Despite popular belief that Macs don't require cleaning, many users struggle with storage space on their Macs. That's especially true for newer devices since Apple has ditched hard disk drives and adopted the more contemporary and faster solid-state drive technology, which often means far less storage space.

Here, system cleaner tools emerge as solutions to the problem, as these apps can effortlessly clean your device of junk files and unnecessary data. Disk Doctor for Mac is an excellent example of such an app, and today, we'll examine its functionality, features, and pricing in an in-depth review and show you how to use the tool.

Overview: Disk Doctor

Developed by Fiplab, Disk Doctor is a Mac utility for cleaning your system. It does so by deleting app cache and logs, browser data, large files, old system updates, residuals from the Trash Can, and more. Essentially, the tool automates various file erasure tasks you can do independently. It then unifies these deletion processes in a single app with a relatively modern yet sleek and easy-to-use interface.

Due to its characteristics, ease of use, and straightforward steps, Disk Doctor is always a fine addition to any Mac device. It can be helpful in various situations, including some of the following:

  • Mac is Running Out of Space – At its core, Disk Doctor specializes in cleaning your Mac's disk drive to gain more storage space. It clears your Downloads folder and Trash Can and deletes files larger than 100 MB, earning you anywhere between a few megabytes to multiple gigabytes of precious storage space.
  • Your Mac Apps are Misbehaving – Disk Doctor for Mac can also remove application caches and logs, which clears storage space and fixes issues with certain Mac apps that crash or display problems when logging in.
  • You've Finished a Large OS Update – Updating a Mac requires downloading one or many large update files, which often end up in your Mac's temporary or downloads folder and remain as residuals, even after the update completes. Disk Doctor can effortlessly locate and remove these files for you.
  • Selling or Giving Away Your Mac – As it can remove downloads, browser data, mail and partial downloads, and application caches, Disk Doctor for Mac is a fantastic tool to use if your device is going to someone else. You won't need to reinstall the OS and can sell or give away your Mac ready for use.

Apart from these basic cleaning features, Disk Doctor lacks RAM cleaning tools and extension removal features, and it doesn't remove unwanted apps from your Mac. It also only works for Apple Mail, so you can't remove mail downloads for Outlook or other third-party mail clients.

Now that we know the basics of Disk Doctor for Mac and situations in which the application can be beneficial, we can dive deeper into this system cleaning tool. Let's immediately jump into it and learn more about Disk Doctor's performance, pricing, and user ratings.

Effectiveness and Performance

Disk Doctor's scanning speed is breakneck fast. Whether you're using an HDD or an SSD, the app will scan your entire disk drive within seconds. Of course, the larger the storage device and the more files you have on it, the more it will take, but the longest time we've tested was still under a full minute.

The cleaning process is also fast. While it depends on how many files you're simultaneously deleting, it'll only take a few seconds for older Macs with HDDs. Users with newer devices and SSD storage will feel like the cleaning process is instantaneous.


If Disk Doctor's features intrigue you and you want to try the app for yourself, you'll be pleased to learn that it's among the cheaper Mac system cleaners on the market. Disk Doctor for Mac will only set you back $2.99, whereas many similar apps have price points between $20 and $60.

Therefore, Disk Doctor is undoubtedly worth it. Such a bargain shouldn't be missed, as the price is worth getting a few gigabytes of your essential storage space, especially when most modern Macs no longer allow storage device upgrades.

User Review and Comments

Regarding user satisfaction, the reviews for Disk Doctor are somewhat mixed. The app has a 3.7/5 star rating on the Mac App Store based on 280 reviews, with most of the users praising the app's simplicity and ease of use. For example, The Wickster, one of the reviewers on the App Store, had this to say:

“Great job, guys! This was the money well spent for a program! If you follow the directions, you can't go wrong!”

However, some users also say they're displeased with the app's performance. For example, a user named Wagnerda was disappointed they'd only gotten 3.3 GB of space back, saying:

“I suppose I was oversold on this product. I have been attempting to leave some wiggle room on my MBP's 250 gig hard drive, and I am very vigilant in emitting all hard drive hogs. I read a review here indicating I would get “tons” of space back. That sounded good, but I got only 3.3 GB back.”
