SpotlessmacOS says it could not verify Spotless
On the first launch, macOS may say it could not verify that Spotless is free of malware. That message appears for apps Apple has not checked yet. You can open the app from System Settings in about 20 seconds, and macOS remembers your choice.
Why the message appears
Gatekeeper, the part of macOS that checks downloaded apps, wants an app to be signed and notarized by Apple. The notarization is a scan Apple runs on software that developers submit. When an app has not gone through it, macOS shows the warning and offers only Done or Move to Trash. This build of Spotless has not been notarized yet, so you may see the warning.
Open it anyway
- Try to open Spotless once. When the warning appears, choose Done. Do not choose Move to Trash.
- Open System Settings and go to Privacy & Security.
- Scroll to the Security section. You will see a line saying Spotless was blocked.
- Choose Open Anyway, then enter your password or use Touch ID.
- Choose Open in the last dialog.
The button stays on screen for about an hour after the failed attempt. If you do not see it, try opening the app again first.
For people who use Terminal
You can clear the download flag directly. Move Spotless to Applications, then run this command:
xattr -dr com.apple.quarantine /Applications/Spotless.appThen open the app as usual. This only removes the flag macOS adds to downloads.
Check you have the real app
Download Spotless only from doolphin.co. The file is about 10 MB. If you got it from anywhere else, delete it and download it again from the official page.
If it still will not open
- Make sure you moved Spotless to Applications before opening it, and did not run it from the disk image.
- Check that your Mac runs macOS 14 or later. Older versions cannot open it.
- Restart the Mac and try again.
Write to yashraj@oth3l.com with your macOS version and a screenshot of the message if none of this works.
