macOS 10.15.4+ Catalina FREQUENTLY ASKED QUESTIONS

  1. Wonder if your bug has been reported or solved?
    a. Search the forum for the term macOS | Catalina:
    https://discuss.pixls.us/search?q=catalina%20|%20macos%20order%3Alatest
    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.
