Why do I see "File System Access" dialogs?

The App Store version is sandboxed. To grant full disk access:

1. Select your USER HOME folder when prompted and click Allow FileSystem Access.
2. Open Preferences inside CRAX.
3. Click Reset File System Access.
4. Select the ROOT (/) folder of your drive (Macintosh HD) and click Allow again.

Problem after reboot?

If you lose access after a reboot (seeing "Sandbox Error"), use the following button in Preferences again to re-authorize the drive:

If the application starts but nothing happens (or the display is dark with no panels), configuration files might be corrupted.

Solution: Fully uninstall the application (including Library files) and reinstall a fresh version.

Please refer to the Uninstall Procedure section below.

Sidebar not showing:
Perform a full uninstall/reinstall to reset layout configuration.

Sidebar shows partially:
Maximize the CRAX main window (green button), then quit the application (CMD+Q). Restart CRAX. The layout should reset.

In order to see drives on the sidebar in CRAX, you must enable Devices in Finder's preferences.

1. Click on the Finder icon in the dock.
2. Go to the top menu bar, click Finder -> Preferences.
3. Select the Sidebar tab.
4. Check the boxes under "Locations" (Hard disks, External disks, CDs, DVDs, and iPods).

You can define external applications as tools within CRAX. Here is how to do it:

1. Go to Preferences > Tools.
2. Click the Add Tool Definition button (Plus icon).
3. Tool Name: Enter a name (e.g., iTerm). This will appear in the "Tools" menu.
4. Tool Path: Enter the absolute path to the executable.
   • Example for iTerm: /Applications/iTerm.app/Contents/MacOS/iTerm
   • Example for App Bundle: Use /usr/bin/open as path and add the app via parameters.
5. Shortcut: Click "Record Shortcut" and press your desired key combination.
6. Parameters: Add arguments like %p (current path) or %f (selected file).

To use Apple's FileMerge (opendiff) for comparing files:

1. Go to Preferences > Tools.
2. Add a new tool named open_diff.
3. Set Path to: /usr/bin/opendiff
4. Set Shortcut (e.g., CTRL+D).
5. Add two parameters:
   • Parameter 1: %f (File from active panel)
   • Parameter 2: %F (File from other panel)

Usage: Select a file in the left panel and another in the right panel, then press your shortcut.

To backup or transfer your configuration, you can use the external CRAX Tool Application.
