For users seeking to optimize their Mac without resorting to illicit means, several alternatives exist:

If you have a .edu email address, contact MacPaw support. They occasionally offer 50-70% discounts for students. Alternatively, check your university's software portal—many universities license CleanMyMac X for campus use.

These usually last 24–48 hours before MacPaw files a DMCA takedown. By then, thousands of users may have downloaded malware.

When you search for terms like "CleanMyMac X crack" or "activation code" on GitHub, you are entering a grey area of the internet. While GitHub is a reputable platform for developers, it is also used by bad actors to distribute malware.

Here is why those "top" results can be dangerous:

Step 4: Reset your passwords

Step 5: Run a malware scan

If any of these steps show red flags, back up your documents (not applications) and do a clean reinstall of macOS.
