RawTherapee macOS Catalina FAQs

The introduction of macOS 10.15 Catalina introduced a new security and stability paradigm. In this post we will examine some answers to your most frequently asked questions about using RawTherapee on the new operating system for Apple Macintosh computers. @hiram


  1. Wonder if your bug has been reported or solved?
    a. Search the forum for the term macOS | Catalina:
    b. Search GitHub for macOS issues:

  2. App does not launch?
    a. RawTherapee must be installed in /Applications.
    Drag the app to the /Applications folder.
    b. Could be a quarantine flag on the app in the system cache.
    Clear it with xattr -d com.apple.quarantine /Applications/RawTherapee.app

  3. Can’t access external drives? File permission prompts not appearing?
    a. System Security may need to be refreshed.
    Reset the settings with sudo spctl --reset-default

  4. How do I run the CLI (Command-Line Interface)? Due to a new security protocol in Catalina, the code-signed CLI in the bundle can no longer be executed from a terminal external to the app.
    a. The CLI is provided for Catalina users as an un-codesigned binary executable located in the same folder as the codesigned and notarized .dmg. (As of version 5.8-397-g276ae214f)
    b. You must install the RawTherapee app into /Applications first. The CLI will load it’s 3rd-party libraries from there.
    b. To run, copy the CLI rawtherapee-cli from the zip folder to a directory in your $PATH.
    c. For example:
    % unzip ~/Downloads/RawTherapee_OSX_10.9_64_5.8-397-g276ae214f.zip -d ~/Downloads
    % ditto ~/Downloads/RawTherapee_OSX_10.9_64_5.8-397-g276ae214f_folder/rawtherapee-cli /opt/local/bin/rawtherapee-cli
    % export PATH=/opt/local/bin:$PATH
    % rawtherapee-cli
    RawTherapee, version 5.8-397-g276ae214f, command line.
    Terminating without anything to do.

  5. Want to test a recent dev build for macOS?
