Where CleanMyMac is better
- It does much more. Malware scanning, performance monitors, an app uninstaller and updater, and duplicate finding are part of one app.
- It is established. It is notarized by Apple and sold on the Mac App Store, and its listing cites more than 16 years of experience.
Where StorageJanitor is better
- One price, once. $9.99 with no subscription to cancel.
- It explains before it removes. You see what each item is and why it is or isn't safe.
- It is conservative. Only caches, logs and what is already in the Trash are deleted. Everything else goes to the Trash, and items marked Keep can't be selected (except an app's own data when you uninstall that app).
- It does one job. No malware scanner and no menu-bar monitor. Nothing runs in the background unless you turn on the low-disk warning.
Which one to choose
Choose CleanMyMac if you want one app for cleanup, malware checks and maintenance, and you're fine with its price.
Choose StorageJanitor if your problem is a full disk, you want to understand what is using it, and you'd rather pay once.
