Get started with the Perfecto desktop app

To help you transition, Perfecto offers a desktop app that makes the legacy UI available beyond the EOL of Flash. This article explains how to get access to the app, install it, and start using it. If you encounter any issues along the way, check the Troubleshooting section.

The Perfecto desktop app is identical to the legacy Perfecto UI. For more information on using it, see our legacy documentation.


This section provides solutions for errors you may encounter when installing or launching the Perfecto desktop app.

Error Description Solution
"Perfecto.App.dmg" can't be opened because Apple cannot check it for malicious software. This software needs to be updated. Contact the developer for more information. In macOS Catalina and macOS Mojave, the app may fail because it has not been notarized or is from an unidentified developer.

Perform the following steps:

  1. Open a command-line window and navigate to the download directory.

  2. Run the following command:

    xattr -d Perfecto.App.dmg

Alternatively, you can temporarily override your Mac security settings, as follows:

  1. Go to System Preferences > Security & Privacy > General tab.

  2. Click Open Anyway to confirm your intent to open or install the app.
