Arduino IDE 2.3.4 not working on MacOS

Development Tools IDE 2.x
1

I downloaded Arduino IDE from the official website on my MacBook for the first time (Running on MacOS Sequoia), but it keeps loading by showing the app logo only.

I would be grateful if someone can help me

Thanks.

Hi @iomar360. I'm going to ask you to provide some additional information that might help us to identify the problem.

:exclamation: This procedure is not intended to solve the problem. The purpose is to gather more information.

Please do this:

  1. Close all Arduino IDE windows if the IDE is already running.
  2. Open macOS Launchpad.
  3. Type terminal in the "Search" field.
  4. Click on the "Terminal" icon.
    A "zsh" window will open.
  5. Type the following command in the zsh window:
    "/Applications/Arduino IDE.app/Contents/MacOS/Arduino IDE"
  6. Press the Enter key.
  7. Wait until you are sure the IDE startup has gone into the hang state
    (as indicated by no additional output being printed to the Terminal window).
  8. Switch back to the Terminal window if the Arduino IDE window took the focus.
  9. Press the Command+A keyboard shortcut.
    This will select all the text in the Terminal window.
  10. Press the Command+C keyboard shortcut.
    This will copy the selected text to the clipboard.
  11. Open a forum reply here by clicking the "Reply" button.
  12. Click the <CODE/> icon on the post composer toolbar.
    This will add the forum's code block markup (```) to your reply to make sure the output is correctly formatted.
    Code block icon on toolbar
    Code block icon on toolbar390×118 4.25 KB
  13. Press the Command+V keyboard shortcut.
    This will paste the output into the code block.
  14. Move the cursor outside of the code block markup before you add any additional text to your reply.
  15. Click the "Reply" button to post the output.

Please let me know if you have any questions or problems while following those instructions.
