Get more disk space for your Mac

Stacks Image 3908

At some point your Mac will show an alert that it's running low on disk space. When this happens, it will slow down tremendously and will no longer have room to install new apps or for basic system functions.

In the past, it's been tricky to find out how to get back some of this space. New versions of macOS have made it a bit easier, although it's a lot of clicks and hunting, plus it won't show things like system logs or mail downloads.

Now with Disk Diet, the original disk cleaning app first released in 2011, it only takes about a minute to free up gigabytes of unnecessary files. Let it sort through the 10 different areas to clean out and save your time for better things.

Download the free trial today and see how easy it is to get disk space back.

Disk Diet requires macOS 10.10 or newer. Compatible with Mojave and Catalina.
One license is valid for up to 3 Macs for personal or business use.
No subscription required.
All updates to 5.x are free.

It's Fast

Disk Diet is extremely fast because it uses Grand Central Dispatch (GCD), a technology in macOS that allows the use of every single CPU core.

During a clean, the only limiting factor is the speed of the drive.

With a modern SSD, it only takes about 10-20 seconds to scan and determine which files can be removed to free up space.

Get Back Gigabytes

It's likely right now that there are gigabytes of space on your Mac that are being taken up by files that are either forgotten or hard to find.

See the handy space bar at the top of Disk Diet that displays stats about the drive along with how much of the used space is junk and can be safely freed up.

Removed Unused Applications

Once common source of wasted space is applications that haven't been used in a long time. Disk Diet gives the option to automatically select applications that haven't been used:

  • In the last month
  • In the last year
  • In the last 2 years
Or individual applications can be chosen from the list.

Eight Languages

Disk Diet has been localized for eight languages to ensure that it's clear what each area is for before cleaning anything. Just click the help icon on the right of an area to get a helpful popover.

Disk Diet is available in:

  • English
  • French
  • German
  • Italian
  • Spanish
  • Russian
  • Japanese
  • Chinese (Simplified)

An example of the Caches help popover in both English and Japanese.

Mojave & Catalina

Disk Diet fully supports both macOS 10.15 (Catalina) and 10.14 (Mojave). In-app guidance provides support on how to enable all areas for cleaning in both versions.

Dark and light mode are both supported, so it looks great with either one.

In addition, on Catalina it is notarized by Apple, and uses the Hardened Runtime to ensure it's the original from Tunabelly Software and hasn't been tampered with.

How to use Disk Diet

Disk Diet is easy to use, with in-app prompts on how to set everything up so there isn't an in-depth tutorial.

Here are some helpful tips to help out:

  • The App Store version is sandboxed and will prompt once to choose some folders so it has access. For extra help, read this.
  • Cleaning system logs and extra languages requires a helper app which can be downloaded here: Disk Diet Helper.

Disk Diet digs into Mac files you may not need and frees up a lot of storage; I’m talking about gigabytes of storage the first time you use it. Noodle Mac : Disk Diet Review
