DaisyDisk editions & license 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:
|Stand-alone||Mac App Store|
|System version||macOS Yosemite (10.10) or newer*||macOS Yosemite (10.10) or newer*|
|Safety measures||Developer ID||Sandboxing|
|Advanced features||Deleting “stuck” files||—|
|Detect & reveal the hidden space||Only detect|
|Detect & purge the purgeable space||Only detect|
|Scan as administrator||—|
|Updates via||Built-in updater||Mac App Store|
|Registration||License keys||Apple DRM|
|Buy||Stand-alone||Mac App Store|
For macOS 10.5—10.9, legacy versions of the version are available. You can download stand-alone legacy versions here. In the Mac App Store, the corresponding legacy version is selected automatically for your current macOS version.
Migrating between editions
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 can use the both editions side by side, or delete one of them to avoid confusion (recommended). You can freely reinstall and delete either of the two editions at any time.
If you’re wondering about a migration in the opposite direction (from a purchased stand-alone license to the Mac App Store) note that it’s technically impossible without re-purchasing. Also such migration doesn’t make much sense for most people due to the limitations of the Mac App Store.
