Description
Special price for a limited time—make disk cleanup simple with Disk Diet!
Disk Diet is the original disk cleaning app for macOS, first released in 2011 and continuously refined ever since. Now with full support for macOS 15 Sequoia, it safely frees up gigabytes of wasted space by removing unnecessary files in just a few clicks.
Highlights include:
• Quick scanning that targets application logs, system logs, and caches
• Removal of outdated downloads, mail attachments, and old iOS software updates
• Cleanup of unused apps and leftover language translations
• Automatic detection of unnecessary—and often very large—Xcode developer folders
Awarded a MacWorld GEM and trusted by thousands worldwide, Disk Diet remains an essential utility for anyone needing extra space. It’s designed for speed, simplicity, and peace of mind.
Friendly support is always available, with prompt responses to any questions or concerns that may come up.

Love this app. It’s my first go-to when my drive is getting tight on space, before even emptying the trash since it does that for you. Really effective at scouring the contents of all those directories under ~/Library that I don’t want to think about myself.
Helpful in tight situations :-)
I’m not sure that this gets rid of absolutely all things that are probably unnecessary for most people, but it does categorize them and give you simple choices.
Does absolutely nothing!
It does not even delete my trash folder! I have enable the program to have all access in the Security and Privacy Settings, yet it does not do a thing. Every time I run the program it says the same thing. Free up 242 megabytes. I ‘click’ diet, program does it thing, then I run it again, and it says free up 242 megabytes again. I looked at my available hard drive space and it never changes! This is a complete waste of money!
Developer Response ,
We're sorry to hear you aren't enjoying Disk Diet. It sounds like it could be the Caches area that will get rebuilt automatically by certain apps. The idea is the app can clean out the caches that aren't needed anymore to free up space. When you get a chance, please email support so we can get this fixed up for you.
