[Bug] Accessing external USB drive: "Failed to read this folder." #1369

Is there an existing issue for this?

  • I have searched the existing issues (including the closed ones)

Description

On macOS (Sequoia) when I try to access external USB drive I get popup with "Failed to read this folder." (BrowseLocationThread#showFailedToReadFolderDialog, invoked from:

).
Some external drives work properly, but some cannot be read - most probably when a drive contains Time Machine backup (so far confirmed with 2 such drives).

Tried the most recent nightly builds, also built locally (dmg) - the same problem. However, when I ran ./gradlew run it worked properly.

I was able to fix the problem by allowing muCommander Full Disk Access via macOS System Settings. I had to add it manually and turn the access on. Did some research, and I guess we would need to inform user to add muC to FDA and eventually open System Settings (open "x-apple.systempreferences:com.apple.preference.security?Privacy_AllFiles")?

Steps to reproduce

  1. attach USB external drive with Time Machine backup
  2. go to its folder
  3. popup appears with "Failed to read this folder.", nothing in logs

Expected behavior

Drive can be accessed.

Actual behavior

Drive cannot be accessed.
