How to Fix Installation Issues on Mac?

Fix FilterPixel launch problems on macOS with proper .dmg installation steps, Gatekeeper permissions, and a troubleshooting FAQ.

If you're facing problems launching FilterPixel on your Mac, it's usually because the app wasn't installed correctly. Follow these steps to ensure a smooth installation.

Step 1: Download the Installer

  1. Go to the FilterPixel Download Page
  2. Download the FilterPixel .dmg file to your Mac.

Step 2: Open the Installer

  1. Locate the downloaded .dmg file (usually in your Downloads folder).
  2. Double-click the file to open it.

Step 3: Install FilterPixel

  1. A new window will appear showing the FilterPixel app icon and the Applications folder.
  2. Drag the FilterPixel app icon into the Applications folder.

Important: Running the app directly from the .dmg file can cause errors.

Step 4: Launch FilterPixel

  1. Open the Applications folder on your Mac.
  2. Double-click FilterPixel to launch it.
  3. (Optional) Right-click the FilterPixel icon in the Dock and select Keep in Dock for quick access.

Step 5: Allow Security Permissions (if prompted)

The first time you open FilterPixel, Mac's Gatekeeper might warn you since the app is downloaded from the internet.

If you see the message "FilterPixel can't be opened because it is from an unidentified developer":

  1. Go to System Preferences → Security & Privacy → General.
  2. Click Open Anyway next to FilterPixel.
  3. The app will now launch normally.

Step 6: Verify Installation

  • Make sure you're opening FilterPixel from the Applications folder (not the mounted .dmg).
  • Once running, you're ready to start culling!

Tip: After installation, you can safely eject the .dmg file and delete it — the app is already copied into Applications.

Troubleshooting FAQ

1. The app keeps bouncing in the Dock but won't open.

  • Quit the app, restart your Mac, and try again.
  • Check Security & Privacy → General for any blocked permissions.
  • Reinstall by deleting FilterPixel from Applications and dragging it again from the .dmg.

2. I can't drag the app into the Applications folder.

  • Ensure you have admin rights on your Mac.
  • Try dragging while holding the Option key.
  • If Applications is locked, unlock it via Finder → Applications → File → Get Info → Unlock.

3. I see "Permission denied" or "Unidentified developer" errors.

  • Open System Preferences → Security & Privacy → General and click Open Anyway.
  • Alternatively, right-click FilterPixel → Open (this bypasses the security warning once).

4. The installer window doesn't show the Applications folder.

  • If the Applications folder alias is missing, open Finder → Applications manually and drag the FilterPixel icon into it.

5. I installed but the app still shows errors.

  • Delete FilterPixel from Applications.
  • Re-download the latest version from the Download Page.
  • Reinstall following the steps above.
