Your Mac is slowing down. You see the "disk almost full" notification every morning, and honestly, it’s annoying. You've probably heard of CleanMyMac X, the shiny utility from MacPaw that promises to fix everything with one big button.
But is it actually any good? Or is it just "digital snake oil" like some forum purists claim?
I’ve spent a lot of time poking around the internals of macOS. I’ve seen the software change from a simple junk-remover to the 2026 powerhouse it is today. There’s a lot of noise out there. Let’s get into what’s actually happening under the hood of your computer when you click that "Scan" button.

The "Garbage" Debate: Why Experts Are Split
If you head over to the Apple Support Communities, you’ll find people who hate CleanMyMac X with a burning passion. They'll tell you that macOS manages itself. They'll say "don't install third-party cleaners, ever."
They aren't technically wrong. Apple has built-in maintenance scripts that run in the middle of the night. macOS is pretty good at managing its own memory.
But here’s the reality: most people don't want to dig through ~/Library/Caches to find 15GB of old Spotify cache files. Most people don't know how to flush their DNS cache using Terminal commands. CleanMyMac X basically puts a friendly face on these complex tasks. It's a convenience tool. You’re paying for the time you save not being a system administrator.
What Does CleanMyMac X Actually Do?
It’s not just a "delete" button. The software is split into several modules, and some are way more useful than others.
The Smart Scan
This is the heart of the app. It looks for "system junk," which sounds scary but usually just means old log files, localization files (do you really need your Mac to speak 40 languages?), and broken download bits. In my recent tests, it found about 8GB of "smart-selected" junk that was 100% safe to toss.
The Uninstaller
This is the hidden gem. When you drag an app to the Trash, it leaves behind "zombie files"—little configuration folders and support documents that stay on your drive forever. CleanMyMac X tracks these down. It’s the difference between a clean house and just shoving everything into the closet.
Moonlock Engine and Security
MacPaw integrated something called the Moonlock Engine. It’s a malware scanner specifically tuned for macOS. While it won't replace a hardcore enterprise security suite like Bitdefender for high-risk users, for a regular person browsing the web, it’s a solid layer of defense. It flags adware and "PUAs" (Potentially Unwanted Applications) that Apple’s built-in Gatekeeper sometimes lets slide.

Is It Safe?
Yes. It’s notarized by Apple.
That’s a big deal. It means Apple’s servers have scanned the code and confirmed it doesn't contain malicious components. If it was "malware," it wouldn't be sitting on the Mac App Store right now.
However, you should still be careful. I always tell people to review the "System Junk" list before hitting delete. While the Safety Database is huge (based on 15 years of data), software can still make mistakes. Don't just blindly click. Look at what’s going into the bin.
The Performance Myth
"Will it make my Mac 10x faster?"
Probably not.
If you have a brand-new M3 or M4 MacBook Pro with 32GB of RAM, you won't notice a difference. Your Mac is already a beast. But if you’re rocking an older Intel Mac or a base-model Air with an SSD that’s 95% full, then yeah, it’ll feel snappier. SSDs slow down significantly when they run out of "breathing room." By clearing out 20GB of cache and old iPhone backups, you’re literally giving your hardware room to think.
Pricing: The 2026 Reality
The pricing model has changed a bit recently. You’ve basically got two paths:
- The Subscription: Usually around $35–$40 per year. This gets you every major update.
- One-Time Purchase: It’s around $120. The catch? You only get updates for the current major version. If they release a "CleanMyMac Ultra" next year, you might have to pay to upgrade.
Personally, I think the subscription makes more sense if you’re a Setapp user (the "Netflix for Mac apps" service), as it's included there for no extra cost.

Moving Forward With Your Mac
If your machine feels sluggish, don't just buy software immediately. Start with the basics.
Check your Activity Monitor. See if a rogue Chrome tab is eating 4GB of RAM. Use the built-in Storage Management tool (Apple Menu > System Settings > General > Storage) to see what’s actually taking up space. It’s free and built right in.
If those tools feel too basic or you're tired of hunting for hidden files, then CleanMyMac X is a great next step. It’s built for people who want their computer to "just work" without learning how to use the Command Line. Just remember: it’s a tool, not a miracle worker. Use it once a month for a "deep clean," and your Mac will likely stay in much better shape over the long haul.
Download it from the official MacPaw site or the App Store—avoid "cracked" versions from third-party sites, as those often carry the very malware you’re trying to avoid.
