DaisyDisk versions & migration

Why having two editions?

The Mac App Store guidelines limit what an app can and can't do. One of such limitations is inability to operate in privileged mode, another one is the mandatory operation in sandboxed mode.

While being generally useful (as they prevent some apps from harming your system) these requirements may influence functionality of applications that need low-level system access. In order to comply with these rules we've removed a few features from the Mac App Store edition of DaisyDisk.


Here's a complete list of differences between two editions of DaisyDisk:

Version migration

If you are our customer from the Mac App Store, you can get the stand-alone license for free.

If you migrate to the stand-alone edition, you will be able to use any of the two editions. However, migration in the other direction, from a purchased stand-alone license to the Mac App Store is technically impossible without re-purchasing DaisyDisk there.
