Apply Macro to Files Doesn't Wait for "Importation"

I’m trying to apply a macro to files, but I get the following error when the macro runs:

File Error
This operation cannot be done until importation of (filename) completes.

I can reproduce the problem reliably by creating a simple macro like this:


and applying it to a single file using the “Apply Macro to [Files…]” button in the Manage Macros window. The file I’m trying it on is 500 megabytes, and takes 1-2 seconds to load, during which time Audacity temporarily displays diagonal lines in the waveform view. The macro seems not to be waiting for the file to load before proceeding with the Amplify effect.

Did I miss something? Is there workaround, or a macro command like “Wait Until Loading Completes”?

I’m using Audacity 2.3.2 on macOS 10.14.5.
Try setting “When importing audio files” to “Copy uncompressed files into the project (safer)”.
Does that fix it?

Thank you! Changing that setting to “safer” did the trick.
