Recover Space – Clean My Mac 3 Review

Clean My Mac Shotkit Review

It seems a little weird writing a review for Clean My Mac 3 on a photography site. The truth is though, Clean My Mac 3 is so generically useful to anyone who owns a Mac computer, that it would be a shame not to introduce it to fellow photographers.

Shooting digitally, we are tied to our computers whether we like it or not. Our digital files seem to be getting bigger and bigger, eating up our hard drive space.

Many of us have switched to solid state (flash) drives due to the huge increase in performance, but prices remain high, especially when pre-installed in Mac desktops and laptops.

Needless to say, our hard drive space is precious. Whilst a Macbook Pro will still be running well after 5 years, it’s probable that the storage space will have dwindled. If you can recover this space, there’s much less need to keep upgrading hardware.

Whilst this is a review of Clean My Mac 3, it’s really just a long winded recommendation. I was about to splurge $4,000 on a new laptop as my old Macbook was crawling, but decided to give Clean My Mac 3 a trial run before I made the jump.


It's a 100% Free Download

After running Clean My Mac 3 for a few minutes on the auto clean setting, I discovered I’d be able to recover around 30gb of hard drive space!

This didn’t even involve deleting large files and programs – the space was recovered solely from ‘bloat’ – i.e. useless files that were sitting dormant, taking up my valuable disk space.

I coughed up the money for Clean My Mac3, recovered 32gb of hard drive space, and found that my Macbook actually started running faster!

Apps like Mail and iPhoto which create huge amounts of temporary files in the background now opened quicker and felt much snappier.

A Review of CleanMyMac3

Even though this is a review of Clean My Mac 3, it really is just one long-winded recommendation.

Just download it for free here, run it on your Mac and see how much space you can recover.

You’ll be able to see just how much crap is lurking behind the scenes on your Mac, doing absolutely nothing except take up space.

Clean My Mac running on Macbook Pro

There’s something really satisfying when you hit the big round Clean button! If you’re a clean freak who likes to have your Mac desktop organised, there’s a great sense of satisfaction knowing that the things you can’t see on your Mac are also neatly arranged, with nothing superfluous clogging up the arteries.

I’m sure Steve Jobs would have approved of Clean My Mac 3! ;-)

There’s a lot that goes on when you click the Scan button in Clean My Mac 3, and to be completely honest, I don’t have a clue what that is! I don’t really care either – all I know is that the software is safely removing things I don’t need, helping my Mac run faster and more efficiently.

I’ve owned Clean My Mac 3 for about 2 months now and run it every week. I haven’t had a single issue with it, and have saved over 100gb of flash drive space!

Total saved so far by MacPaw

My Macbook Pro has 1 Terabyte of flash storage. Judging by the Apple hard drive upgrade pricing, an extra 500gb of flash storage costs roughly $800. That’s about $1.60 per gigabyte.

This means that Clean My Mac 3 has already saved me approximately $160 worth of space so far – not bad considering the software costs around a quarter that!


What does CleanMyMac 3 Remove?

In short, nothing you don’t want it to. You confirm the things you’d like to stay, and what you want to get ride of. The software recommends the things that you really should delete, and allows you to review anything that it deems you should look at – things like Large & Old Files.

These are the Large & Old Files on my Macbook Pro. I can choose whether I want them removed or not by Clean My Mac 3.

The things that Clean My Mac 3 will remove that won’t affect the functionality of your system include:

  • System Junk – Outdated cache files, old logs, extra application binaries, unused language files, broken app data.
  • Photo Junk – this is an eye opener for anyone who uses iPhoto. Did you know that iPhoto keeps a temporary version of every single edit you make to a photo?! This quickly adds up to a bunch of hard drive clogging files.
  • Mail Attachments – this is another one that will amaze you – your Mac stores local versions of all attachments and mail downloads that you’ll probably never need again. Clean My Mac 3 will zap them all, and make your Mail app run much smoother.
  • Trash Bins – yes, you can empty your desktop trash bin yourself, but did you know the Mail app and iPhoto also have trash bins? Clean My Mac 3 will empty them all.


What changes do you need to review?

The things that Clean My Mac 3 will analyse but require permission to touch are the Large & Old Files, and iTunes Junk.

I find the Large & Old Files scan pretty interesting as it shows me the things I haven’t used for over 6 months that are taking up a lot of space on my hard drive. I can select anything I’d like zapped, or I usually just leave it alone.

I rarely use iTunes, but it still seems to accumulate a tonne of crap. Things like outdated iPhone and iPad backups, remnants of iOS software updates and old Apps I’ve long-since deleted. I usually quickly review these and zap them all.

If you’re a heavy user of iTunes, your iTunes Junk is likely to be huge. I have zero music in my iTunes, but still Clean my Mac found all this crap to remove.

What else does Clean My Mac 3 do?

Clean My Mac 3 also includes some useful utilities that you can choose to run occasionally. These include:

  • Uninstaller – Here you can choose to safely uninstall any app from your Mac. It sorts them by file size, so you can easily see what’s taking up valuable hard drive space. When you do uninstall an app, it’s often interesting to see the associated files that are removed with it – things that would have remained had you simply dragged the app to the trash, like you may have done in the past.
  • Maintenance – this includes a number of system optimisations, including running maintenance scripts, flushing DNS caches, rebuilding of stuff, speeding up stuff… Basically keeping your Mac running like a boss.
  • Privacy – instantly remove your porn browsing history, along with traces of your online and offline activity.
  • Extensions – this is a cool one. It removes all those plugins and extensions you installed long ago but have forgotten about.
  • Shredder – I’ve never used this, but it erases any sensitive data completely. Maybe a good one for any financial docs you want to get rid of.

Utilities of Clean My Mac 3

Another really cool feature of Clean My Mac 3 that I use almost every day is the ability to free up RAM at the click of a button.

When using Lightroom 6 or Photoshop and it starts to crawl, one way I try and free up some RAM is to close other applications, such as my browser if Ihave a lot of tabs open.

If this isn’t convenient, I just click on the Free Up RAM button in Clean My Mac‘s task bar, which seems to do a great job of reallocating RAM to the app I’m currently using.

One final thing I like about Clean My Mac 3 is being able to view all of my system’s most important statistics, all in one well designed dashboard.

Sure, this info is available elsewhere on a Mac, but it’s nice to have it only a mouse click away, all in one spot.

You can also run the RAM freeing utility from here too.

Final Words

Sorry this wasn’t much of a balance review of Clean My Mac 3, but the truth is, I don’t really have anything bad to say about this excellent piece of software!

It sets out to remove unnecessary files from your Mac and make it run better, and achieves that with a beautifully designed interface that’s incredibly satisfying to use.

We all buy expensive hardware, then moan about having to pay for software. With so much pirated or free software available, it’s easy to forget that there’s real people out there working very hard to build useful software that’ll make our digital lives easier, and ultimately save us money. There are 70+ people working at MacPaw doing just this!

I’ll just finish this review of Clean My Mac 3 off by saying that this piece of software was the only piece of software I bought in 2015 for my Mac, and I’m extremely happy with it. I’d also go as far as to say that it should be on every Mac owner’s computer.

  • Thanks for this review. I was able to clear up approx. 60gb in just over an hour. I also got the Gemini app., great add on! It allowed me to clear out duplicate files very easily.

  • Wholeheartedly agree. I downloaded this software on my old 2009 MacBook pro which was clogged with all sorts of old stuff / files / 145gb of iPhoto. The HD was maxed out and this software found nearly 20gb of junk. And that was just the recommended stuff. I haven’t even gone through the stuff it flagged for me to check.
    The MBP runs much better. I now run this on both my Imac and my MBP. Well worth the price if you ask me.

  • Had already bought it before I read your review. I agree with every word. Simple to use and very, very effective. Worth every penny.

  • Its a bit cheeky to state that Steve Jobs would love it.

    From what I’ve heard – the official Apple line has been “get that off your computer, it does more harm than good”.

    Still, going to give it a try tonight….
