4. GrandPerspective

GrandPerspective is a free disk mapping tool available for Mac OS X systems. In fact, it is one of the best TreeSize alternatives for Mac. The application uses the TreeMap algorithm to display an overview of your hard drive’s contents in relation to the total capacity. 

The map is designed for easy navigation and gives an eye-catching representation of how much space each file type occupies on your Mac hard drive or external storage device.

GrandPerspective has been positively received as one of the best data visualization tools available in its class. One common theme is its user-friendly layout which provides a fast easy way to gain insight into your system’s disk usage without learning complicated algorithms or advanced coding techniques.

Its usefulness extends beyond just viewing current disk space saved as once set up you can begin tracking new files added over time with the same more accurate information visibility.

This makes it perfect for optimizing storage solutions while minimizing overall costs when practicality appropriate too.

Overall, GrandPerspective serves as one formidable benchmarking tool users swear by in forums dedicated to comprehensive drive management solutions.

This makes it easy to identify large directories or files taking up too much space on your system.

One of the great features of NCDU is its user-friendly interface. You can configure various settings such as file size format, maximum depth of scan depth, or display options from the command line interface before starting your scan.

Another useful feature of NCDU is its ability to recursively search through directories so that you can quickly locate files or folders taking up too much space on your system.

This utility can also perform du commands and a detailed analysis showing both the size of each directory and their contents down to individual files.

Who is NCDU Best For?

NCDU is primarily meant for power users who need detailed scrutiny into the structure of their file systems – system administrators or those requiring production-grade configurations would benefit from its feature set most. 

Even if you don’t fit into this category but still need total control over your system storage needs, you should consider using NCDU instead of a graphical option (except if you want something with an intuitive UI).


6. OmniDiskSweeper

Are you looking for a way to improve your Mac or PC’s performance? OmniDiskSweeper is an effective tool designed to help organize and manage the usage of hard drive space by freeing up space.

OmniDiskSweeper is a program that allows users to quickly locate and delete files they may no longer need in order to free up additional hard drive space on both Mac and PC computers.

In terms of background, OmniDiskSweeper was created by The Omni Group in 2003 with the intention of making disk cleaning easier for everyone. The software began as freeware and has been upgraded several times since its initial release.

It has an intuitive visual design that highlights file sizes as well as folder trees. This makes it easy to identify which files are taking up the most space, allowing users to make more informed decisions about what can be safely removed from their device without compromising data integrity.

The software also ensures that important system files are not accidentally targeted for removal – meaning it’s safe for anyone with little technical knowledge to use effectively. 

Who Is This Software Best For?

Overall, OmniDiskSweeper is an ideal choice if you need help clearing out old files clogging up your device’s storage, or freeing up valuable disk space fast without having any technical knowledge.

It works especially well on large hard drives where manual cleanup takes too much time — allowing users with limited time at their disposal to keep their disk usage low. They can do this without having to sacrifice any other tasks during the day or week due to long-winded cleanups.

That said, advanced users with lots of experience utilizing terminal commands may find the program too basic compared to other options out there – so consider yourself warned!


7. Disk Inventory X

Disk Inventory X is an incredibly versatile disk space analysis tool for Apple Mac users – a perfect alternative to TreeSize. It can be used to quickly scan a large hard drive or a complete folder searching for wasted disk space and helps optimize your drive’s utilization. 

Disk Inventory X does one job very well – scanning a chosen drive, directory, or folder and creating tiny graphical boxy files representing all the folders/files contained within it.

With this ‘treemap’ visual model in hand, users can get an instant vision of their system layout and available space usage which often reveals sources of unexpected surplus or blocked-off usable space they were unaware of.

Disk Inventory X is free software made by Paul Burkey and has been around since 2009 – gathering positive feedback since its release.

This utility remains actively developed with new features like integration with Finder tags being added regularly keeping Disk inventory at the top of the class when it comes to detailed scans and sector-by-sector investigation toolsets.

Who Is Disk Inventory X Best For?

If you need help identifying what is taking up storage space on your Mac as quickly as possible then Disk Inventory X is not just incredibly convenient but also surprisingly comprehensive.

This makes it great for any situation from cluttered desktop drawers to huge servers and data network infrastructures where millions upon millions of binaries are reconfigured each day such as software provisioning!


8. CleanMyMac

CleanMyMac is an app designed specifically for Mac users that helps to improve their Mac’s health and performance levels. It makes cleaning up tasks quicker with a simple interface, so it’s great for both beginners and experts alike.

Since 2009 it has been helping thousands of people supercharge their Macs through automated and manual optimization while ensuring they stay free of clutter.

The secret sauce behind CleanMyMac lies in its advanced technology which combines artificial intelligence (AI) with machine learning (ML) algorithms – the same tech used by the Google search engine & Apple Siri.

This helps ensure all system settings remain optimized at an optimal level while keeping malicious content at bay. The ML algorithms are able to detect any bugs or glitches within seconds as well as adjust system settings back to default after deep scans have been run.

Who Is CleanMyMac Best For?

CleanMyMac is suitable for anyone using a Mac OS X 10.10 Yosemite or a later version as long as there is enough free storage space available; 500 MB – 2GB depending upon the size of their hard drive/SSD drive capacity. 

This means anyone can use this program regardless of technical abilities! It truly provides an effortless way to take care of those pesky file accumulations that come with time spent online along with true peace of mind in ensuring malicious files remain off our systems at all times.

Even if you consider yourself a power user and know a lot about MacOS already – CleanMyMac still offers plenty of useful convenience for us all!
