an older version. None of them are serious, but knowing about them saves time.

The most common issue is the full disk access prompt on macOS 27. If you skip it, the scanner will not see the system areas it needs to clean. Grant it when asked. If you clicked Deny by accident, go to System Preferences > Privacy & Security > Full Disk Access and allow CleanMyMac there.

Another snag: the Gmail cleanup tool does not connect if your browser-based two-factor authentication is set to require an app password. You need to generate an app-specific password from your Google Account settings and enter that in CleanMyMac, not your regular account password. Without it, the tool cannot scan your inbox.

People also forget to remove the old version before installing the new one. If you drag version 5.7 into Applications while the previous version is still there, you end up with two copies. The launcher might open the old one. Drag the old one to the Trash first, then install the new one.

If the Space Lens tool shows a lot of files you do not recognize, do not delete system files you are unsure about. The tool marks items it considers safe to remove, but it is still worth double-checking before you confirm. Stick with the large user files you already know about — old video projects, installer archives, duplicated downloads.

Does not run in the background unless you start it

Does CleanMyMac run in the background all the time? No. It does its scan when you open it and start a module. You decide when to run it.

Will it delete something important? The tool shows you what it found and lets you pick what to remove. The system junk module flags items that are generally safe to clean. The large-file finder shows everything by size, and you choose what to delete. So the risk is low if you pay attention to what you are selecting.

Does it work on Macs with Apple Silicon? Yes. Version 5.7 runs natively on both Intel and Apple Silicon Macs. No emulation layer is needed.

What about the email cleanup — does it read all my emails? The Gmail cleanup tool scans your inbox for large attachments and old messages. It only sees what you authorize through Google's OAuth or an app password. It does not send your mail data anywhere outside your machine. The cleanup actions are done from within the tool.

Can I use it alongside other system utilities? Yes. CleanMyMac does not interfere with other maintenance apps. It cleans files that other tools might miss, and it does not modify system configurations outside its own scan results.

Space Lens surfaces forgotten local design and media files

If you store a lot of files locally — design projects, video exports, music libraries — the Space Lens and large-file finder are worth having. They surface the stuff you forgot about and let you reclaim space without guessing where it went.

People who install and remove apps frequently will appreciate the Uninstaller module. It catches leftover folders and preference files that the standard macOS removal leaves behind. That keeps your system folder from filling up with orphaned data.

If you use Gmail heavily, especially for work, the new email cleanup is a practical addition. It cuts down the time spent manually hunting through your inbox for old attachments. It is a focused tool for a specific task, not a replacement for your mail client.

Office managers or IT people looking after multiple Macs will find it useful for occasional cleanup on shared machines. The interface is simple enough that anyone on the team can run a scan without training. And since you can install it by dragging into Applications, deploying it across a few machines is straightforward.

For casual users who just want a one-button cleanup now and then, the system junk module alone is probably enough. But the other modules are there when you need them, and they do not get in the way when you do not.
