‘ZDNet Recommends’ What exactly does that mean?

ZDNet’s recommendations are based on many hours of testing, research, and comparison shopping. We gather data from the best available sources, including vendor and retailer listings as well as other relevant and independent reviews sites. And we pore over customer reviews to find out what matters to real people who already own and use the products and services we’re assessing.

When you click through from our site to a retailer and buy a product or service, we may earn affiliate commissions. This helps support our work, but does not affect what we cover or how, and it does not affect the price you pay. Neither ZDNet nor the author are compensated for these independent reviews. Indeed, we follow strict guidelines that ensure our editorial content is never influenced by advertisers.

ZDNet's editorial team writes on behalf of YOU, our reader. Our goal is to deliver the most accurate information and the most knowledgeable advice possible in order to help you make smarter buying decisions on tech gear and a wide array of products and services. Our editors thoroughly review and fact-check every article to ensure that our content meets the highest standards. If we have made an error or published misleading information, we will correct or clarify the article. If you see inaccuracies in our content, please report the mistake via this form

Best Mac cleaner 2021: Our favorite optimization apps

Macs are good. With these tools, you can keep them that way.

Macs are true workhorses, but as is the case with every computer, detritus builds up, filling storage space, and turning a once-speedy system sluggish. With a little bit of care and feeding, a Mac can run at its best for longer. Also, depending on what you use your Mac for, having a suite of tools and utilities that can carry out useful tasks with a click of a button is super handy.

CleanMyMac X

My absolute favorite Mac utility. One click allows you to find junk files, scan my system for threats, and look for ways to speed up my system. Then, with another click, all those tasks are carried out, quickly, efficiently, and safely. It's a great product that gets regular and timely updates, and a tool that's helped me keep many Macs running smoothly for years. Highly recommended!

DiskWarrior 5

There are a lot of tools that claim to be able to recover your data when your disk fails. 

DiskWarrior is the only one I trust with that task. With one click, you can get DiskWarrior to scan your storage drive, finds all recoverable data, and then build an error-free, optimized copy for you.

Parallels Toolbox

Not a single tool, but a suite of over 30 tools, most of which are productivity and system health tools, and all of which are super easy to use. Many do their jobs with a single click.

So, what utilities are there? There's a disk cleanup tool, image resizer, video downloader, screen recorder, archiver, clipboard history tool, GIF maker, presentation mode switch, and much more. Because there are so many parts to Parallels Toolbox, I sometimes lose track of how much I use these tools every day.

Gemini 2

One of the things that can be responsible for a lot of wasted storage space is duplicate files. It's not just duplicate files that can be a problem, but also similar files. This can be especially true when it comes to photos. Gemini 2 can scan your photos, spot ones that are similar, and lets you pick which ones to keep. 

TG Pro

The all-in-one temperature monitoring, fan control, and diagnostics for Macs. 

If you're someone who makes their Mac work hard, this is a fantastic tool for tuning the cooling system for optimal performance and keeping things running at their best.
