Why macOS asks for folder access when NotchStar scans
The first time Disk scans Documents, Desktop or Downloads, macOS asks whether NotchStar may access that folder. This is macOS protecting those folders, and it is expected. It asks once for each folder.
Which scans trigger it
- Duplicates reads Downloads, Documents, Desktop, Pictures, Movies and Music.
- Compress reads Downloads, Desktop, Documents, Pictures and Movies.
- Overview reads Downloads for items untouched for 90 days.
- Space and Find walk your home folder.
The prompt appears when a scan first reaches a protected folder, not when you open the tab. Nothing is read before you press a button.
What to do
- Allow it for folders you want checked. A duplicate scan with Documents denied will not find duplicates in Documents.
- Decline for folders you would rather keep out. The scan carries on with the others.
- If you answer once and change your mind, macOS lets you change it in the Privacy settings. The exact menu path varies by macOS version, so look in System Settings for Privacy and Security.
What NotchStar does with the access
Reading is local. Disk does not send file names, sizes or contents anywhere, and removes nothing without your press. Anything it removes goes to the Trash. Read is Disk cleanup safe for the rules, and is NotchStar safe for the wider picture.
For what each section reads, see how duplicates are found and the Disk feature page.
