Before you install
Open the downloaded disk image, drag NullDisk into Applications, then open it from Applications.
- macOS 14 Sonoma or later — earlier systems aren't supported.
- Apple Silicon or Intel — one universal build covers both.
- Folder access and macOS privacy — choose the folders to authorize. macOS privacy restrictions and Full Disk Access can still affect which files are readable.
What’s included
Radial and treemap views, local/SSH/cloud sources, and Git-aware Development Cleanup. The separate CLI offers terminal maps and machine-readable reports. Read the usage telemetry policy before installing.
Frequently asked questions
Which macOS versions are supported?
NullDisk requires macOS 14 (Sonoma) or later, on both Apple Silicon and Intel Macs.
Where do I download NullDisk?
The Download button above gives you the current notarized build straight from nulldisk.app. Check this page for any App Store availability. Always download from those official sources — never from aggregator sites.
What is NullDisk’s licensing model?
The direct-edition license permits free personal and workplace use, with no expiry. Every app feature is included. An optional one-time license removes reminders permanently; it does not unlock features. See the pricing page for license details.
How do I get help?
Email support@nulldisk.app with your macOS version and what you were doing and we will get back to you.
